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： An electric motor has a rotatable armature having two pairs of poles, including a lamination stack which has a shape which is symmetrical about its axis and which forms twenty radial teeth and twenty slots and which has, associated therewith, a commutator with twenty segments, and a distributed closed winding, the conductors of which extend into the slots and are connected to the segments of the commutator in a predetermined manner. The winding of the armature has a lap-type winding or coil section connected to two adjacent segments of the commutator and, in series therewith, a plurality of wave-type winding sections or coils. All of these sections or coils encompass a same number of slots.

摘要： In an electric motor having high-speed and low-speed brushes, durability is improved and vibration/noise is reduced. The electric motor has a low-speed brush 21a, a high-speed brush 21b, and a common brush 21c. Formed in the electric motor are a first coil 7A1 which is wound between given slots 11, and a second coil 7A2 which is wound in a direction opposite to a direction of the first coil 7A1 between slots 11 existing at positions point-symmetric to the given slots 11 with respect to a center of a rotation shaft. An armature coil 7 is formed by the first and second coils 7A1 and 7A2. If the armature coil 7 is short-circuited by the high-speed brush 21b, the first coil 7A1 and the second coil 7A2 of the short-circuited armature coil 7 exist at positions symmetric to each other with respect to an axis line extending through the center of the high-speed brush 21b and the center of the rotation shaft.
