Abstract: A component that includes a longitudinal axle, having a multiple keybars that extend outward from a surface of the axle, such that each of the keybars are disposed axially along and circumferentially around the axle. Also the axis of the keybars is parallel to the axle, such that a profile of all midpoints of the keybars is helicoidal around the axle, also the helicoidal profile is such that they make up one or more helicoidal paths. The profile may be herringbone skewed. The component may be part of a rotor assembly that is part of an electric machine such as an interior permanent magnet (IPM) or Synchronous Reluctance motor.

Abstract: An assembly includes multiple adjoined rotor sections each having multiple poles and multiple void rows therethrough that are radially distributed in each of the poles. The rotor sections are skewed in a circumferential direction. The assembly also has multiple conductive rings that substantially surround one of the void rows. A method of assembly and electric machines and vehicles using the assembly are also disclosed. Aspects reduce torque ripple in electric machines and allow for encoderless/sensorless operation in an electric machine using the rotor assembly. The present invention has been described in terms of specific embodiment(s), and it is recognized that equivalents, alternatives, and modifications, aside from those expressly stated, are possible and within the scope of the appending claims.

Abstract: A power generation system includes a conducting tube and a generating unit configured to move linearly over a conductive surface of the conducting tube. Further, the generating unit includes a magnetic rotor configured to create a first magnetic field proximate the conductive surface and a stator disposed concentric with and radially inside the magnetic rotor, and including electrical coils. The magnetic rotor rotates about the stator to induce a voltage in the electrical coils when the generating unit moves linearly over the conductive surface of the conducting tube.
