Abstract
1500943 Commutators for dynamo-electric machines CANADIAN GENERAL ELECTRIC CO Ltd 11 March 1975 [13 March 1974 3 Sept 1974] 10014/75 Heading H2A A discoidal armature comprises a circular array of overlapping coils bonded together to form a rigid discoidal structure including a disc portion 26 integral with and disposed radially between radially inner and outer ring portions 25, 27, the armature including a commutator 23 comprising at least one ring of segments mounted on the outer ring portion. In the dynamo-electric machine shown, the disc portion 26 is disposed between stator permanent magnets 35, 36 and the commutator has a cylindrical working surface between two prestressed bands 29, 30 which hold the segments in position. In a modification, Fig. 2, the commutator segments 42 are U-shaped and are disposed astride the outer ring portion 41 of the armature so as to provide two radial working surfaces 47, 48. In a modification of the Fig. 2 construction, Fig. 3 (not shown), the bases of the U-shaped segments are split so as to form two separate commutators. In a further modification, Fig. 10 (not shown), four separate face commutators are mounted on the radially outer ring portion of the armature winding. In all embodiments an epoxy or polyester resin may be used to bond the coils of the winding together and to secure the commutator segments to the outer ring portion of the winding. The resin may also serve to provide insulation between the different commutators where two or more commutators are employed.
