ABSTRACT:
An electronic motor includes a shaft mounted for rotation about a rotational axis. A plurality of radial lever arms are mounted with respect to the shaft. Each lever arm has an inner end connected to the shaft by a one-way clutch. The clutches allow the shaft to rotate in only a first circumferential direction with respect to the lever arms. An electrically conductive element is attached to an outer end of each lever arm. A drive coil is positioned adjacent to each electrically conductive element. A drive circuit periodically and sequentially energizes each drive coil with current pulses. Each drive coil is oriented to produce a first pulsed magnetic field in a direction generally tangential to the circumferential direction when energized. The first magnetic field induces circulating currents within the electrically conductive element. The circulating currents in turn produce a second magnetic field about the electrically conductive element. The first and second magnetic fields interact and force the radial lever arm to rotate in the first circumferential direction thereby engaging and rotating the shaft.
