Industrial Applications – AC Induction Motor

Most motors are AC induction motors. In fact, more than 80% of all motors are AC induction motors. An AC induction motor can be single phase, poly-phase, brushed, or brushless. Unlike DC motors, they can reliably operate heavy workloads over one horsepower (750 watts) and three-phases are required for the largest motors. In an induction motor, the stator windings induce a current flow in the rotor, like a transformer (unlike a brushed DC commutator motor.)
