为避免同步电动机失步运行的情况，提出了一种基于同步电动机功角测量的新的失步保护方案。
This paper analyzes how the non - probe exciter of synchro motor works and functions on the basis of the no.
在一定控制脉冲频率下，步进电动机可能出现振荡与失步现象，严重影响步进电动机的运行，要严格防止这种情况发生。
When stepping motor works in some pulse frequency, it may have the problem of oscillation and miss of synchronization, so it should be avoided at full steam.
即实现了电动机高精度运行，又解决了同步电动机的易失步问题。
Motor running high-precisely and avoiding loss of synchronism are both realized.
