摘要
根据航空用电动机的性能指标及其要求,利用ANSYS-Maxwell 2D软件建立电动机模型并仿真分析了气隙磁密,削弱了电动机的齿槽转矩。利用ANSYS-Mechanical软件对优化设计后的电动机噪声场进行仿真分析。根据永磁无刷直流电动机电路模型以及航空电动机的机电动作器控制原理图,对样机施加激励,测定电动机的声压级,仿真结果较好。仿真结果和测试值较为接近,验证了仿真结果的准确性,对航空用电动机的性能提升具有一定的参考意义。
According to the requirements of the aviation motor performance index,using ANSYS-Maxwell 2D software designed motor model and the simulation analysis of the air gap flux density,weakened the cogging torque of the motor. By using ANSYS-Mechanical software to optimize design of motor noise field simulation analysis.According to the model of the permanent magnet brushless DC motor circuit and mechanical and electrical motion control principle diagram of the aviation motor,applying incentives for prototype,determination of the sound pressure level of the motor,the simulation results were good. The simulation results and the test value was relatively close,the accuracy of the simulation result was verified for aviation motor performance has a certain reference significance.
