Induction Motor:
Almost 70% of the machines used in industries now a days are 3 phase induction motors. It works on the principle of induction where electro-magnetic field (emf) is induced in to the rotor conductors when rotating magnetic field of stator cuts the stationary rotor conductors. As the ac power is used in generation, transmission and distribution induction motors occupied significant place in industrial drive applications and out rule the dc motors which were earlier used for industrial applications. Induction motors are of two types based on the construction: Squirrel cage induction motor and slip ring induction motors. Squirrel cage induction motors are widely used in motor and drive applications. Some of the advantages of induction motors compared to dc motors and synchronous motors. Also disadvantages of induction motors compared to other motors are also given below:
Induction Motor Advantages:
These advantages in induction motors make them more prominent in industrial and domestic applications.
Induction Motor Disadvantages:
Some of the disadvantages of induction motors compared to dc motors and synchronous motors are:
These are some of the disadvantages associated with induction motors
