Patent ID: 8421294

Claim:
A rotary electric machine, comprising: a rotor including a rotor iron core, permanent magnets which are arranged such that magnetic poles of N poles and S poles are arranged alternately with each other in a rotation circumferential direction of the rotor iron core and that the permanent magnets form a plurality of rows in a rotation axis direction of the rotor iron core, and a change section in which arrangements of the magnetic poles change with respect to the rotation axis direction due to the permanent magnets being arranged such that arrangements of the magnetic poles change, in the rotation circumferential direction, between the permanent magnets in the plurality of rows; and a stator including a plurality of tooth sections which are opposed to the rotor to surround the rotor, and auxiliary slots each of which is selectively formed at a front end portion of each tooth section in the rotation axis direction such that substantially a center of the auxiliary slot in the rotation axis direction is opposed to the change section, the front end portion including a face that extends continuously across the width of the front end portion from an edge of the front end portion to an edge of the auxiliary slot in the rotation axis direction.
