摘　　要：掌握负载杂散损耗的实测数据,对于永磁同步电动机的设计有重要意义,但目前业内尚没有公认的有效方法测取这一数据。在异步电动机杂散损耗测量方法的基础上,文章推导出一种适用于永磁同步电动机负载杂散损耗测量的方法,并通过试验验证,证实了该方法的可行性和准确性。Measured data of load stray loss is extremely crucial to permanent magnet synchronous motor design.But there is no recognized effective method to measure this data in motor industry.Based on the measuring method of stray loss of induction motor,this paper deduces a method suitable for permanent magnet synchronous motor.The feasibility and accuracy of this method are verified by tests.
