An induction motor or 3 stage induction motor can be an AC Three Phase Motor electric electric motor in which the electric energy in the rotor had a need to generate torque is obtained by electromagnetic induction from the magnetic field of the stator winding
An induction motor which connects with a 3-phase supply called 3-stage induction motor. Example fans,blowers, cranes,traction .It is a ac electric motor. The main drawback of DC motors may be the presence of commutator and brushes, which require regular maintenance and we can’t use DC engine in explosive and filthy environment. But induction motors are cheaper,tough,lighter,smaller,require less maintenance and will use in dirty and explosive environment. Slide s is the imp factor in this type of motor.
There are 2 types of IM.
Squirrel cage IM
Slip ring IM
There are various starting and braking condition.
Important starting methods are
Star-delta starter
Auto transformer 
starter
Ac voltage controller starter
Rotor resistance starter
Important braking methods are
Regenerative braking
Plugging or invert voltage braking
Dynamic braking
But one thing quickness control technique of induction motor is important
Pole changing
Stator voltage control
V/f control
Slip power recovery
Rotor resistance control
