The slip of an induction motor is the difference between the rotor speed and the synchronous speed. The slip is directly proportional to the load torque and inversely proportional to the synchronous speed. The core loss component is a small percentage of the total loss in an induction motor. It does not have a significant impact on the slip.
The following are the factors that affect the slip of an induction motor:
Synchronous speed: The synchronous speed is the speed at which the rotating magnetic field of the stator would rotate if there were no rotor. The synchronous speed is determined by the frequency of the stator voltage and the number of poles in the stator.
Rotor speed: The rotor speed is the speed at which the rotor actually rotates. The rotor speed is determined by the load torque and the slip.
Load torque: The load torque is the torque that is required to turn the load. The load torque is proportional to the weight of the load and the friction of the load.
Slip: The slip is the difference between the rotor speed and the synchronous speed. The slip is directly proportional to the load torque and inversely proportional to the synchronous speed.
Here is a formula that can be used to calculate the slip of an induction motor:
