Abstract
A bipolar rotor of a rotating electric machine is such that flexural rigidity asymmetry of a rotor main portion is adjusted using a cross slot provided in a rotor core, and flexural rigidity asymmetry of a rotor stepped portion is adjusted using a cutout groove provided in the rotor stepped portion, whereby optimization is achieved by combining the flexural rigidity asymmetry of the rotor main portion and the flexural rigidity asymmetry of the rotor stepped portion, and vibration in each double frequency vibration flexural vibration mode is restricted over a whole region of driving rotational speed.

1-11. (canceled)
A rotor of a rotating electric machine, wherein at least one cutout groove is provided in a rotor stepped portion, in an axis of rotation direction of the rotor stepped portion, in such a way that a flexural rigidity around an in-polar axis is adjusted, and a flexural rigidity around an interpolar axis and the flexural rigidity around the in-polar axis have asymmetry.
