A cooling arrangement to cool the rollers of a toroidal CVT is described herein. The cooling arrangement includes nozzles so configured and sized as to project cooling fluid onto the edge and onto the opposite top and bottom surfaces of the roller.

Roller cooling arrangement for toroidal CVT

A method where the spin factor is looked up in a table; the slip factor is measured and the clamping pressure is adjusted to achieve a slip/spin ratio provided in a desired range is described herein. According to another aspect, an active mechanical clamping mechanism using a longitudinally movable contact point is also described.

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.

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.
