摘要： An arc length in contact with a commutator of two brushes in a rotational direction of a motor is defined as not more than 5% of an outer rim length or circumference of the commutator, i.e., not more than πA/2O, where A is an outside diameter of the commutator. A number of shorted segments of the commutator, which short is caused by the brush, can be minimized so that reduction in output of the motor can be prevented. As a result, the motor employed in a car product or an electric tool can be downsized and made lighter.
摘要翻译：与电动机的旋转方向上的两个电刷的换向器接触的电弧长度被定义为不大于换向器的外缘长度或周长的5％，即不大于piA / 2O，其中A是换向器的外径。换向器的多个短路段，其由电刷引起的短路可以最小化，从而可以防止电动机的输出的减小。因此，汽车产品或电动工具中使用的电动机可以被小型化并且变得更轻。

摘要： The present invention provides for its object a compact electric motor effective to provide a high reliability against the leakage of grease from a bearing on one side adjacent the output shaft or the ingress of oil from a counterpart machine. The compact electric motor 1 has a wall 14 having a predetermined gap around an output shaft 3 between a commutator 7 and a bearing 6, wherefore in the event of leakage of grease from the bearing 6 on an output side or ingress of oil from the counterpart machine, it is possible to prevent deposition on the commutator 3 and the brush 5 and, hence, to avoid an abnormal wear of the brush 5 and reduction in performance of the compact electric motor 1.
摘要翻译：本发明的目的是提供一种紧凑型电动机，其有效地提供高的可靠性，以防止润滑脂从邻近输出轴的一侧的轴承或来自对应机器的油的进入泄漏。紧凑型电动机1具有壁 14在换向器7和轴承6之间具有围绕输出轴3的预定间隙，因此在输出侧的轴承6或来自对应机器的油的入口处的润滑脂泄漏的情况下，可以防止沉积在换向器3和电刷5上，从而避免了电刷5的异常磨损和小型电动机1的性能下降。

摘要： A DC motor has a projection which projects from the bottom surface of the brush-holder plate. The projection extends to outside in the axial direction of the motor. A terminal conductor is inserted into a perforated hole formed in the projection. One end of the terminal conductor is exposed to the outside of the motor from the tip of the projection, while another end of the terminal conductor is connected electrically to the brush. The projection functions as the built in type electrical connector to the motor, which when coupled to a power supply, powers the DC motor.
摘要翻译：直流电动机具有从电刷架板的底面突出的突起。突起在电机的轴向延伸到外侧。端子导体插入形成在突起中的穿孔中。端子导体的一端从突起的尖端暴露于电动机的外部，而端子导体的另一端电连接到电刷。投影功能用作电机的内置型电连接器，当连接到电源时，为直流电机供电。
