Construction Working principle of Synchronous Motor

Consider a three-phase synchronous motor, whose stator is wound for 2 poles. The two magnetic fields are produced in the synchronous motor by exciting both the windings stator and rotor with three-phase a.c. supply and d.c. supply respectively. When the three-phase winding is excited by a three-phase a.c. supply then the flux produced by the three-phase winding is always of rotating type.

An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field, and an inside rotor attached to the output shaft producing a second rotating magnetic field. The rotor magnetic field may be produced by permanent magnets, reluctance ...
