Synchronous Motor Working Principle and Construction

Synchronous Motor Working Principle and Construction

Synchronous motor construction is very similar to synchronous generator construction except that most motors are salient-pole machines. Principle and Operation of┬áSynchronous Motor When an induction motor is connected to a three-phase supply, a rotating magnetic field is established; this induces currents in the rotor windings, thereby producing a torque. The rotor can never turn at … Read more

Universal Motor Characteristics, Speed Control and Life

universal motor parts

Universal Motors The universal motor is a special kind of ac series motor that performs almost as well as a dc motor. It delivers a high starting torque, its speed can be adjusted, it is small in size, and it is inexpensive. There are two main differences between dc series motors and universal motors. The … Read more
