摘要： The device comprises a single circular row of permanent magnetic poles and a circular row of electromagnets, magnetic-force-conducting elements of which have central polar part and two lateral polar parts connected to the central polar part and spaced from opposing (in the direction which is essentially perpendicular to the rotation axis) sides of the central polar part. Winding is situated upon central polar part. The part of winding positioned between the polar parts of the magnetic-force-conducting element is more than half the length of the whole winding. Central polar part may have at least one groove. The distance between the centers of adjacent polar surfaces of the magnetic-force-conducting element is set depending on the angle between the magnetic poles in the circular row. The angular dimension of the polar surface of the lateral polar part depends on the angular dimension of the polar surface of the central polar part.

摘要： There is provided a rotating electric machine capable of reducing torque pulsation, even when a slight stepped portion is present in an inner diameter shape of a stator core formed by allowing split cores divided in every magnetic pole to be in an annular shape. The stator core is formed by stacking a plurality of laminates prepared by stack of split core members formed by punching steel sheets and arranged in an annular shape in a state where the laminates are rotated one another by a predetermined angle. With such a configuration, it is possible to mutually offset torque pulsation components caused by the shape asymmetry of the laminates and reduce the torque pulsation components of the stator core on the whole.
