摘要
脉振磁场永磁低速同步电动机是一种新结构原理的永磁同步电动机，能够实现自起动。但随着负载转动惯量及载荷增大，起动困难，甚至失败。然而，一定间隙与弹性环节的存在，能改善电动机带载起动特性。为此，本文从理论和实验两方面研究了该连接方式下脉振磁场永磁低速同步电动机的起动特性。
Pulsating magnetic field PM low speed synchronous mot or is a type of PM synchronous motor with novel structure and principle, which c an start by itself. But, with the load inertia and torque increase, the starting becomes difficult, even fail. However, it is noticed that the starting capabili ty can be improved if a certain clearance and elasticity exist between motor and loads. So, the starting characteristics of pulsating magnetic field PM low spee d synchronous motor under this condition are studied through theory and test.
