Abstract

1,262,486. Brushes for dynamo-electric machines. C.A.V. Ltd. 15 May, 1969 [29 May, 1968], No. 25690/68. Heading H2A. In a dynamo-electric machine including at least one pair of carbon brushes passing current to windings on a rotor assembly, at least one of the brushes has a wire mounted thereon, so that when the brush reaches the end of its useful life the wire contacts the commutator or a slip ring of the machine and so completes a warning circuit. The wire 22 may be mounted either in an insulating plug 21 in the brush 18, as shown, or in a groove in a side face of the brush, the wire being insulated from the brush. The warning circuit includes a detector 24, e.g. a lamp.
