Induction Motor

InductionMotor is an electric transformer with a magnetic circuit separated by an air gap into two movable portions carrying the primary and secondary windings. Secondary currents are created by induction rather than being supplied by a dc exciter or other external power source. Types of induction motor are wound rotor and squirrel cage.

Induction motors have National Electric Manufacturers Association (NEMA) specifications.
