Abstract

See full text

What is disclosed are embodiments of magnetic torque transfer devices utilizing torque transfer by magnetic induction in which an induction cylinder fabricated from an electrical conductor is interposed into the gap between a pair of magnetically coupled primary and secondary rotors. Rotation of the induction cylinder relative to the coupled rotors evokes magnetic torque transfer in accordance with Lenz's Law. The primary rotor rotates within a toroid shaped stator. The stator may be configured for rolling biphasic coil control. The secondary rotor is attached to a propeller. The device may function as a turbine when fluid is directed to flow over the propeller. The device may function as a pump when AC power is supplied to the stator. Rolling biphasic motor control includes dividing motor coils into increments, then configuring groups of contiguous increments into virtual coils, which revolve in tandem with the primary rotor so to achieve continuous and optimal torque transfer with minimum torque ripple.
