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.

Multi-path liquid cooling arrangement for electric machines

A stator assembly is provided with detachable teeth that are made of magnetic powder material. The teeth are so configured and sized as to be interconnected to a core body of the stator with pre-formed coils that are positioned between adjacent teeth.

Stator assembly for electric machines

A cooling assembly to be positioned inside an internal stator of an electric machine is described herein. The cooling assembly includes a plurality of cooling segments that may be so mounted to a support structure as to be biased towards an inner surface of the stator.

Cooling assembly for large diameter electric machines

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.
