Embodiment Construction

[0046] The commutator bracket according to the invention comprises a support, flexible tongues and brushes attached to said flexible tongues.

[0047] The flexible tongue is designed to force the brushes into contact with the commutator. The catch is designed to hold the tongue in a retracted position from its contact position, ie to hold the tongue in a mounting position in which the brush leaves its contact position.

[0048] When the motor is assembled, the detent is actuated by a lever on a motor component (eg reduction gear housing). Therefore, the rectifier bracket does not require special components to actuate the detents. Thus, the design and manufacture of the rectifier bracket according to the invention is simplified.

[0049] The flexible tongue is firmly attached to the brush and forces the brush into its contact position. Therefore, the tongue has to be simply released from the retainer in order to place the brush in the contact position. This operation can be...

Abstract

A commutator bracket (10) for an electric motor comprising: a support (11), flexible tongues (16) and brushes (15) attached to the flexible tongues. The flexible tongue is designed to force the brush into a contact position against the commutator. The retainer (17) is designed to hold the flexible tongue (16) in a position retracted from the contact position, i.e. to hold the brush in a mounted position in which , the brush leaves its contact position.

Description

technical field [0001] The invention relates to a rectifier housing for an electric motor and a method of mounting a rectifier in such a housing. [0002] In particular, the invention applies to electric motors designed to drive motor vehicle equipment, such as window regulators, sunroof or seat operating motors. Background technique [0003] Document FR 2814868 describes such an electric motor including a rectifier. [0004] A commutator generally consists of a ring having a series of electrically conductive commutator segments around its edge, which is designed to fit securely on the rotor shaft. Electric motors generally include a stator frame and a rotor rotatably mounted within the stator. The motor also includes windings rigidly attached to the rotor shaft, each winding electrically conductively connected to two diametrically opposed laminations of the rectifier. [0005] The rectifier is usually mounted in a rectifier bracket which is rigidly attached to the stator...
