摘要： A direct current motor is provided that includes an armature core, a commutator, coils, positive brushes, and negative brushes. The armature core includes a stator. The stator has magnets the number of which is represented by P (where P is an even number greater than or equal to six). The coils are wound about the teeth by duplex wave winding. Alternatively, the coils are wound about the teeth such that each pair of coils that are spaced apart by 180° are connected common ones of the segments. Each of the positive brushes and the negative brushes has an angular width WB, at which it slides on the segments. When the angular width of the arrangement pitch of the segments is represented by WP (WP=360°/the number of the segments), and the angular width of the clearance between each pair of circumferentially adjacent segments is represented by WU, the angular width WB is set to satisfy the expression: WB≦(4/P)×WP+WU.

摘要： A slide surface of each segment defines a plane orthogonal to an axial direction of a direct current motor. A power supply brush is pressed against and contacted with the slide surface. The power supply brush includes a main brush and a sub-brush. The sub-brush has electrical resistance that is higher than that of the main brush. At least the main brush supplies an armature with power. The sub-brush is arranged more inward in the radial direction of the commutator than the main brush.
摘要翻译：每个段的滑动表面限定与直流电动机的轴向正交的平面。电源刷被压紧并与滑动表面接触。电源电刷包括主电刷和副电刷。副刷具有高于主刷的电阻。至少主电刷为电枢供电。副刷子比主刷子在换向器的径向方向上更靠内侧布置。
