ABSTRACT:
A polyphase brushless DC motor has an integral automatic feedback arrangement affording excellent accuracy and a high degree of magnetic balance. The stator pole elements of the motor are identical and equidistantly spaced, and each is wound with two coils. One coil on each pole element comprises sensor circuitry; the other comprises power circuitry. As a result, all pole elements of the stator are utilized both to produce rotor drive torque and also to generate electrical signals that provide highly accurate rotor-position information.
