Question

Difference between induction motor and synchronous motor

Answer 1

ANSWER
.........

INDUCTION MOTOR CAN GENERATED AN ELECTRICITY

SYNCHRONOUS CANNOT GENERATED A ELECTRICITY

Answer 2

Induction motor: Stator winding is similar to that of a synchronous motor. It is woundfor a specific number of poles.A squirrel cage rotor or a wound rotor can be used. In squirrel cage rotor, the rotor bars are permanently short-circuited with end rings. In wound rotor, windings are also permanently short-circuited, hence no slip rings are required.Induction motorDifference in working*.Synchronous motor: Stator poles rotate at the synchronous speed (Ns) when fed with a three phase supply. The rotor is fed with a DC supply. The rotor needs to be rotated at a speed near to thesynchronous speed during starting. If done so, the rotor poles get magnetically coupledwith the rotating stator poles, and thus the rotor starts rotating at the synchronous speed.
