  • Multi-path liquid cooling arrangement for electric machines
    Patent number: 8643233
    Abstract: A multi-path liquid cooling arrangement for electric machines includes a heat storing element provided with channels having a generally C-shaped cross-section and cooling tubes so configured and sized as to be insertable in the channels is described herein. The cooling tubes, once inserted in the channels, are deformed to conform thereto, whereby heat stored in the heat storing element is extracted by circulating cooling fluid inside the cooling tubes.

  • Permanent magnet rotor assembly
    Patent number: 7898136
    Abstract: An illustrative embodiment of the present invention is concerned with a permanent magnet rotor for an electric machine provided with an internal stator and a coaxial external rotor. To overcome the drawbacks associated with the use of an adhesive to mount the permanent magnets to the rotor body, permanent magnet spacing and retaining elements are mounted to the inner surface of the rotor, between adjacent magnets.
