  • Electric machine with stator windings having over-under end loops
    Patent number: 11018541
    Abstract: A multi-phase electric machine having plurality of windings are mounted on the stator core and define a plurality of phases with each phase having at least two parallel windings. A standard pitch is defined between each pole of each phase, the pitch being a common circumferential spacing between corresponding slots of each pole. Each of the windings has a position change end loop at the same location, wherein the position change end loops define a non-standard pitch to thereby change the relative positions of the parallel windings in the slots. At each set of such position change end loops, the windings defining a greater pitch extend over the windings defining a lesser pitch.

  • Fractal switching systems and related electromechanical devices
    Patent number: 10971294
    Abstract: This invention entails the use of fractal shapes as cores for electromagnets, and a concurrent shape of a fractal for the windings which surround it. The novelty of this invention lies not only with the shaping, but the advantage of such shaping, which includes producing a smaller form factor electromagnet for the same desired magnetic field strength, when compared to a conventional electromagnet. It will be appreciated that a range of devices including electromagnets, based on such fractal shaping, are additionally novel and include but are not limited to solenoid switches, relays, and other devices in which the fractal electromagnets are used to make a change in state of some device.
