AC Three Phase Electric Motors

The AC induction motor is a rotating electric machine designed to operate from a three-phase source of alternating voltage. The stator is a classic three-phase stator with the winding displaced by 120°.

  • Medium construction complexity, multiple fields on stator, cage on rotor
  • High reliability (no brush wear), even at very high achievable speeds
  • Medium efficiency at low speed, high efficiency at high speed
  • Driven by multi-phase Inverter controllers
  • Motor EMI good but… terrible EMI from inverter
  • Sensorless speed control possible
  • Low cost per horsepower, though higher than for 1-phase AC induction motor
