WebMay 7, 2024 · While we include numerous illustrations of two-phase motors for simplicity, we must emphasize that nearly all poly-phase motors are three-phase. By induction motor, we mean that the stator windings induce a current flow in the rotor conductors, like a transformer, unlike a brushed DC commutator motor. AC Induction Motor Construction WebPolyphase electrical power was found to be very useful in AC motors, such as that of the induction motor. In this instance a rotating magnetic field is generated. When a three-or-more-phase electrical supply completes one full cycle, the magnetic field of a two-poles-per-phase motor will have rotated through 360° in physical space.
