摘要： The present invention realizes reduction in vibration and noise while utilizing reluctance torque. A rotating electrical machine of the present invention includes: a rotor in which a plurality of permanent magnets are disposed in a cylindrical surface coaxial with a rotary shaft; and a stator having a annular stator core disposed coaxially with the rotary shaft, and a annular coil for magnetizing the stator core. The stator core has a annular part covering the annular coil, a plurality of claws disposed at equal intervals in an inner radius surface of the annular part and extending in the axial direction, and a plurality of magnetic gaps formed between the neighboring claws. The number of the claws is equal to the number of permanent magnets, and magnet flux in a direction orthogonal to a center axis direction of the magnetic pole of the permanent magnet at right angles in electric angle is larger than magnetic flux in the center axis direction generated between the neighboring permanent magnets. To realize the configuration, metal interpoles are provided between the neighboring permanent magnets.

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.
