Abstract: A skew correction device is provided that can easily correct the skew in the circumferential direction of the stator core arising due to insertion of electrical conductors into each slot and twisting and bending of the leading ends thereof in the circumferential direction. A skew correction device (10) for stator cores (2), includes: a support member (71) capable of supporting from outwards a protrusion (5) formed by the plurality of projecting parts (21) aligning; a first pressurizing mechanism (72) for pressing the support member (71) towards an inner side in a radial direction; and a rotation mechanism (73) for correcting skew in the circumferential direction, by causing the support member (71) to rotate in a direction in which the skew in the circumferential direction is corrected by way of a rotating shaft (731), in a state supporting the protrusion (5) from outwards by pressing the support member (71).

The rotor includes a plurality of magnets, a plurality of magnetically-assisted salient pole members provided between poles of any adjacent two magnets from among the plurality of magnets, and a magnetoresistance variation unit provided in the magnetically-assisted salient pole member along an axial direction of the rotation axis at a position offset in a circumferential direction of the rotation axis from a q-axis passing through a salient pole center of the magnetically-assisted salient pole member. The amount of offset of the magnetoresistance variation unit from the q-axis varies depending on positions of the magnetically-assisted salient pole members so that torque fluctuations cancel each other when power is applied.
