An induction motor operates on the fundamental principle of electromagnetic induction. When a three-phase alternating current is supplied to the stator windings, it generates a rotating magnetic field. This rotating field interacts with the conductors within the rotor, inducing a current in them. Due to this induced current, a magnetic field is created within the rotor. The interaction between the stator's magnetic field and the rotor's field results in a torque that causes the motor shaft to rotate.
The speed of rotation depends on the frequency of the supply current and the number of poles in the stator winding. Induction motors are known for their robust construction, reliability, and relatively low maintenance requirements. They find widespread applications in industrial machinery, pumps, fans, compressors, and various other rotating equipment.
