Abstract

The metal case (2) for the multi-layer brushes of an A.C universal motor is made of a punched plate of metal which has been coated by an insulating layer of PTFE (22) and formed to shape. The brush consists of two layers (31,32) with an insulating layer (33) between them. The brush pressure is exerted by a leaf spring (5).
