squirrel cage induction motor working principle

In squirrel cage induction motor, rotor consist of copper bars instead of windings. In stator, there are 3phase windings where 3phase supply is given to it.

A squirrel-cage induction motor (SCIM) - is an asynchronous electric motor, in which the rotor is made with a short-circuited winding in the form of a squirrel cage [1] . Induction motor construction, The three-phase induction electric motor, as well as any electric motor, consists of two main parts - the stator and the rotor.

Induction motor is a machine that simply operates on the induction type principle. It was invented by the scientist Tesla who earlier conducted several experiments on the working of the alternating current systems. Later, several experiments have been done to improve the performance of this type. This led to the inventions of the induction type

Its rotor coil is cast aluminum and shaped like a squirrel cage, so it is called a "squirrel cage motor". These motors are a specific kind of 

The principal advantages of the squirrel-cage induction motor are its simplicity of design and robust construction. Its torque/speed and current/speed characteristics are such that, on

Principle of Squirrel Cage Induction Motor: When the stator winding is supplied, the rotating magnetic field is set. This is the motion of the rotating magnetic field called synchronous

The division of the rotor current between the cages is determined by their relative impedance (reactance). Therefore, at the start, comparatively only small 

Principle of Squirrel Cage Induction Motor: When the stator winding is supplied, the rotating magnetic field is set. This is the motion of the rotating magnetic field called synchronous speed. This rotating magnetic field excites the voltage in the rotor bar so that a short circuit current is passed through the rotor bar.

29/10/  · Working principle of Squirrel cage induction motor Squirrel cage induction motor. A squirrel cage induction motor will be composed of the squirrel cage windings. Aluminum bars would be molded on the slots and they will be short-circuited at the end rings. In order to reduce noise, the bars would be slanted in a small rotor.

Squirrel induction motor working is based on the principle of electromagnetism. When the stator winding is supplied with a three-phase AC, it produces a rotating magnetic field (RMF) which has a speed called synchronous speed. This RMF causes voltage induced in the rotor bars. So, that short-circuit current flows through that.
