Rotating Magnetic Fields in Three-phase AC Induction Motors



The following animation shows how the “rotating” magnetic field of a three-phase AC induction motor is produced by the interaction of three stator winding sets energized with different phases (A, B, and C) of a three-phase AC power source. A red arrow shows the direction of the resultant magnetic field created by the interaction of the three winding sets.
