回転電機
Document Type and Number:
Japanese Patent JP5171224
Kind Code:
B2
Abstract:
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 coupling 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 coupling split core members formed by punching steel sheets in an annularly arranged 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.
