Working of Synchronous Motor - your electrical guide

As the three-phase AC supply is connected to the stator winding, a rotating magnetic field (RMF) is produced. This field rotates at the synchronous speed N s.The two poles produced are N 1 and S 1, as shown in the Figure. These stator poles (N 1 and S 1) rotate in the air gap between stator and rotor at synchronous speed in the clockwise direction.

Rotor : Construction, Working Principle,Types and Its

Construction and Working Principle of a Rotor In a three-phase induction motor, once an AC is applied to the rotor then the windings of stator strengthen to generate a rotary magnetic flux. The flux generates a magnetic field in the air gap among the stator & the rotor to induce a voltage for generating the current throughout the bars.

Types and Amazing Appliions of Induction Motor

4/6/2020· Three-phase AC induction motors have various uses in commercial and industrial appliions. The two types of three-phase induction motors are- squirrel cage and slip ring motors. The features which make the squirrel cage motors widely applicable are mainly their simple design and rugged construction.

The vector diagram for the split phase induction motor is shown in the Figure B. As the winding resistance of starting winding is high, the angle between voltage and current I s is small. Similarly the inductance of the running or main winding is high therefore the angle

Synchronous motor - construction and working |

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.

Single Phase Induction Motor | Electrical4U

25/10/2020· The construction of the rotor of the single-phase induction motor is similar to the squirrel cage three-phase induction motor. The rotor is cylindrical and has slots all over its periphery. The slots are not made parallel to each other but are a little bit skewed as the skewing prevents magnetic locking of stator and rotor teeth and makes the working of induction motor more smooth and quieter
