Optimization of asynchronous motor with Taguchi method based on Finite Element Analysis

Abstract

In order to study the operation process of the motor and improve the operating performance of the motor, this paper performs finite element simulation of the three-phase asynchronous motor and optimizes the initial design by using the Taguchi method. Firstly, a three-phase asynchronous motor model is established with the voltage, current, torque, flux linkage, distribution of the flux lines and magnetic induction intensity of the motor under rated conditions is vertified by Finite Element Analysis (FEA), and the total accuracy reaches 92%. Then, the parametric simulation of the stator and rotor cogging parameters and stator and rotor parameters is carried and the sensibility of different parameters on the motor torque is obtained. The rotor cogging parameter Hs01 and stator cogging parameter Hs0 had the highest sensitivity, which were 75% and 16%, respectively. Finally, the Taguchi method was applied to optimize the torque of the motor, and the torque was increased by 9.5%.
