A stator for a motor is a segmented type including a plurality of stator segments. Each stator segment includes a core segment forming a stator core, a stator winding including a first winding wound in one direction on the core segment, and a second winding wound in the opposite direction on the core segment, and an insulating member interposed between the core segment and the stator winding. A connecting member is formed integrally in the insulating member, and arranged to electrically connect inner ends of the first and second windings to form a single continuous winding.
