Abstract:

In recent years, due to growing environmental awareness regarding global warming, green cars, such as hybrid electric vehicles, have gained a lot of importance. With the decreasing cost of rare earth magnets, brushless permanent magnet motors, such as the Interior Permanent Magnet Motor, have found usage as part of the traction drive system in these types of vehicles. As a design issue, building a motor with a performance curve that suits both city and highway driving has been treated in this thesis as a multi-objective problem; matching specific points of the torque-speed curve to the desired

Abstract:

The permanent magnet synchronous machines have been attracting more and more attention due to the advantages of high torque density, outstanding efficiency and maturing technologies. Under the urges of mandatory energy efficiency requirements, they are considered as the most potential candidates to replace the comparatively low-efficient induction machines which dominate the industrial market. However, most of the high performance permanent magnet machines are based on high cost rare-earth materials. Thus, there will be huge demands for low-cost high-performance permanent magnet machines.

Abstract:

This work presents an initial rotor position estimation method for low saliency interior permanent-magnet synchronous motor (IPMSM) drives. The method injects signals into the stationary alpha-beta frame of the motor and substitutes the injected signals into the stationary alpha-beta frame model of the motor to solve for the rotor position. In particular, the method injects specific signals into the motor to eliminate the rotor-position-independent terms while keeping the rotor-position and motor-saliency dependent terms in the motor model. As a result, the rotor-position and motor-saliency de

As drive losses are a combination of the IPMSM losses and the inverter losses, this thesis is mainly divided into two parts: the first part deals with minimising the copper and iron losses of the IPMSM with due account of machine parameters variations and the voltage drop across the stator winding resistance. A new losses minimisation algorithm (LMA) which considers these issues is presented in this research. A comprehensive off-line simulation study

Abstract:

Interior permanent magnet synchronous motor (IPMSM) has been widely used in hybrid electric vehicles (HEVs) since the high power density and efficiency. However, the primary drawback of IPMSM is the demagnetization phenomenon caused by the permanent magnets. Modeling of the demagnetization fault are important in developing and designing a protection system for the traction on HEVs, thus, an efficient and accurate IPMSM model for demagnetization fault simulation is necessary. By using the conventional dq0 IPMSM model, the current indicators of demagnetization fault are affected by noise which w

At first, the 4 poles and 24 slots interior permanent magnet synchronous motor used in this article will be performed with magnetic flux and finite element analysis so as to verify the characteristics of the motor. Meanwhile, two dimensional finite element software Maxwell 2D will be used to construct the magnetic flux analysis model for the motor, and the mathematical calculation software Matlab will be used to calculate the characteristic parameters of the motor. Finally, the above two results will be co

碩士<br>國立成功大學<br>系統及船舶機電工程學系<br>102<br>This thesis presents the design of an interior permanent magnet synchronous motor (IPMSM) for electric scooter (ES) application. The required ES can cruise for an average distance 100 km at 50 km/h or 60 km at 80 km/h in one charging time. Therefore, the ES requires a traction motor possessing high-power density, high efficiency, wide operating range and cost-effective. For these purposes, an IPMSM is designed and analyzed. Firstly, the dynamics behavior of ES is investigated. From this, the specifications of the electric motor such as torque, speed and po

碩士<br>國立臺灣大學<br>機械工程學研究所<br>107<br>This thesis proposes an on-line inductance estimation for interior permanent magnet synchronous motor (IPMSM) to maximize the torque output performance. On the basis, high frequency voltage injection is developed for on-line inductance estimation to improve the maximum torque per ampere (MTPA) control and the maximum torque per volt (MTPV) control performance. It is shown that the torque output is increased during the full load operation in an IPMSM under the flux saturation. Comparing to model-based inductance estimation, the proposed injection based inducta

Abstract:

Throughout the years Hybrid Electric Vehicles (HEV) require an electric motor which has high power density, high efficiency, and wide constant power operating region as well as low manufacturing cost. For these purposes, a new Interior Permanent Magnet Synchronous Motor (IPMSM) with brushless field excitation (BFE) is designed and analyzed. This unique BFE structure is devised to control the amount of the air-gap flux for the purpose of achieving higher torque by increasing the air-gap flux at low speed and wider operating speed range by weakening the flux at high speed.
