ABSTRACT:
Various devices for generating electrical or mechanical output, comprising a coil, a rotor assembly rotatable about an axis, the rotor comprising alternating magnet portion and flux conducting portions, each of the magnet portions having a first end with a first polarity and a second end with the opposite polarity and oriented along the periphery such that the first end of each magnet portion points toward the first end of the previous magnet portion and the second end of each magnet portion points toward the second end of the next magnet portion, a stator assembly having first and second sets of stator flux conductor extensions, each of the stator flux conductor extensions having a stator surface facing the rotor, wherein rotating the rotor assembly about the axis alternates the rotor assembly between a first and a second position, causing magnetic flux to flow. The stator and the rotor may be reversed in operation. Other variations are presented, including multiple geometries for both the permanent magnets and the flux conductive portions of the invention. A means of coupling the invention to an exterior device or apparatus is also discussed, as are ways to control the output of the device.
