Abstract

1487877 D.C. electric machines; commutating arrangements KOLLMORGEN CORP 27 Aug 1975 [30 Aug 1974 9 May 1975] 35320/75 Heading H2A A commutating arrangement for the stator winding 17 of a D.C. machine comprises stationary commutator segments 19 engaged by rotormounted rollers 35 which are electrically connected to respective slip rings 23, 24 engaged by stationary brushes 25, 26 connected to a D.C. supply. The rollers are independently and resiliently mounted, Fig. 2, not shown, and may have passages (35, 35b) formed therein for directing air at the commutator bars to remove dust and other particles. In a high speed embodiment, Fig. 6 (not shown) the rollers are of much larger diameter than those shown and engage the radially outer periphery of a stationary commutator. In a further embodiment, Fig. 5 (not shown), the machine rotor and stator are mounted in a hermetically sealed housing (61), the rotor being magnetically coupled to the roller assembly which, together with the slip rings and commutator bars, is mounted in a separate housing (65) attached to the main housing.
