Abstract:
A dual concentric AC motor allows for two independently operating AC motors that produce the same torque at the same current input as two conventional, separate electric motors while occupying a smaller physical volume. The dual concentric AC motor utilizes a single, hollow cylindrical stator core comprising inner and outer stators and an inner rotor and an outer rotor that operate independently of one another. The inner stator, with windings that face toward the center of the motor, couples to the inner rotor, which rotates inside the single stator core, while the outer stator, with windings that face away from the center of the motor, couples to the outer rotor, which rotates around the single stator core. A back iron, centrally located in the single stator core, physically and magnetically separates the inner and outer stators. The two rotors are coupled to separate, independent output shafts.
