Advantages and disadvantages of squirrel cage induction motor

Squirrel cage induction motor is widely used in industries this is the reason this kind of three-phase induction motor which uses as squirrel cage motor is known as the squirrel cage induction motor. This motor is very robust in construction and also very cheap. Squirrel cage induction motor consists of part like stator, rotor. Stator which is a stationary part and rotor which is a rotating part. Let us have a deep insight into the pros and cons of squirrel cage induction motor to know more about it. 

Advantages of squirrel cage induction motor :

  • Squirrel cage induction motor is cheaper in cost compared to slip ring induction motor.
  • This motor required less maintenance as compared to the slip ring motor.
  • Rugged construction.
  • Generate less heat.
  • Squirrel cage motor is better cooled compared to slip ring induction motor.
  • Squirrel cage motors operate at nearly constant, high overload capacity, and operates at better power factor.
  • Squirrel cage motor is explosion-proof due to the absence of brushes slip ring and brushes which eliminates the risk of sparking.
  • Squirrel cage motor operates at a nearly constant speed, high overload capacity, and operates at a better power factor.
  • Squirrel cage induction motor requires less conductor material than slip ring motor, hence copper losses in squirrel cage motor are fewer results in higher efficiency compared to slip ring induction motor. 

Disadvantages of squirrel cage induction motor :

  • Poor starting torque.
  • High starting current.
  • Speed control is not possible in a squirrel cage induction motor., in short, no speed regulation.
  • Sensitive to change in supply voltage.
  • More sensitive to the supply voltage regulation fluctuations.
  • Total energy loss during stating of squirrel cage motor is more compared to the slip ring motor.
