synchronous motor
Description:
The fundamental operating principle is similar to that of a synchronous motor with a high number of pole pairs. Asynchronous machines are subdivided into slip ring rotors, squirrel cage rotors and single-phase asynchronous motors. A field that lags behind the main field is needed to start single-phase asynchronous motors.

同步电机
Description:
同步电机结合使用旋转磁场产生的两种手段 - 定子的三相绕组和转子。 同步电机主要用作发电厂的发电机，可以输送约高达 1700 MVA 的额定功率。分为旋转磁场发电机和固定磁场发电机，但固定磁场发电机发挥的作用较小（应急电源系统例外）。 与异步电机相反，同步电机的旋转磁场和转子同步运行。其速度由定子频率和极对数来确定。它不是扭矩的函数。而与异步电机相同，可以使用频率转换器控制速度。除了用作发电机和电动机，同步机也可以用作移相器。虽然在这种情况下，额定功率为 $P=0$ ，产生无功功率。这种运行模式可用于无功功率补偿。
