Optimal design of induction motor with multi-parameter by FEM method

Abstract

There are a lot of parameters to improve the efficiency of squirrel cage induction motors. Most of the studies deal with only one parameter at a time. However, Optimization of all parameters are needed to get the most efficient motor. This paper shows that three phase induction motor parameters including rotor slot type, stator slot type, steel sheet and rotor material optimized by using the module Rmxprt in Maxwell. The Results show that 157% increasing torque and 4.1% increasing efficiency are obtained.
