An electric motor, in particular a motor and gear box unit for activating functional equipment in a vehicle, includes a rotor shaft () carrying a commutator () co-operating with conductive brushes () disposed in brush supports () fixed to a printed circuit card (); the motor is provided with means for enabling brush supports to be fixed to the printed circuit card solely by surface mounting. These means may comprise, for each brush (), a metal casing () containing the brush and having one wall () with at least one transverse tab () adapted to pass through the printed circuit card in order to position and hold the casing on the card and in order to provide an electrical connection. The invention enables brush-support devices to be fixed to the printed circuit card solely by surface mounting, thus making it pointless to perform an additional flow soldering operation as is required in the prior art.

Brush-holder for a carbon brush

A commutator housing for an electric motor includes a support to receive a commutator having at least two integrated stops and at least two brushes each fixed on a spring component. The spring components force the brushes into a contact position against the commutator. The stops hold the spring components in a mounting position in which the brushes are distanced from the contact position.

Brush holder for a carbon brush

A connector for an electric motor including a magnetic ring which is the seat of a magnetic field tied to operating parameters of the motor. A magnetic flux conduction member forms a flux concentrator interposed, when a connector is fixed on the motor, between the magnetic ring and a Hall-effect sensor to measure the magnetic flux conducted by the magnetic flux conduction member. The electric motor can be used with geared motors for window-lifting systems, seat actuation systems or sunroof systems in the automobile field.

Connector with flux concentrator for electric motor

A device for a window lifter of a vehicle door includes a cable winding drum disposed inside a housing of a casing and a seal attached to the casing. The seal includes a stop portion that prevents translational movement of the drum along its rotational axis while still allowing the drum to rotate freely about the axis. The inventive device allows the drum to be held in the housing before the casing is mounted on a dividing panel without requiring auxiliary parts to hold the drum in place and without compromising the seal when the casing is fastened to or removed from the dividing panel.
