摘要： A device may include a first end, a second end, and a coupler configured to extend through an aperture from a first side to a second side of a motor cover. The coupler includes a head portion, a conduit portion extending from the head portion towards the second end, and a first bore axially extending through the coupler. The device may include a brush holder extending through the first bore. The brush holder includes a cylindrical body, a socket at the first end, and a receptacle at the second end. The device may include a first lock nut including a first threaded bore axially extending through the nut. The device may be configured to enable a grounding brush to contact a motor shaft to provide a current discharge path to ground to reduce an erosion of the motor components including the motor shaft and rolling bearing elements.

摘要： The present disclosure relates to a motor with bidirectional terminals. According to the present disclosure, as the brush terminals are installed on both the left and right sides of the upper surface of the brush card assembly, it is possible to prevent the assembly defects of the motor due to the erroneous assembly of the brush terminals.

摘要： A framework is disclosed for holding magnets to provide a stator for an electric motor, in particular for a starter motor. The framework is adapted to removably receive, retain and space apart a plurality of magnets within the framework to form a tubular magnet array and provide said stator. The framework may provide a stator which is easier to assemble and more reliable than known stators. The framework provides a central aperture for receiving a rotor armature of said electric motor. The framework is arranged to be slidably inserted or removed from a housing of said electric motor. A frame portion, a stator, an electric motor, a vehicle drive assembly and a method of assembling an electric motor are also described. A brush housing comprising a plurality of passages for slidably retaining brushes and comprising a plurality of bias housings, and a brush assembly comprising the brush housing are also described.

摘要： An electric motor is provided including a stator and an armature rotatably received within the stator, the armature having an armature shaft on which a commutator is mounted. The motor also includes a brush assembly having a brush card mount disposed around the commutator, a brush holder mounted on a surface of the brush card mount, and a brush disposed within the brush holder in sliding contact with the commutator to supply electric current to the commutator. A torsion spring is secured to the brush card mount adjacent the brush holder, the spring having a leg arranged to engage the back surface of the brush. A spring stop post is disposed proximate an outer periphery of the brush card mount to limit an outward movement of the leg of the spring away from the back surface of the brush.
