  • Patent number: 9438094
    Abstract: The arrangement of an electric machine, a connecting system and a converter, includes the connecting system connected between the electric machine and the converter. The connecting system has an enclosure that houses non-shielded conductors each non-shielded conductor is connected between a phase of the electric machine and the inner side of the converter. The non-shielded conductors of the connecting system that are connected to an operating phase of the electric machine are adjacent to conductors of the connecting system that are not connected to operating phases of the electric machine.
    Type: Grant

  • Patent number: 9231447
    Abstract: Apparatus for producing electrical power from mechanical power, includes an electric generator with a rotor and with a stator. The electric generator is configured for conversion of mechanical power into a polyphase alternating current. The polyphase alternating current has more than three phases. The stator has a stator core with a stator bore. The stator core provides a plurality of stator slots arranged at a distance from one another. A plurality of coil portions are inserted in the stator slots, and the coil portions are connected to form coils. The coils include a plurality of Z-shaped portions and are laid out in a wave pattern.

  • Publication number: 20150114676
    Abstract: A conductor bar including a plurality of Roebel-transposed conductor elements is disclosed. At least one of the conductor elements possesses a plurality of conductive strands stacked relative to each other. The strands used to form the at least one conductor element follow a common path within the conductor bar. An insulator electrically insulates the conductor elements from each other. Also provided are a method of manufacturing a conductor bar and an electric machine including a plurality of conductor bars.
