摘要： A motor includes a housing, a back cover, a brush card, a brush, and a connector member. The back cover includes a first rear wall portion and a first peripheral wall portion. The first peripheral wall portion includes a through-hole and a cut-out. The through-hole vertically penetrates through the first peripheral wall portion at or near a lower end portion of the first peripheral wall portion. The cut-out is disposed farther on an upper side than the through-hole. The connector member is fitted into the cut-out. An outer surface of the connector member is provided with a flow path groove that extends in both peripheral and axial directions. The motor includes a flow path surface on an inner surface of the back cover. The flow path surface continues from a portion that opposes the flow path groove on a lower side of the flow path groove to the through-hole.

摘要： A motor includes a housing, a back cover, a brush card, and a brush. The brush card is disposed in a casing defined by the housing and the back cover. The brush is disposed on a front side of the brush card. The back cover includes a through-hole in the vicinity of a lower end portion of a first circumferential wall portion. The back cover and the brush card are in contact with each other in an annular or substantially annular shape, in a radially inner side of an inner circumferential surface of the first circumferential wall portion via a gap. The contact portion is disconnected, or the brush card is radially penetrated, at a position that radially overlaps with the through-hole.

摘要： A motor includes a rotor, a brush card assembly arranged to supply an electric current to the rotor, a housing, a permanent magnet, and a bearing. The rotor includes a core fixed to a shaft, a coil arranged to excite the core and a commutator connected to the coil. The coil is wound around the core in a concentrated winding method. The brush card assembly includes at least one pair of brushes having different polarities, the brushes disposed along a circumferential direction and connected to each other via the commutator and the coil, a X capacitor parallel-connected to the brushes, Y capacitors parallel-connected to the brushes and a brush card arranged to hold the brushes, the X capacitor and the Y capacitors. The brush card includes a ground portion. The X capacitor is positioned between the brushes in the circumferential direction. The Y capacitors are connected to the ground portion.

摘要： A motor includes an armature core having m×n teeth (m is an odd number ≧3, and n is a natural number ≧2), a plurality of coils, and a commutator. The motor further includes field magnets including 2n magnetic poles and at least a first-potential brush and at least a second-potential brush. The commutator includes a segment group defined by 2m×n segments. Only the coil defined by winding a continuous conducting wire in a predetermined winding direction is disposed in each of k teeth among the m×n teeth, and only the coil defined by winding the continuous conducting wire in a direction reverse to the predetermined winding direction is disposed in each of teeth disposed at a position separated from each of the k teeth at 360×i degrees (i is a natural number ≦(n−1)) of electric angles.

摘要： A motor includes a rotor, a back cover, a housing, and a brush card assembly. The rotor includes a core fixed to a shaft, a coil that magnetizes a core, and a commutator connected to the coil. The back cover includes a back cover bottom surface portion, and a back cover cylindrical portion on an outer periphery of the back cover bottom surface portion to have a cylindrical shape. The brush card assembly includes a brush card bottom surface portion spaced apart from the back cover bottom surface portion in an axial direction through a first gap. The brush card bottom surface holds brushes and includes a nip portion nipped by the back cover and the housing, an outer peripheral wall spaced apart from the back cover cylindrical portion in a radial direction through a second gap, and contact portions contacting the back cover cylindrical portion.
