摘要： An electric motor (1) includes a rotor (20), a commutator (30), a first conducting brush (41), a second conducting brush (42), a first auxiliary brush (51), and a second auxiliary brush (52). The rotor (20) has a shaft (21). The commutator (30) is attached to the shaft (21). The first conducting brush (41) and the second conducting brush (42) are in contact with the commutator (30). The first auxiliary brush (51) and the second auxiliary brush (52) are in contact with the commutator (30). The commutator (30) includes commutator segments (31) provided in a circumferential direction of the shaft (21). The first auxiliary brush (51) is disposed so as to come into contact with a commutator segment (31) having the same electric potential as a commutator segment (31) just separated from the first conducting brush (41), among the commutator segments (31). The second auxiliary brush (52) is disposed so as to come into contact with a commutator segment (31) having the same electric potential as a commutator segment (31) just separated from the second conducting brush (42), among the commutator segments (31).

摘要： A commutator motor is configured such that an armature includes an armature core having teeth and slots, an armature coil, and a commutator having segments. The armature coil includes coil units in which windings are wound on the teeth, and jumper wire units for interconnecting between the coil units. Segment group includes first and second segments to which the coil units are connected, and a third segment to which only the jumper wire unit is connected. The first and second segments are disposed adjacent to each other, and the third segment is disposed next to the adjacent arrangement. The configuration includes the jumper wire unit that is wired from the third segment such that each of one part of the wire unit running to one side and the other part of the wire unit running to the other side is wired to pass through the same slot to interconnect between the coil units.

摘要： An electric motor (1) includes a commutator (30) including commutator segments (31), a first conducting brush (41) and a second conducting brush (42) in contact with the commutator (30), and a first auxiliary brush (51) and a second auxiliary brush (52) in contact with the commutator (30). The first auxiliary brush (51) and the second auxiliary brush (52) are connected to each other via a diode (80). When the first conducting brush (41) separates from one of the commutator segments (31), the first auxiliary brush (51) comes into contact with two commutator segments (31) including the one of the commutator segments (31) and a commutator segment (31) behind the one of the commutator segments (31) in a direction of rotation. When the second conducting brush (42) separates from another commutator segment (31) (commutator segment (31) different from the one of commutator segments (31)), the second auxiliary brush (52) comes into contact with two commutator segments (31) including another commutator segment (31) and a commutator segment (31) behind another commutator segment (31) in the direction of rotation.

摘要： A motor according to the present invention includes bearing (11) which includes: inner ring (11a) having upper end surface (11d), outer ring (11b), and balls (11c) between inner ring (11a) and outer ring (11b). Pressurizing spring (12) is inserted onto rotary shaft (3), is located between core (4) and bearing (11), and provides bias forces in the axial direction of rotary shaft (3). Outer ring (11b) is pressed to fit into bearing holding part (9a). Inner ring (11a) is fitted onto rotary shaft (3) with gap (15) therebetween. Upper end surface (11d) of inner ring (11a) is in contact with pressurizing spring (12). Pressurizing spring (12) applies the bias forces of different strengths onto a surface in which upper end surface (11d) contacts with pressurizing spring (12), along a circumferential direction with the axial direction as a center.
