摘要： A motor having a lap winding structure and a manufacturing method therefor, wherein inserts of two different coils are installed side by side in one slot of a stator in a circumferential direction of the stator. All the coils are inserted in slots in succession. Further, a stator having semi-closed type slots formed by protuberances oriented in different directions, is used to control a reduction in the magnetic flux at the inlet of a slot and also to prevent coils from coming off. In a motor having coils of a plurality of phases for generating a rotating magnetic field at a stator, the contact portion of the coil of the desired phase among the coils of the plurality of phases and a portion rising from a slot toward the axis of a core are aligned and disposed to have a shape which prevents them from interferring with end portions of the coils of other phases.

摘要： Plural magnet insertion holes are provided at a vicinity of an outer peripheral of a laminated rotor core toward a circumferential direction and extend toward an axial direction. The magnet insertion holes are divided into plural toward the axial direction and each of the plural magnet insertion holes is shifted at a predetermined angle toward a circumferential direction. The permanent magnet is arranged in the magnet insertion hole and the permanent magnet is fixed to the laminated rotor core through a clearance fill-up agent. The cogging torque is reduced and the reduction in noises is improved and a permanent magnet rotation type rotor constituted by low cost materials is prevented from damaging or destroying by the centrifugal force.
