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.
