摘要： A motor includes a shaft, a rotor, a stator, and a housing. The stator preferably includes a core including a plurality of teeth, a plurality of coils, and electrically insulating tubes. The core is defined by a combination of a plurality of unit cores each of which has a separate one of the teeth. The plurality of coils include two or more continuous coils defined by a single line of a conductor wire. Each of the electrically insulating tubes is arranged to cover at least a portion of the conductor wire which passes between the continuous coils.

摘要： An armature includes a core-back, insulator members, coils and insulating sheets. The insulating sheets are arranged between the coils adjacent to one another. Each of the insulator members includes a flange-shaped inner wall portion positioned radially inwards of each of the insulating sheets. The inner wall portions of the insulator members adjacent to each other include opposing portions opposed to each other in a radially spaced-apart contactless relationship.

摘要： A stator unit including a coil in which a distance between an m−1-th turn and an m-th turn is wider than each distance in a first turn to the m−1-th turn. The m+1-th turn is disposed between the m−1-th turn and the m-th turn. Further, in a cross-section perpendicular to a central axis and passing a tooth, an angle between a line segment connecting respective centers of the m+1-th turn and the m−1-th turn and a line segment connecting respective centers of the m+1-th turn and the m-th turn is about 120° or more. With this structure, bulging in a circumferential direction of the coil adjacent to an inner peripheral portion of the tooth can be suppressed and a clearance can be secured between adjacent coils such that the number of turns of the coil can be increased.
