  • Publication number: 20040007936
    Abstract: A magnetic circuit component having a plurality of claws arranged in a plurality of rows, with the base of each claw connected to a common yoke. A plurality of non-interlaced coils constituting a multi-phase winding are included, with the coils being wound around the bases of corresponding claws, and being distributed uniformly in the direction of motion.

  • Patent number: 6630764
    Abstract: The system includes a permanent magnet three-phase motor and an electronic current controlled inverter by pulse width modulation. The motor has twenty-two poles and twenty-four slots, three phases and a cylindrical outer rotor. This structure minimizes torque ripple and maximizes energy efficiently. All coil windings are wound around the stator teeth. Several winding configurations are proposed and a special one with only one coil per slot. The motor phases are supplied by alternating rectangular current waveforms. A specific inverter control system is described to maximize efficiency and reduce current ripple and electromagnetic interference under motorizing or generating operations. The current control is realized by using the mosfets voltage for the current measurement.
