Induction motors are widely used in dairy plants for operating equipment such as pumps, compressors, agitators, cream separators, and refrigeration systems. These motors work on the principle of electromagnetic induction, where electric current in the stator winding produces a magnetic field that induces current in the rotor, resulting in mechanical rotation. A three-phase induction motor operates on the principle of a rotating magnetic field. The stator of the motor contains three windings placed 120 degrees apart from each other. When a three-phase alternating current is supplied to these windings, three alternating magnetic fluxes are produced. These fluxes combine to form a rotating magnetic field that revolves around the stator at synchronous speed. The rotor, which is usually of squirrel cage type or wound type, is placed inside this rotating magnetic field. According to Faraday’s law of electromagnetic induction, the rotating magnetic field cuts the rotor conductors and induces an electromotive force in them. Since the rotor circuit is closed, current flows through the rotor conductors. This current interacts with the rotating magnetic field of the stator and produces electromagnetic torque according to Lorentz force principles. As a result, the rotor starts rotating in the same direction as the rotating magnetic field. The rotor cannot reach the synchronous speed of the stator field because relative motion is necessary for induction to occur. The difference between synchronous speed and rotor speed is
