Construction Of Synchronous Motor

Synchronous motor and induction motor are the most widely used types of AC motor. Construction of a synchronous motor is similar to an alternator (AC generator).A same synchronous machine can be used as a synchronous motor or as an alternator. Synchronous motors are available in a wide range, generally rated between 150kW to 15MW with speeds ranging from 150 to 1800 rpm.

Where, N s = synchronous speed, f = supply frequency and p = number of poles. As we can see from the equation, the synchronous speed depends on the frequency of the supply and the number of poles.

Synchronous Motor Construction. Stator. The stator has a three-phase winding and is of the same type as that in an alternator or induction motor. When this winding is energized with AC it produces a magnetic flux that rotates at a speed called the synchronous speed.

Synchronous Motor Working Principle and Construction. Principle and Operation of Synchronous Motor. When an induction motor is connected to a three-phase supply, a rotating magnetic field is established; this induces currents in the rotor windings, thereby producing a torque.

Synchronous Motor. The synchronous motor doesn’t rely on induction current for working. In these motors, unlike induction motor, multiphase AC electromagnets are present on the stator, which produces a rotating magnetic- field.Here rotor is of a permanent magnet which gets synced with the rotating magnetic- field and rotates in synchronous to the frequency of current applied to it.

The construction of a synchronous motor is basically similar to the alternator of rotating magnetic field type. It consists of two main parts, stator, and rotor. Stator : (i) It is a stationary part of a machine. (ii) The armature winding is placed on the stator and so it is called stator winding.

14-09-2020· Electric motor - Electric motor - Construction of induction motors: The stator frame consists of laminations of silicon steel, usually with a thickness of about 0.5 millimetre. Lamination is necessary since a voltage is induced along the axial length of the steel as well as in the stator conductors. The laminations are insulated from each other usually by a varnish layer.
