Starting Methods of Synchronous Motor
The starting methods of the synchronous motor are damper winding, external prime mover( DC or induction motor), VVVF method, and slip ring induction motor start
Machines
An electrical machine converts mechanical energy into electrical energy or vice versa. The transformer is also an electrical machine which transform the voltage without changing the frequency. We will discuss about the;
- DC Motor
- DC generator
- Induction Motor
- Transformer
- Electrical drives
- Alternator or synchronous generator
Applications of Synchronous Motor
Synchronous motors are used mainly for power factor corrections, voltage regulation, and constant speed- constant torque applications. Squirrel cage induction motors are the preferred choice
Synchronous Motor Construction and Working Principle
The synchronous motor construction is similar to that of a synchronous generator. A synchronous motor is a type of electric motor that has two separate
What is a Distribution Factor? Definition, Formula
