摘要： A drive mechanism including a brushed motor comprises a brushed motor including a commutator having a plurality of commutator segments and a brush contactable to the plurality of commutator segments, a movable member driven by the brushed motor, and a stopper member configured to stop rotation of the brushed motor by contacting the movable member. In a state in which the movable member contacts the stopper member to thereby stop the rotation of the brushed motor, the brush contacts only one of two adjacent commutator segments of the plurality of commutator segments.

摘要： Each brush holder is formed by bending a holder material made of a metal plate, so that the brush holder is shaped into a generally rectangular tubular body, which includes opposed first and second lateral walls, a top wall and a base wall. A base plate includes holder limiting grooves. Each brush holder is received in a corresponding one of the limiting grooves. The limiting groove limits an increase in a space between the first lateral wall and the second lateral wall of the corresponding brush holder. Furthermore, each brush is received in a corresponding one of the brush holders in a slidable manner in a sliding direction toward and away from a commutator of a motor.

摘要： A brush assembly is provided that facilitates a longer usable brush life and permits easy brush assembly replacement. The brush assembly includes an arc-shaped brush and a pivot arm, with the mounting end of the arc-shaped brush bound or otherwise mounted with respect to one end of the pivot arm. The end of the pivot arm that is not bound to the arc-shaped brush typically includes a female cylindrical slot for mating with a male shaft that is prefabricated in the motor housing, parallel to the rotor's axis. When the disclosed brush assembly is installed into an electric motor, the pivot arm slot is slidably positioned onto the shaft in the motor housing, enabling the brush assembly to pivot about the shaft on a plane that is perpendicular to the rotor's axis of rotation. A biasing spring force impels the brush assembly to pivot inward toward the rotor in the longitudinal direction of the brush, and maintains the operating end of the arc-shaped brush in contact with the rotating faces of the commutator. A single biasing spring is adapted to act upon both the brush and an interrupter device that is activated when the brush life is exhausted.
摘要翻译：提供了一种刷组件，其有助于更长可用的刷子寿命并允许更换刷组件。刷组件包括弧形刷和枢转臂，弧形刷的安装端相对于枢转臂的一端固定或以其它方式安装。枢转臂的未结合到弧形刷的端部通常包括用于与在马达壳体中预制的阳轴配合的阴圆柱形槽，平行于转子的轴线。当公开的电刷组件安装到电动机中时，枢转臂槽可滑动地定位在电动机壳体中的轴上，使得电刷组件能够在垂直于转子的旋转轴线的平面上绕轴枢转。偏置弹簧力推动刷子组件沿着刷子的纵向方向向内转向转子，并且保持弧形刷的操作端与换向器的旋转面接触。单个偏置弹簧适于作用于刷子和当电刷寿命耗尽时被激活的断续器装置。
