Design and Performance Optimization of Premium Induction Motors, Edition 1

International Efficiency (IE) is an up-and-coming phenomenon that refers to how energy-efficient motors are. The International Efficiency 1 and 2 classes are very well developed, while IE4 has been in the pipeline. The classification technique can improve the energy efficiency of the motor even more. The motor's baseline energy performance is determined using these specs.

The goal of this project is to conduct a conversion study of an induction motor of efficiency class IE2 to class IE3/IE4. The induction motor following International Efficiency 60034- 30-1 standard's efficiency ratings is considered. The research will be carried out using dedicated computation programs, with experimental validation utilizing Altair's Fluxmotor software.

First, motor efficiency, rating, and application of the motor are established and necessary calculations are performed. Then, a motor reference torque-speed map is constructed based on the planned motor performance, along with the division of power losses and the application's power rating, once the efficiency has been determined. The calculated values are then fed into the Altair Flux motor software and a motor of IE2 efficiency class is obtained. This IE2-rated motor is then optimized to reach IE3 and IE4 standards. The performance parameters such as efficiency, speed, torque, temperature and flux distribution, etc. are obtained for various dimensions and structures of the motor. The design optimization technique achieves motor characteristics that adjust as much as feasible to the defined performance, and later adjust it to the characteristics of a water pump or an electric car. The results provide the IE2, IE3 and IE4 standard Induction motor design.
