Abstract: An operating and control device, for example for an electric motor, includes a support having by a first metal part in which is formed a network of conduits conveying a cooling fluid for electrical elements, and a second part, made of insulating material, housing electrical links for connections with those electrical elements, a source of energy and other electrical components. The invention applies in particular to automobiles with an electric motor.

Abstract: A brush holder device for a commutating electric machine including a ring (7) integral with the stator, brush holders (6) fastened in a mounting position on the ring and connected electrically in pairs by conductors (101, 102) the ring being located perpendicularly to an axis of rotation (X--X') of a rotor (1) of the motor (M), a part whereof projects through a center opening of the ring (7). Each brush holder includes a recess located facing the periphery of the projecting part of the rotor (1) a commutator brush (5) is mounted in the recess so as to establish an electrical contact between the rotor and the stator. The brush holders (6 ) and the conductors (101, 102) form an integral part of the ring (7) made of a thermally stable insulating material. The brush holders (6, 6') and the conductors (101, 102) are fastened in their assembly position by being molded into an insulating and thermally stable material forming the ring.
