What is the difference between induction motor and the
Synchronized one?

Answer Posted / ln sahu db power ltd.

3 phase induction motor is self starting device . its
relative speed between stator and rotor field not equal to
zero. while in synchronous motor its average torque is zero,
i.e. relative speed between stator and rotor field is zero
.hence it is not a self starting device.
