Principle of AC induction motor
*Changing magnetic field in electromagnet induces current in rods of squirrel cage
*Current in rod, generate their own magnetic fields - oppose magnetic field of electromagnet
*Repulsion of magnetic fields cause the cage to rotate - repeated 100 time a second
Why the majority of motors are AC induction motors
*Cheap
*Simple in design
*Less moving parts - low maintenance
