Patent number: 7629722Abstract: An electric motor assembly device includes a carrier member with a central passage that receives a rotor shaft with a commutator. Brushes secured onto flexible, brush holders urge the brushes towards the central passage into a contact position with the commutator. The carrier member has mechanical elements for restraining the brush holders in an assembly position for assembly where the brushes clear the central passage and are protected against impact by the carrier member. This arrangement allows the rotor shaft to be introduced into the central passage of the carrier member without a risk of damaging the brushes. The brush holders are easily released automatically from the mechanical elements on the electric motor assembly device to bring the brushes into the contact position.Type: GrantFiled: February 22, 2007Date of Patent: December 8, 2009Assignee: ArvinMeritor Light Vehicle Systems - FranceInventors: Philippe Raoul, Gerard Fournier, Benoit Bazin, Stephane Omelezuk

Patent number: 7608971Abstract: An electric motor, in particular a motor and gear box unit for activating functional equipment in a vehicle, includes a rotor shaft (1) carrying a commutator (2) co-operating with conductive brushes (3) disposed in brush supports (4) fixed to a printed circuit card (5); 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 (3), a metal casing (6) containing the brush and having one wall (6) with at least one transverse tab (11) 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.Type: GrantFiled: November 7, 2006Date of Patent: October 27, 2009Assignee: Meritor Light Vehicle Systems - FranceInventors: Hervé Laurandel, Philippe Raoul

Patent number: 7129610Abstract: A commutator includes a support ring and a plurality of conducting segments arranged over a circumference of the support ring. Some of the conducting segments have an electrically insulating portion. The commutator is employed with a device that measures rotation of an electric motor rotor shaft. The commutator is fitted onto the electric motor rotor shaft. A commutator housing includes at least three brushes and comes into contact with the conducting segments of the commutator. At least one of the brushes contacts the electrically insulating portions of the commutator segments to provide an electrical measurement that enables the speed, the direction of rotation and the angular position of the electric motor rotor shaft to be determined.Type: GrantFiled: April 13, 2005Date of Patent: October 31, 2006Assignee: ArvinMeritor Light Vehicle Systems-FranceInventors: Dan Mirescu, Philippe Raoul

Publication number: 20050240837Abstract: A method of operating a control unit (CU) begins by performing a power on reset. If the CU receives a start-up message within a predefined time period after the reset, then the CU enters a diagnostic mode in which a diagnostic communication can be established with a diagnostic unit. If no start-up message is received within the predefined time period, the CU enters a normal mode of operation. The CU includes a memory designated to store data unique for a respective vehicle type, a first communication module allowing communication via a bus system under a first protocol for normal operation of the CU, and a second communication module allowing communication via the bus system under a second protocol for accessing the memory.Type: ApplicationFiled: April 27, 2005Publication date: October 27, 2005Inventors: Laurent Dubois, Philippe Raoul, Gerhard Mersch
