Synchronous motor starting methods: Frequency control, Damper winding & more

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

Synchronous Motor: Working principle, Starting methods & Types

synchronous motor

A Synchronous motor is a type of AC motor which runs at a constant speed, known as synchronous speed. The rotor in a synchronous motor always maintains synchronism with the rotating magnetic field of the stator. Even the load variations do not alter the motor’s synchronism. Hence, synchronous motors are used in constant speed applications. … Read more
