The present invention relates to an electrical machine and more particularly to an arrangement of cooling passages within the stators of such machines. Cooling fluid is caused to pass through a number of channels provided in a space between winding discs to provide improved cooling of the winding discs.

Stator cooling

The present invention relates to a turbocharger and motor assembly, in which the motor ( ) is coupled to one side of the turbocharger ( ) to provide additional acceleration of the turbocharger rotor ( ) at low engine speeds and to reduce the power provided from the exhaust gases at higher speeds.

Electric turbocharging system

A rotary electrical machine which has a plurality of disc-shaped stator stages and a plurality of disc-shaped rotor stages, each of the rotor stages being respectively alternately interleaved with the stator stages. A space is provided between each stator stage and its adjacent rotor stage. Each of the stator stages is provided with at least two stator windings, defining a passage therebetween adjacent windings. A coiled pipe is disposed in or formed integrally with each of the passages in substantially the same plane as the stator stage, such that the outlet of one pipe is coupled with the inlet of the pipe disposed in the adjacent passage. In use, fluid, for example air, helium, water or oil is caused to flow around the coiled pipes in the passages between the stator windings. At the same time, cooling gas, for example, air or helium, is caused to pass through the stator-rotor spaces so as to cool the magnets, etc. and the retention hoops, etc. of the rotor stage as well as the outer surfaces of the stator stage. Alternatively, the stator-rotor spaces may be held under a vacuum.

Rotary electrical machines

A retention ring (,) is applied to a disc rotor assembly (,) which comprises a plurality of substantially equiangularly spaced magnets (,). The ring is expanded by driving it over a tapered mandrel (,) onto a rim (,) of the rotor assembly.
