Squirrel Cage induction motors find wide applications in industries and in homes. Their rugged constructions and low maintenance makes them the motor of choice for many requirements.
- Lathes and turning equipment
- Industrial Drives
- Fans and Blowers
However, the downside of squirrel cage motors is that they draw a very heavy current when switched on due to the absence of back-emf. Hence, they require special starters.
They also have low starting torque. Hence, they are seldom used in applications such as lifts and cranes.
Another disadvantage of the squirrel cage motor is the poor speed control. However, with the advent of Variable Frequency drives, this disadvantage has been overcome.
