Key Terms

Induction Motor
An electric motor that operates on the principle of electromagnetic induction.

Example: Induction motors are commonly used in fans and pumps.

Rotor
The rotating part of an electric motor that interacts with the magnetic field.

Example: The rotor in a squirrel cage motor is made of conductive bars.

Stator
The stationary part of an electric motor that produces a magnetic field.

Example: The stator surrounds the rotor in an induction motor.

Electromagnetic Induction
The process of generating electric current from a changing magnetic field.

Example: Electromagnetic induction is the principle behind how generators work.

Efficiency
A measure of how effectively a motor converts electrical energy into mechanical energy.

Example: Higher efficiency means less energy waste in motors.

Conductive Bars
Metal bars in a squirrel cage rotor that conduct electricity and create magnetic fields.

Example: The conductive bars are shorted at both ends in a squirrel cage rotor.
