摘　　要：某些特殊环境下应用的伺服电机具有转矩性能平稳、速域宽的特点,对电机低速下的转矩平稳性及高转速下的磁场气隙波形正弦性设计提出了严苛的要求,针对某款永磁同步伺服电机,分别从转矩特性、气隙磁密和漏磁系数三个方面对比分析永磁体表贴式、Ⅰ型内置和Ⅴ型内置三种转子拓扑结构,并以转矩性能及空载反电势波形正弦性为优化目标进行伺服电机的优化设计和样机制作,实物测试结果与仿真结果吻合,为高平稳性、宽调速伺服电机拓扑结构选择、性能优化设计提供依据。Servo motors used in certain special environments have the characteristics of stable torque performance and wide speed range,which puts forward strict requirements for the torque stability of the motor at low speed and the sinusoidal design of the magnetic field air gap waveform at high speeds.This paper compares and analyzes three rotor topologies of permanent magnet surface mounted,I type built-in,and V type built-in servo motors in terms of torque characteristics,air gap magnetic density,and magnetic leakage coefficient.The optimization design and prototype production of the servo motor are carried out with the optimization objectives of torque performance and sinusoidal no-load back EMF waveform.The physical test results are consistent with the simulation results,and provide a basis for the topology selection and performance optimization design of servo motors with high stability and wide speed regulation.
