摘要
稀土永磁同步电动机具有效率高、功率因数高的特点,是一种高效节能产品。但是,由于转子磁路结构不对称,以及永磁体激磁效应,使得启动过程比普通异步电动机复杂得多。如果转子磁路结构设计不合理,稀土永磁同步电动机启动过程将卡在非同步转速状态,本文结合样机实测的启动过程转矩M-转差率S曲线特点,对稀土永磁同步电动机启动特性进行分析。
High efficiency and high power factor are characteristic of rare earth and permanent magnetism and synchronous motor.lt is a energy saving product.But,since the structure of magnetic circuit of the rotor is asymmetrical,and there is the excitation effect of permanent magnet,the course of starting be more complex than ordinary asynchronous motor. If the rotor structure of magnetic circuit be design not reasonable, the course of starting of the rare earth synchronous and permanent magnetism motor will block i...
