    Abstract: Provided are multiple switched reluctance motors and excitation control methods for same. Motors with various structures are provided having the same structural characteristics, a stator formed of an even number of salient pole pairs and a rotor formed of an even number of salient pole pairs. The salient poles of the stator salient pole pairs are arranged opposite the salient poles of the rotor salient pole pairs, with minimal air gaps left between said salient pole pairs, thus leaving the shortest magnetic return paths between the stator salient pole pairs and the rotor salient pole pairs arranged opposite one another, thus satisfying the minimum reluctance principle of the switched reluctance motor. In addition, due to the magnetic isolation between each stator salient pole pair, the performance of the magnetic pole of each stator salient pole pair is controlled by an excitation control power source and changed independently.

    Abstract: The invention implements a variation of the electrical transverse flux machine (motor or generator) that employs ferromagnetic excitation elements mostly located on the stator rather on the rotor. The excitation elements are employed in nearly-complete magnetic circuits that are periodically completed by the movement of the rotor. The varying flux that is thus generated is used to cause an EMF in windings, for the case of generators, or for the case of motors, appropriate EMF is used to cause varying flux that in turn causes rotation of the motor.

    Abstract: Electrical machines, for example transverse flux machines and/or commutated flux machines, may be “balanced” to achieve reduced overall cogging torque via utilization of one or more cogging torque reduction devices. Cogging torque reduction devices may be configured and/or otherwise customized in order to reduce and/or minimize cogging torque in an electrical machine, by generating a counteracting cogging torque waveform that at least partially counteracts and/or cancels the initial cogging torque waveform of the electrical machine.

    Abstract: An electrical machine includes a rotor with a rotational axis, a coil arranged circumferentially with respect to and fully encircling the rotational axis, and a stator assembly. The stator assembly includes first and second lamination stacks comprising associated pluralities of laminae, the stacks being arranged circumferentially with respect to the rotational axis on opposing sides of the coil for conducting magnetic flux. The stacks are configured with gaps generally radially through the laminae thereof, defining separate circumferential segments in each laminae, to prevent creating a continuous electrical circuit around the rotational axis in the segments. Each laminae has a connecting ring spaced radially from the segments, and beams connecting the segments to the ring as a unitary piece. Back return elements extend axially between the stacks to provide a flux path therebetween, and are positioned circumferentially between adjacent parts of the beams and radially between the segments and the ring.

    Abstract: A rotor is formed with a partition wall interposed between a first magnetic body and a second magnetic body. Projections of the partition wall block gaps between salient poles of the first magnetic body and salient poles of the second magnetic body which are arranged at shifted positions when seen in an axial direction of a rotating shaft to shield a flow of air flowing in the axial direction. Notches are formed in parts other than the gaps to decrease a volume thereof and to reduce inertia thereof.
