Synchronous Motors Manufacturers

The synchronous motors are specifically designed to maintain constant speed, with the rotor synchronous to the rotating field. It requires a separate source of DC for the field. It also requires special starting components. These include a salient-pole field with starting grid winding. The rotor of the conventional type motor is essentially the same as that of the salient-pole AC generator. The stator windings of induction and synchronous motors are essentially the same. It differs from the induction motor in several ways. If supplied with proper voltage, a dc generator operates satisfactorily as a dc motor, and there is practically no difference in construction and rating between the two. The rotating fields are generally of the salient pole type.
