Description

3 phase synchronous motor

The operation of a typical three-phase synchronous motor can be summarized as follows:

Three-phase AC voltage is applied to the stator windings, producing a rotating magnetic field.

DC voltage is applied to the rotor winding, producing a second magnetic field.

The rotor then acts like a magnet and is attracted by the rotating stator field.

This attraction exerts a torque on the rotor and causes it to rotate at the synchronous speed of the rotating stator field.

The rotor does not require magnetic induction from the stator field for its excitation. As a result, the motor has zero slip compared to the induction motor, which involves mistakes to produce torque.

Synchronous motors typically start as a standard squirrel cage induction motor through special rotor amortisseur windings. Synchronous motors are not self-starting and therefore require bringing the rotor up to near synchronous speed before the rotor DC power is applied. Also, there are two basic methods of providing excitation current to the rotor. One way is to use an external DC source with current supplied to the windings through slip rings. The other method is to have the exciter mounted on the standard shaft of the motor. This arrangement does not require the use of slip rings and brushes.
