20150048695 | Method and apparatus for radial electromagnetic power arrays - Multiple arrays of linear motors and generators are combined in a radial configuration to provide high mechanical efficiency to deliver power in a single plane of motion to a common crankshaft. Magnet core assemblies for the motors and generators use powerful rare earth magnets positioned within an outer flux containment shell comprising a highly-magnetically-permeable ferrous-alloy to provide high power density. The motor magnet stack is attached directly to a link rod that connects to the crankshaft. Pulsed power is provided to electromagnetic coils coils by microcomputer control, and coil energy is recovered at the ends of the linear stroke. A controller energizes the coils in certain combinations of coil location and polarity in order to produce bi-directional mechanical motion. Energy that is released when coils are switched off is harvested as voltage pulses returned to standby batteries or capacitors, or the electrochemical cells. | 02-19-2015 |
