Aim: selection of a traction motor for electric freight transport operating in the Arctic.
Methods: To achieve this aim, the main characteristics of existing types of DC and AC electric motors were considered, as well as data on the use of one or another type of motor in modern electric vehicle.
Results: A comparative analysis of the most common motors has led to 2 main leaders - a permanent magnet synchronous motor (PMSM) and an induction motor (IM). Both types of motors are fully suitable for solving the aim. However, as it turned out later, PMSM is more often used for light vehicles, while IM in most cases is used for heavier vehicles.
Conclusion: As a result of the analysis, it was decided that for electric transport operating in the Arctic, the best option is to use an induction motor as a traction motor.

The commissioning of nuclear power plants in Belarus sets out wide tasking for the efficient usage of electrical energy in various electrical systems, instruments and devices. Specifically, it concerns the stationary and special-purpose electric motors. At present, they use bipolar motors with a collector – the switch of the motor armature windings during its rotation. However, there is a completely different type of motors that does not require a collector – the unipolar electric motor-generator. Some of its properties allow it to be used where the commutator motor is unsuitable, for example, in explosive and fire hazardous environments (sparking on the collector is unacceptable), in precision devices where extreme smoothness and vibration lack are required, etc. Physico-mathematical foundations of the unipolar motor-generator (moving media electrodynamics, Lorentz force, unipolar induction, magnetohydrodynamics) are described in a number of monographs and textbooks, for example, in [1–4]. The purpose of this article is to pay attention to the technical feasibility of the unipolar motor-generator in a design with separated conductors in the rotor drum.

The increase use of vehicles with combustion engine has caused intensive exploration of fossil fuels and severe pollutions. The replacement of this engine with electric motor is expected to solve both problems. For optimal selection of the motor, assessment of its performance is necessary. This may be carried out by comparing the performance of the motors used for powering electric motorcycle. This paper presents the performance comparison of 2 motors powering a modified motorcycle. The engine of the motorcycle was successively replaced with BLDC motor and DC motor and their performances were measured. The motorcycle was loaded with 1 and 2 passengers with the total weight of 59 and 109 Kg, respectively. The motorcycle speed (km/h) was adjusted up to 30 km/h. The results of the test indicate that DC motor requires power of 557.74 Watt at the speed of 317.04 rpm and generates torque of 16.81 Nm with energy consumption of 41.55 km/kWh. For the BLDC motor, it requires power of 526.62 Watt at the speed of 316.78 rpm and generates torque of 15.88 Nm with energy consumption of 50.59 km/kWh. For the same distance, DC Motor enables generates higher torque than BLDC motor. However, BLDC motor may present lower energy consumption per kWh than DC motor.

Abstract An electric hoist could be considered as the most important component of an electric overhead crane. Electric hoists are material handling equipment used for lifting, lowering, and transporting materials and products. They are powered by an electric motor and have a controller to adjust the lifting parameters. Three-phase induction motors are most often used as electric lifting motors for bridge cranes. This paper concerns the design of the power of the electric lifting motor for an electric hoist of the single girder bridge crane with the 500 kg load capacity. It represents the design of the electric lifting motor according to a commonly used scheme for the design of electric motors, from the power at a uniform load to the relative load of the motor. Based on the input data, the necessary motor parameters are calculated using Microsoft Excel. The main parameter is the static power of the motor, the calculated value of which is 0.823 kW. Based on the value of this power, a three-phase induction motor 1.1 kW, MS90-4 is selected. This electric lifting motor is suitable for the above-mentioned bridge crane, as it meets the condition of torque overload.

Abstract: The continuous use of an electric motor in some industries causes the electric motor to malfunction early. Such damage is generally caused by overheating. Therefore, to overcome the problem of overheating, most industries use two motors that work alternately. Both electric motors function as running and standby which are generally controlled manually by the operator or using a time delay relay (TDR). However, the control of both motors by the operator is not effective because it allows human error to occur. The use of TDR is also ineffective because it does not make the temperature of the electric motor a reference in controlling the work of the two electric motors. This research aims to produce a prototype that can monitor the temperature of the electric motor in real-time and control the electric motor based on the temperature of the electric motor. The Wemos D1R2 is used as a processor to control both electric motors and transmit the temperature of the electric motor to a smartphone via the internet. The MLX90614 sensor is used as an infrared-based temperature sensor. Based on the results of testing the overall performance of the prototype, it is known that the temperature readings of the electric motor are quite accurate with mean error and standard deviation of 0.13oC and 0.15oC, respectively. The prototype is also capable of controlling both electric motors automatically and controlling a cooler via a smartphone. Keywords: Electric Motor; MLX90614; Overheating; Wemos D1R2. Abstrak: Penggunaan sebuah motor listrik secara terus menerus pada sebagian industri menyebabkan motor listrik tersebut mengalami kerusakan lebih awal. Kerusakan tersebut umumnya disebabkan oleh panas berlebih. Oleh karena itu, untuk mengatasi masalah panas berlebih tersebut maka sebagian besar industri menggunakan dua buah motor yang bekerja secara bergantian. Kedua motor listrik tersebut difungsikan sebagai running dan standby yang mana umumnya dikendalikan secara manual oleh operator atau menggunakan time delay relay (TDR). Namun, pengendalian kedua motor oleh operator tidaklah efektif karena memungkinkan terjadinya human error. Penggunaan TDR juga tidak efektif karena tidak menjadikan suhu motor listrik sebagai acuan dalam mengendalikan kerja kedua motor listrik tersebut. Penelitian ini bertujuan menghasilkan sebuah prototipe yang mampu mengawasi suhu motor listrik secara real-time dan mengendalikan motor listrik berdasarkan suhu motor listrik. Wemos D1R2 digunakan sebagai prosesor untuk mengendalikan kedua motor listrik dan mengirimkan suhu motor listrik ke smartphone melalui internet. Sensor MLX90614 digunakan sebagai sensor suhu berbasis infra merah. Berdasarkan hasil pengujian kinerja prototipe secara keseluruhan diketahui bahwa hasil pembacaan suhu motor listrik cukup akurat dengan mean error dan standar deviasi masing-masing 0,13oC dan 0,15oC.

Full textAbstract:
Regenerative braking is very important for increasing the total range of an electric vehicle. In this study, an embedded controller, including regenerative braking, is designed and implemented for an electric vehicle. Experimental studies are carried out on an electric vehicle driven by two in-wheel electric motors. In-wheel electric motors are preferred in light electric vehicles, since they are both highly efficient and supports regenerative braking. In our embedded controller application, the in-wheel electric motor is operated in both the motor mode and the regenerative braking mode. The in-wheel electric motor control embedded software is developed in the Matlab/Simulink environment. The developed software is embedded in the DSP STM32F407 microcontroller, which has ARM Cortex-M4 core. The in-wheel electric motor is controlled by a fuzzy logic controller in the motor mode, the in-wheel electric motor - in the regenerative braking mode. Different PWM (Pulse Width Modulation) ratios are applied to the wheel electric motor in the regenerative braking mode. The experimental data are recorded in real-time by transferring to a PC on the electric vehicle. The performance of the study is proven with experimental tests.

Purpose Analysis of test data monitored for a number of electric machines from the low volume production line can lead to useful conclusions. The purpose of this paper is to trace the machine performance to find quality-related issues and/or identify assembly process ones. In this paper, the monitoring of experimental data is related to the axial flux motor (AFM) used in hybrid electric vehicle (HEV) and in electric vehicle (EV) traction motors in the global automobile market. Design/methodology/approach Extensive data analyses raised questions like what could be the causes of possible performance deterioration of the AFM and how many electric motors may not pass requirements during operation tests. In small and medium research units of AFM for HEV or EV, engineers came across a number of serious issues that must be resolved. A number of issues can be eliminated by implementing methods for reducing the number of failing AFMs. For example, improving the motor assembly precision leads to reduction of the machine parameters deterioration. Findings Assembly tolerances on electric motor characteristics should be investigated during motor design. The presented measurements can be usable and can point out the weakest parts of the motor that can be a reason for the reduced efficiency and/or lifetime of the AFM. Additionally, the paper is addressed to electric motor engineers designing and/or investigating electric AFMs. Originality/value Performance of AFM was monitored for a number of identical motors from low volume production line. All tested motors were operated continuously for a long period of time and the tests were repeated every few weeks for half a year to check the reliability of motor design and indicate how much the motor parameters may change. The final results point how many motors fail the requirements of motor performance. A few batches of AFM were selected for testing. Each batch represents a different size (nominal power) of the same type of AFM.

Since permanent magnet direct current (DC) motors are mainly used in various industrial automation applications, the demand for electric motors is increasing rapidly. However, in the mass production of electric motors, often, only random inspections are used to check the specifications and performance of electric motors. For manufacturing or engineering application staff to have a more thorough understanding of the characteristics of the motor, it is necessary to conduct a full or quick inspection during the production process to ensure the quality of the electric motor. Based on this, this literature review reveals several methods and algorithms often used to estimate DC motor parameters, given the importance of knowing the parameters of the DC motor and the lack of research on estimating the parameters of the DC motor.

Full textAbstract:
In the last decade, a number of research works in electrified vehicles have been devoted to the analysis of the electric consumption of battery electric vehicles and the evaluation of the main influencing factors. The literature analysis reveals that the electric motor size, efficiency, and driving condition substantially affect the electric energy stored in the vehicle battery. This paper studies the degree of sensitivity of energy consumption to electric motor size and to its efficiency map characteristics. In order to accomplish this task, three electric motors whose parameters are re-scaled to fit the maximum power torque and speed with different efficiency maps are simulated by installing them on two commercially available battery electric vehicles. This allows for isolating the influence of the efficiency map on electricity consumption. The original characteristics of the motors are then used to evaluate the influence on the electricity consumption of both the size and the efficiency characteristics. The results of the simulation revealed that the influences of the efficiency map and the electric motor size can be around 8–10% and 2–11%, respectively. When both factors are taken into account, the overall difference in electricity consumption can be around 10–21%.

This paper presents an analysis of electric motor drives for the propulsion system of a battery electric vehicle (BEV). It offers a comprehensive review and mathematical analysis of both AC and DC motor drives commonly used in electric vehicle (EV) applications. Various types of electric motor drives have been utilized for EV propulsion, and among them, the Permanent Magnet Synchronous Motor (PMSM) drive stands out as the optimal choice. The PMSM drive demonstrates superior performance and numerous advantages, including a robust structure, high efficiency, compact size, reduced maintenance costs, and minimal torque ripple. These characteristics make it a more suitable option for EV propulsion compared to other motors. This study investigates the performance of the PMSM drive in comparison to other competitive electric motor drives used in EV propulsion systems, namely the Brushless DC Motor (BLDCM), the Induction Motor (IM), and the Switched Reluctance Motor (SRM). The evaluation focuses on key criteria for electric motors—output power and torque densities, essential for effective application in EV propulsion systems. The paper introduces novel mathematical and analytical relationships between two prominent PM motor families: the PMSM and the BLDCM. Both motors are highly competitive in terms of power and torque output. The mathematical analysis and graphical plot simulation results demonstrate that the PMSM drive offers the highest power and torque densities among the three motor drives. Specifically, the PMSM drive exhibits 29.90% greater power and torque densities than the BLDCM drive, 88.68% greater than the SRM drive, and an impressive 200% greater than the IM drive, all under the same operating parameters such as power factor, size, rating, and efficiency. These findings highlight the significant advantages of the PMSM drive, positioning it as a superior choice for electric vehicle propulsion systems.

One of the most common types of AC electric machines are asynchronous electric motors. Because of their simple and reliable design, they are used in many industries. In this paper, the object of research is an asynchronous electric motor with a short-circuited rotor. To ensure the normal operation of an asynchronous electric motor, the heating temperature of its active parts should not exceed the maximum permissible values, which are determined by the corresponding class of heat resistance of the insulation system used in the electric motor. In asynchronous electric motors, the stator winding is the most thermally vulnerable node, which is the first to fail when the temperature of the electric motor increases. Thermal protection devices protect an asynchronous electric motor from emergency operating modes accompanied by an unacceptable excess of the temperature of their windings. In order to build an indirect system of protection against overheating of the stator windings, a temperature observer has been developed using already available signals in a frequency-controlled electric drive. Simulation studies were performed in Matlab/Simulink application software packages. Simulation studies were carried out on the basis of asynchronous electric motors of the 4A series with a capacity of 30, 75 and 110 kW in the temperature range from 20 °C to 250 °C. As a result of the research, it was found that the error of indirect calculation of the temperature of electric motors, taking into account the correction factor, does not exceed 1 %. The proposed temperature observer can be used to build protections for asynchronous electric drives

The state of the art of high-torque electric motors has been reviewed in this paper. This paper presents a literature review of high-torque density electric machines based on their airgap classifications, which brings a unique consideration to new design ideas to increase torque density. Electric machines are classified into three main groups based on their airgap configuration, i.e., (1) machines with a constant airgap, (2) machines with a variable airgap, and (3) machines with an eccentric airgap. This paper also presents the modeling of a high-torque airgap-less electric motor based on the concept of eccentric airgap. The torque density of this motor has been compared to motors available in the literature review. Among electrical motors with no permanent-magnet, airgap-less electric motors take the lead in terms of torque density, which is almost five times greater than the next motor, “in-wheel for electric vehicle”.

Electric motors are a very vital need in an industry, household and other needs. Electric motors that are often used in an industry are types of induction motors, where the induction machine is an electric motor that is very easy in its maintenance system so that this motor has the highest rating in its use system. In this study, using a single-phase induction motor as a maggot dryer is useful for making the maggot storage period longer and of high selling value. This study aims to protect the single-phase induction motor in the maggot drying system against temperature increase due to prolonged grinding using the DS18B20 sensor. So that the single-phase induction motor is able to work when the motor is unstable at the time of overcurrent. With the installation of the DS18B20 sensor, the single-phase induction motor will stop automatically when the given temperature setting has exceeded the limit set on the sonoff. With the protection system of this single-phase induction motor, it can maximize the performance of the electric motor in the maggot drying process and provide convenience in remote motor control and time setting on and off using the Internet of Things (IoT).

The 3-phase induction motor is an electric motor with a strong, reliable, and easy-to-operate construction, and it is cheaper compared to other types of electric motors, making it widely used by the public. Although this motor is considered reliable, it still has some drawbacks, such as low performance, including starting torque, power factor, and efficiency compared to other types of electric motors. Therefore, research to improve the performance of this motor is ongoing. This paper aims to outline some methods that have been used by previous researchers to improve the performance of induction motors based on literature studies. Some of the methods discussed in this paper include the use of permanent magnets on the rotor, operating the 3-phase induction motor on a single-phase system, developing ferromagnetic materials for the motor, increasing the number of coil phases, and optimizing coil design in the motor. The advantages and disadvantages of using these methods to improve motor performance are briefly outlined.

Abstract With the development of the economy and the deepening of the energy crisis, electric vehicle has now become the hotspot of the global automotive industry. Therefore, as the key part of electric vehicle, the design and research of drive motor has become the focus of attention of engineers and technicians. Because of its simple structure, easy maintenance, high output power, high output torque, wide speed range, and high efficiency, the switched reluctance motor (SRM) has been one of the first choice of electric vehicle driving motors. According to the performance requirements of electric vehicle driving motors, a 3-phase 24/16 pole with rated power of 30 kW switched reluctance motor (SRM) for electric vehicle has been designed in this paper by using Motor-Cad which can be used to optimize the parameters of motor to make the overall structure of the motor more reasonable. In order to reduce the torque ripple of switched reluctance motor, appropriate stator polar arc and rotor polar arc design are used in the motor. To realize the speed control of switched reluctance motor in a wide range, PWM control mode is adopted in this paper, which has fast motor response speed, high power factor and excellent dynamic and static performance. The simulation results show that the performance indexes of the switched reluctance motor meet the design requirements completely.

The aim of this paper is to point out the importance of early diagnostics and assessment of the condition of the electric motor in increasing the reliability and availability of the plant. Electric motors are unavoidable elements in every production process. As the complexity of the process increases, the number of electric motors involved in it increases. By increasing the number of electric motors, the possibility of cancelling and interrupting production increases. It is therefore very important to monitor the situation and detect defects at an early stage so that timely repair or replacement can be planned, without affecting the production process. Modern diagnostic methods that can be used both during the operation of the electric motor, and with the dismounted and dismantled electric motor are presented in the paper. With good organization and testing schedule and a combination of static and dynamic diagnostic methods, the reliability and availability of the plant can be significantly increased. With increased reliability and availability, a reduction in maintenance costs is achieved. In this article, some examples from the author's practice are given, when serious engine defects were discovered. These cases confirm the value of predictive testing to increase reliability of electric motor.

The latest electric train at this time has begun to be widely used linear synchronous motors with permanent magnets as driving locomotives. This permanent magnet has the same function as a conventional synchronous motor which is to produce a magnetic field so that the motor can move linearly. This linear synchronous motor does not have a gear (gear) and axis, but the mechanical motion of this linear motor is synchronous with the magnetic field running. This running magnetic field is produced by the entanglement of the three phases and the arrangement of magnetic poles U, S, U, S. Because the motor is linear synchronous is a high-speed motor, the mechanical speed is the same as the speed of the magnetic field running. So that this motor is capable of producing large thrust compared to the use of conventional motors (DC motors and induction motors) to drive electric rail trains. If the conventional synchronous motor uses a frequency of 50 Hz, then the linear high-speed synchronous motor uses a frequency of 5-50 Hz in changing its speed and this research the efficiency, electromagnetic power (thrust) and thrust force of a synchronous motor will be analyzed. linear according to the frequency selection from 5-50 Hz, to drive the electric train locomotive.

Research on hybrid electric vehicle (HEV) which combined battery based electric motor and conventional internal combustion engine (ICE) have been intensively increased since the last decade due to their promising solution that can reduce global warming. Some examples of electric motors designed for HEV propulsion system at present are dc motor, induction motor (IM), interior permanent magnet synchronous motor (IPMSM) and switched reluctance motor (SRM). Although IPMSMs are considered to be one of the successful electric motor used in HEVs, several limitations such as distributed armature windings, un-control permanent magnet (PM) flux and higher rotor mechanical stress should be resolved.

In the modern oil industry, the vast majority of oil production units are represented by sucker rod pumping units, driven mainly by asynchronous electric motors without using any monitoring, control and regulation means. Studies carried out on such installations show their low energy efficiency and reliability. Therefore, the issue of developing complex electric drives of a new generation based on the use of synchronous valve electric motors is relevant allowing to significantly increase the energy efficiency and reliability of both individual installations and to ensure the creation of "smart" oil field control systems. The paper discusses new technical solutions of the experimental stand which makes it possible to study the energy characteristics of electric drives based on asynchronous and synchronous valve electric motors, as well as allowing to create conditions as close as possible to real field conditions with imitation of the operation of an oil pumping unit of a sucker rod pumping unit. In modern test equipment systems, devices are often used to create a mechanical load on the shaft of the electric motor under study. The system proposed and implemented as such a device is "a frequency converter - load asynchronous electric motor", which has been tested on a stand and has proven to be the best in comparison with traditional circuits using DC motors. But using of a load asynchronous electric motor as part of the test stand has revealed a number of disadvantages: overheating of the electric motor operating in the opposing mode, low accuracy of creating the load torque and the speed of the system's response. The problem of overheating of the load electric motor has been solved by transferring the frequency converter to the direct torque control mode, while a significant decrease in the motor current and stabilization of the temperature regime have been detected. The low accuracy and response speed of the system have been increased by introducing feedback and a PID controller into the stand control system.

Driving electric vehicles by electric motors can result in many unique advantages for dynamic control of electric vehicles. With the superior fast and accurate torque control performance of electric motors, electric vehicles, in particular, can achieve higher levels of safety and handling performance. A simple, effective and efficient anti-skid control method specified for electric vehicles is proposed in this paper by considering the real-world resistance factors. This method is developed on the basis of sensing and regulating a newly defined parameter, namely the ratio of the drive motor torque to the angular acceleration of the wheels, both of which can be easily obtained for electric motors. The monotonic relationship between the slip ratio and the ratio of the drive motor torque to the angular acceleration of the wheels is proved under both acceleration conditions and deceleration conditions, by considering the real-world resistance factors. The simulations and the experimental results show that the ratio of the drive motor torque to the angular acceleration of the wheels can be efficiently used, instead of the slip ratio, in anti-skid control. The results indicate that electric vehicles can achieve high-performance vehicle motion control with more flexible and simplified configurations by using in-wheel electric motors.

Recent research reveals that multi-phase motors in electric propulsion systems are highly recommended due to their improved reliability and efficiency over traditional three phase motors. This research presented a comparison of optimal model design of a six phase squirrel cage induction motor (IM) for electric propulsion by using Genetic Algorithm (GA) and Particle Swarm Optimization (PSO). A six phase squirrel cage induction motor is designed and simulated by ANSYS Motor-CAD. In order to find the best fit method, simulation results are compared and applied to the motors for electric propulsion, considering the influence of design upon the motor performance. The six-phase squirrel cage induction motor is more energy efficient, reliable and cost effective for the electric propulsion compared to the conventional three phase motor. In this study, first the initial parameters of the six phase squirrel cage induction motor have been determined and then these parameters have been compared with optimized values by Genetic Algorithm (GA) and PSO optimization. The motor designed is optimized using efficiency and power losses as the fitness function. The six phase squirrel cage induction motor is designed using ANSYS Motor-CAD and the simulation results were also presented along with two-dimensional and three-dimensional geometry. The result shows that the weight and power loss are reduced to 161 kg and 0.9359 Kw respectively, while the efficiency and power factor are increased to 0.95 and 0.87 respectively when PSO is used. This shows that the result is promising.

The rapid development of technology in this era of globalization has an impact on the development of electric motor technology in Indonesia. There are two types of electric motors based on the voltage source used namely DC electric motor and AC electric motor. Because the use of DC motor or AC motor has not been able to meet the needs, the use of BLDC motor (Brushless Direct Current) is a very appropriate choice. In this research, the design of BLDC Axial Flux motor used a single rotor attached to a neodymium magnet and a stator made of two email wires wrapped together. From testing the motor no-load when the source voltage is 18 V it has an input power of 4,038 W and motor speed of 1513 RPM. While when the source voltage is 24 V has an input power of 8,716 W and motor speed 1606 RPM. As for testing motors with loads when the source voltage is 24 V has an input power of 11,432 W, output power 3,579 W, efficiency 31,311%, motor speed 1098 RPM, mechanical torque 0.031 Nm, and electromagnetic torque 0.099 Nm. Coconut laying on overpressed blade roll results in the motor not being able to provide torque according to load needs, so the speed of the motor will drop, and torque increases. Besides, the greater the voltage of the source then the greater the power and speed of the motor.

The main downhole factors influencing the functioning of the submersible electric motor that rotates the drill bit during drilling of deep oil and gas wells are analyzed. The impact of the temperature of the drilling fluid on the value of the active resistance of the cable cores and the drill pipe in deep drilling conditions has been updated. The results of the analysis of known technical solutions and concepts regarding the possibility of voltage control on the clamps of submersible motors, which would implement its physical measurement in industrial conditions, are presented. A method of analytically calculating the phase voltages on the clamps of the submersible electric motor of the electric drill, which is powered by an electric cable with asymmetric electric resistances of the phases, is proposed. The possibility of practical implementation of a laboratory installation based on the proposed method of calculating phase voltages on the clamps of the submersible electric motor of an electric drill is shown. For the practical implementation of the method of analytical calculation of phase voltages on the clamps of a submersible electric motor, the feasibility of using digital processing of signals from current and voltage transmitters located on the surface during oil or gas well drilling is substantiated. The advantages of the proposed method of controlling the voltage on the clamps of the submersible electric motor of the electric drill are the consideration of the electrical parameters of specific power supply cables obtained as a result of auxiliary measurements, and the possibility of technical implementation on a modern element base. The development and implementation of a device for monitoring phase voltages on the clamps of the submersible electric motor of an electric drill will increase the operational reliability and efficiency of drilling wells with an electric drill, which will reduce their cost.

This research proposes a novel cooling system to minimize the external rotor type of electric motor temperature by installing fan blades (wafters) on the inner housing of the electric motor. Fan blades (wafters) are made by printing using 3D printer technology and using polylactic acid (PLA) as the material. Wafters are then installed on an in-wheel motor with a power of 1500 W, having 48 poles and 52 slots. The study included thermal simulation and experimental techniques to ascertain how fan blades (wafters) affected the electric motor’s thermal properties. The motor rotated at 500 rpm during the experimental test with no load condition. The temperature of the electric motor is known using an infrared thermal imager. Using Ansys Motor-CAD 15.1 software, thermal modeling employs the lumped circuit model approach. Thermal simulation results show almost the same results as the experimental test results. Applying wafters on the in-wheel motor housing significantly reduces the winding temperature by 3.047 °C or experiences a temperature reduction of 4.34%. Using wafters in the in-wheel motor housing also speeds up the stable state temperature of the electric motor by 9 min compared to in-wheel motors without wafters.
