Slip in an induction motor is not a flaw but an essential working principle, defining the difference between the synchronous speed of the rotating magnetic field and the actual rotor speed. Understanding the phenomenon of slip is fundamental to grasping how these motors operate and why they are so reliable.
Slip Calculation Formula Induction Motor
The motor automatically draws more power from the electrical supply to match the mechanical demand, maintaining a stable operating speed under varying conditions. For example, a standard four-pole motor operating on a 60 Hz supply will have a synchronous speed of 1,800 RPM.
This decrease in rotor speed increases the slip, which in turn induces a higher current in the rotor windings to generate the additional torque required to drive the load. Therefore, slip is the price paid for the electromagnetic induction that produces the motor's driving force.

This cessation of relative movement would stop the induction of current in the rotor, eliminating the torque and causing the motor to stop. If the rotor somehow matched the synchronous speed, the relative motion would cease, and the magnetic field would no longer cut across the rotor bars.
