摘　　要：测量小功率异步电动机的M-S曲线时,磁粉测功机是作负载用,其机械特性要求类似于风机特性。指出了对磁粉测功机的固有特性进行改造的方法,并在异步电动机的M-S曲线测量上的应用。When the M - S curve of a low power asynchronous motor was measured, the powder dynamometer acted as a load, and its mechanical characteristics were required like a blower. A way to improve the mechanical characteristics of a magnitic powder dynamometer was given out in this anticle, and its application of this way in measuring M - S curve of a a- synchronous motor was introduced.

关 键 词：磁粉测功机 机械特性 异步电动机
