Various methods of starting of synchronous motors are described as follows: From DC Source When dc supply and dc compound motor are available, the synchronous motor is coupled and started by means of a dc compound motor. The...
The four various types of torque associated with a synchronous motor are described below. Four types of torque are, Starting torque It indicates the ability of the motor to accelerate the load. It is also sometimes called...
The armature winding of an alternator is distributed over the entire armature. The distributed winding produces nearly a sine waveform and heating is more uniform. Likewise, the coils of armature winding are not full-pitched, the...
