it is the difference between the synchronous and asynchronous
speed of a induction motor
What is slip in ac motor?
Slip is the difference between the rotor speed and synchronous speed, expressed as a percentage of the synchronous speed (it can also be expressed as a per unit value). So when the rotor is stationary, its slip is 100% (or 1); if it were able to achieve synchronous speed (it can't!) then is slip would be 0% (or 0).
What are the different types of AC motor?
slip ring, synchronous, and squirrel cage induction
motors....
