Abstract (sommario):

An electric motor is an electro-magnetic device that converts electrical energy into mechanical energy. This mechanical energy is used to, for example, rotate a pump impeller, fan or blower, drive a compressor, lift materials, etc. Electric motors are also used at home (mixers, electric drills, wind fans) and in industry. Electric motors are sometimes called the "workhorse" of industry because it is estimated that they use about 70% of the industry's total electrical load. And at this time the power from the power source, namely PLN (State Electricity Company) often changes in voltage.

Abstract (sommario):

A three-phase induction motor absorbs the most electric power among other electrical loads. Therefore, three-phase induction motors are the primary electric motors used in industrial applications thanks to their simple construction and easy operation, as well as low cost and low maintenance costs. Efficiency is a critical parameter that characterizes an induction motor as a traction motor. The traction motor is defined as the engine's effectiveness in converting electrical power at its input into mechanical energy by rotating torque on its axis. One way to analyze the efficiency is to use test

Currently, induction motors are widely used in industry because have a high potential for the efficiency improvement. Therefore, a topic of interest to the industry is to reduce the energy consumption of induction motors, as they represent almost half of the total electrical energy consumption in the world. The energy consumption of electric motors can be reduced by using motors that are more efficient and by using power converters to feed the motors, thereby enabling accurate control according to the load.

Most of wheel aerators are driven by electric motors than diesel engines as their easy operations. The electric motors need high electrical energy to drive wheel aerators along day and night. The common type of motor used is Alternating Current (AC) or induction motor, however Brushless Direct Current (BLDC) motor has potential electrical energy saving which need to be explored. This study objectives to find out performance of BLDC and AC motor as paddle

Abstract (sommario):

This paper provides an overview of the Linear Transportation System (LTS) and focuses on the application of a Linear Induction Motor (LIM) as a major constituent of LTS propulsion. Due to their physical characteristics, linear induction motors introduce many physical phenomena and design constraints that do not occur in the application of the rotary motor equivalent. The efficiency of the LIM is lower than that of the equivalent rotary machine, but, when the motors are compared as integrated constituents of the broader transportation system, the rotary motor’s efficiency advantage diminishes e

Abstract (sommario):

Electric induction motors are one of the most important and widely used classes of machines in modern industry. Large motors, which are commonly process-critical, will usually have built-in condition-monitoring systems to facilitate preventive maintenance and fault detection. Such capabilities are usually not cost-effective for small (under ten horsepower) motors, as they are inexpensive to replace. However, large industrial sites may use hundreds of these small motors, often to drive cooling fans or lubrication pumps for larger machines. Multiple small motors may further be assigned to a sing

Linear motors have been widely used in industry and transportation applications. Conventionally, linear motors are supplied by the long power cables or sliding contacts. Insufferable defects of these supply methods are friction, sparks, risk of electric shock, inflexible, and high maintenance cost. Movable contactless power transfer (MCPT) system is an alternative proposal for supply of linear motors. MPCT is based on Amperes and Faradays Laws, uses an alternating magnetic field to deliver electrical power across air to load without physical contact [.
