Synchronous motor starting methods

There are three main synchronous motor starting methods: The first is by reducing the supply frequency, the second is by using an external motor, and the last is to start with damper windings. The external motor drives the synchronous motor shaft. It can either be a pony motor, a DC motor, or an Induction motor. … Read more
