摘要： A motor may include a stationary section and a rotating section. The stationary section may include a stator core having a plurality of teeth and a coil including a conducting wire wound around each tooth. The rotating section may include a plurality of magnets arranged radially inside the coil, a rotor core, and a magnet holder holding the magnets. Each magnet may have a circumferential end face at each of both end portions in the circumferential direction. The magnet holder may include a columnar portion axially extending between adjacent magnets, and a wall surface spreading in the circumferential direction from the columnar portion. The wall surface may come into contact with a surface arranged radially outside the circumferential end face of the magnet. The circumferential end face on at least one side of the magnet may face the columnar portion with a gap interposed therebetween in the circumferential direction.

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.
