Synchrnous motor is a constant speed motor but induction
motor is not an constant speed motor but synchronous motor
cannot be used for variable speed purpose....

Answer / sumit

the difference between induction and syncronous motor is
induction motor never run in syncronous speed but
synchronized motor run always in syncronous speed.so
induction motor is call asyncronous motor

Answer / iamdon

These are the differences between Induction
motor and synchronous motor
1)Induction motor always runs at speed less than
Synchronous speed where as synchronous motor always
runs at synchronous speed.
2)Induction motor has AC winding on rotor where as
synchronous motor has DC field winding on rotor.

Answer / 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.
