Summary:The direct drive permanent magnet toroidal torque motor for aviation and ship has strict performance requirements on cogging torque ripple, motor weight and efficiency. Aiming at the optimization design of permanent magnet ring torque motor (PMRTM), a multi-objective optimization design method based on response surface method is proposed. By analyzing the sensitivity of different structural parameters to the motor performance, the main parameters are selected as the optimization variables, and the response surface models are constructed according to the Kriging proxy model algorithm. Finally, the Parato optimal solution of cogging torque and efficiency is obtained through genetic algorithm. It is convenient to get the design scheme with small cogging torque and high efficiency by using this method. The finite element simulation results show that the optimization algorithm is feasible and effective.
