induction motor
Quick Summary
An induction motor is an alternating-current motor that generates torque through the interaction of a varying magnetic field in the stator and the induced current in the rotor's coils. The stator contains windings that, when connected to a three-phase electric supply, create a rotating magnetic field. This rotating field induces voltage and current in the rotor conductors. The interaction between the rotor currents and the magnetic field produces torque, causing the rotor to spin. The rotor's speed is slightly less than the rotating magnetic field's speed, a difference known as slip. Induction motors are robust and economical, with common applications including conveyors, pumps, and rapid-transit vehicles.123
