一种新型交流永磁伺服电动机齿槽转矩性能测试装置的构建及应用研究

摘要

Both AC permanent magnet servo motor's inherent characteristics and the cogging torque influence the motor' s low speed property and high precision positioning,and in the development stage of the motor,having the cogging torque-related electromagnetic design and assessment considered becomes necessary.According to practical application in a company,the proposed permanent magnet servo motor's cogging torque testing device and methods were discussed and compared,including their applicability and feasibility.%由于交流永磁伺服电动机的固有特点,存在齿槽转矩,影响电动机的低速性能和高精度定位,因此在研发阶段对电动机齿槽转矩相关的电磁设计和测试评估十分必要.根据在某公司的实际应用,对所构建的这种新型永磁伺服电动机齿槽转矩测试装置进行了详细论述,同时通过对现有齿槽转矩测试方法与装置的对比分析,系统地阐述了所述测试装置的实用性与可行性.
