What is the slip speed of an induction motor?

The slip speed is the difference between the synchronous and rotor speed of the induction motor. The emf induces in the rotor because of the relative motion, or we can say the slip speed of the motor. So, The rotor current is directly proportional to the induced emf. The torque is directly proportional to the rotor current.
