Abstract

1381109 Cooling electric machine rotors DEFENCE SECRETARY OF STATE FOR 22 Dec 1972 [22 Dec 1971] 59528/71 Heading H2A In an electrical machine, e.g. a motor, generator or rotary connector, having a rotor which includes a plurality of magnetic pole pieces 2 each carrying a winding 5, there are provided a fluid-retaining container 3 which encloses the rotor except that polepiece shoes 4 protrude through it, and coolant inlet and outlet passages for passing a flow of fluid coolant, e.g. oil through the container. As shown, the inlet passages comprise a coaxial bore 14 in the rotary shaft 15 and radial holes 13 connecting to an annular feed chamber 12 of the container 3 which container is provided with wedges 16 which restrict the coolant flow to narrow V-shaped channels 17 adjacent the windings and from which it flows via an annular receiving chamber 6 to the outlet passages which comprise six inclined outlet holes 7 opposite an annular aperture 10 in a stationary annular collecting chamber 8 attached to the main frame 9 and connected to an outlet pipe 11. Centrifugal force acting on the oil within the tube obviates the need for, or reduces the size of, any external pump required to circulate the oil.
