High efficiency DC motor with generator and flywheel characteristics

A high efficiency, high torque multiphase direct current machine which operates simultaneously in a motor-mode, in a generator-mode, and in a flywheel-mode comprising:

• an inner stator disk, with one or more air core coils mounted equidistant apart in a periphery of said stator disk and positioned so that said air core coils are energized in equilaterally balanced groups;
• a pair of outer rotor disks disposed parallel to and aligned with one another;
• said stator disk and said rotor disks being made of strong lightweight plastic structural materials;
• a fixed central shaft coupled to said rotor disks and passing through said stator disk, where said shaft is sandwiched in a fixed position between said rotor disks;
• a plurality of permanent magnets arranged in two paired sets, said magnets of each one set are mounted equidistant apart in a periphery of each one rotor disk, with each pair in polar alignment and poles of each pair reversed in every other pair;
• a generated current sensor and a generated voltage sensor for use in generator-mode;
• a current consumption sensor and a voltage consumption sensor for use in motor-mode;
• a rotor position sensor;
• a switching means for controlling power to said coils;
• a feedback controlled rectifying means to recover and control generated energy;
• a rechargeable power pack including electronically controlled rectifying devices, driver electronics, a capacitor bank, and rechargeable batteries, where said machine concomitantly in generator-mode utilizes inductive kickback, back-emf, and regenerative braking to recharge said power pack;
• and,
• a microprocessor controlling electronic commutation and operation of said machine by utilizing data derived from said sensors.
