Whereas, the rotor is at the stationary condition. Now, Stator will have a rotating magnetic field revolving around. Let us consider, a stator has given with 3-phase supply.Thus, two situations occur at this moment, poles of the stator winding that revolves (i.e., NS – SS) and a pair of rotor poles that are stationary (i.e., NR – SR). The direct (or zero frequency) current supplied in the rotor however will produce a Constant Magnetic Field.

Here the exciting coil is connected in series with two slip wings. In synchronous motor, the rotor can be sub-classified into two parts: salient pole type and non-salient pole type. Rotor rotating speed is the same as the speed of the magnetic field. The rotor is the rotating part of the synchronous machine, to be more simple it is a rod-like type. The armature winding in the stator also receives power from a 3-phase supply. Every gap or surface of the core is insulated in order to prevent the flow of eddy current. These two parts are:- (i) A StatorĪ stator is a cylindrical core having a number of slots where 3-phase armature winding is adjusted into it.

There are main parts of a synchronous motor (like an alternator). It is mainly an alternator being operated as a motor. Construction of Synchronous MotorĪ synchronous motor is an electrical machine that runs at synchronous speed (constant speed) and converts electrical energy into mechanical energy. However, it is not commonly used as it has different properties which doesn’t meet much demand. It is to be noted, that the synchronous motor is a 3-phase motor and its frequency remains constant due to which it obtain synchronized speed (constant speed). The synchronous motor runs at synchronous speed (i.e, Ns= 120f/P).
