Claims (3)

The stator iron core that forms the same number of slots as the tooth portions by a plurality of tooth portions and the yoke portion of the outer peripheral portion, and the number of slots that integrally forms the tooth portion and a part of the yoke portion of the outer peripheral portion. The divided iron cores A are divided into the same number of divided iron cores A, and the divided iron cores B are connected to each other to form a yoke part that connects the adjacent divided iron cores A to form a magnetic path on the outer periphery. The core body A is formed by punching a directional electrical steel sheet having a property of being easily magnetized in a radial direction perpendicular to the rotor axis and laminating it in the circumferential direction, and the divided iron core body B has a magnetic powder in a predetermined shape. The rotor is formed of a powder magnetic core formed by molding, and the split laminated body A is formed so that the axial length is longer than the other portions at the joint surface with the rotor facing surface and the split iron core B. After the winding is wound around each tooth by concentrated winding in a state of being arranged radially around the hole, or the divided iron core After arranged so as to form a radially around the tooth portions of the windings mounted on the rotor hole of A, the divided iron core member B and the capacitor motor configuration in which the assembly and integration of coalesced stator a. Divided iron core A becomes to punching and laminated in the same shape, capacitor motor according to claim 1 of configuration disposed with a gap of approximately the same size relative to the rotor iron core outer circumference. The divided iron core B is divided into two in the direction perpendicular to the rotor shaft to form divided iron cores Ba and Bb, respectively, and the divided iron core A and the slot on the periphery of the divided iron core Ba and / or Bb. Assembling of the stator is performed by providing a mounting portion at a position equally divided by the number, and by combining the outer peripheral side tip portion of the divided iron core A from above and below by the mounting portion of the divided iron core Ba and / or Bb. The capacitor motor according to claim 1 or 2 , wherein the capacitor motor is integrated.
