Multi-objective optimization design of permanent magnet synchronous motor based on differential evolutionary algorithm

In this paper, a multi-objective optimization design method for permanent magnet synchronous motor based on differential evolution algorithm is proposed. Taking the motor quality and motor efficiency as the optimization objectives, and taking the power, motor outer diameter and pulsating torque as the constraints, the optimization model of permanent magnet synchronous motor is established, and the motor is optimized and designed based on differential evolution algorithm. Compared with the traditional response surface method, the proposed method has stronger global search capability, better robustness, and handles nonlinear multi-objective optimization problems better.
