永磁同步电机牵入同步分析

Pull-torque Analysis of Permanent Magnet synchronous Motor

从永磁同步电动机的数学模型着手．推导了永磁同步电动机的起动转矩的数学表达式，并由此分析了在牵入同步这个复杂过程的中起作用的转矩．

This article deduces the pull-in torque expression of permanent magnet synchronous motor from its mathematical model and analysis its funaction during its pull-in process.
