在对同步电动机失步的危害性及电机失步后的运行特征进行认真分析的基础上，利用微机作信息处理手段，提出了一些失步保护措施，使电机能在失步后不停机而自动进行带载重整步以保证生产中工艺流程的连续性。

Based on an analyses to the characteristics of operation of synchronous motor being out of step,and its harmfulness with the help of computers. Some protection measures have been presented here. These protecting measures to be taken can make a motor contin ually running with load while the motor is out of step,at the same time the synchronization of the moter can be restored itself.This can not only avoid harms because of motor being out of step but also guarante the continuity production procedure.
