Abstract
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.
