  • Rotating rectifiers with nested diodes
    Patent number: 9912213
    Abstract: A rectifier includes a diode with an anode face and an opposed cathode face that are both angled in relation to a rotation axis of the diode. A first diode plate overlays the diode anode face. A second diode plate overlays the opposed diode cathode face. The first and second diode plates are nested with one another such that portions of the diode plates axially overlap one another along a length of the diode rotation axis.
    Type: Grant

  • Hybrid stepper motor having magnetic enhancement and heat dissipating housing
    Publication number: 20080030108
    Abstract: A hybrid stepper motor includes a stator having a number of poles. Teeth are formed on the stator poles and separated from each other by slots. A magnet is inserted in the slots to a predetermined depth from a top surface of the stator teeth. The motor further includes a rotor that is provided coaxial with the stator. Teeth are also formed on the rotor opposite the stator teeth. The rotor teeth enable the rotor to be rotated relative to the stator in cooperation with the stator teeth.

  • Method for winding a stator of multi-phase motors
    Patent number: 7152301
    Abstract: A method for winding a stator of a multi-phase motor includes successively winding each of a plurality of teeth on the stator with a continuous winding wire to connect each of the phases in the motor together. The wound wire is disconnected between any two phases where respective ends of the two phases connected by the winding wire are not neutral ends. A jumper wire is connected between a neutral end of any one of the phases to a neutral end of at least one other phase if the neutral end of any one of the phases is not connected to the neutral end of at least one other phase by the winding wire.
