In simple words, the induction motor which uses a squirrel cage rotor is called squirrel cage induction motor. The reason behind the name “squirrel cage” is because of the type of rotor used in these motors. Instant artist download professor. In these type of motors, the rotor is simplest and most rugged in construction. These motors have much higher efficiency than slip ring induction motors. Most of the industries prefer these type of motor due to less maintenance cost, higher efficiency, and their lightweight construction. Let see the construction of squirrel cage induction motor. Squirrel cage induction motor construction Any Induction Motor has main two parts: a Stator and a Rotor.

An induction motor's rotor can be either wound type or squirrel-cage type. Three-phase squirrel-cage induction motors are widely used as industrial drives because they are self-starting, reliable and economical.

The construction of of the induction motor is almost the same as other motors. But the rotor construction differs with respect to the type of motor. Slip ring induction motor is made up from and squirrel cage induction motor is made up from the squirrel cage rotor. Stator The stator is the outer component of the motor which can be seen. A stator is in all the motor only winding on the stator is vary with types of motor.

In squirrel cage induction motor, there is a 3 phase winding on the stator slots. Windings are such placed that they are electrically and mechanically 120 o apart from in space. These windings are either star connected or in delta connected. The winding on a stator is mounted in such a way that it provides low reluctance path for generated flux by A.C current. The insulation between the windings is generally varnish or oxide coated. Now let’s move toward the construction of the squirrel cage rotor.

Squirrel cage Rotor Almost 90% of induction motors are provided with a squirrel cage rotor because of its very simple, robust and almost instructible construction. In this type of motor, the rotor is cylindrical core which is laminated to avoid power losses. Squirrel cage rotor is made up of aluminum or copper bars which are placed parallel to each other and all the bars ( conductors ) are short-circuited with end rings. The rotor conductors and end rings form a complete closed circuit. Here rotor core is laminated to avoid power losses from eddy current and hysteresis. In motor rating up to 100 kW, the squirrel cage rotor is made up from the aluminum cast.

In this type of rotor, conductor bars and end rings are permanently short-circuited so we can’t connect any external resistance in rotor circuit for starting purpose. In previous, we saw we can add external resistance in the rotor in slip ring induction motor. Other parts of motor: A fan is attached to the back side of the rotor to provide heat exchange, and hence it maintains the temperature of the motor under a limit.
