ROTOR:
(i) squirrel -cage rotor
(ii) phase-wound or wound-rotor
90% of Induction Motor are squirrel cage type due to this type of rotor has a easiest and the most rugged construction and is almost indestructible. Rotor having of a cylindrical laminated core with parallel slots for carrying rotor conductors. Rotor bars are enduringly short circuited on themselves;
