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.
