摘要:
A rotary electric machine comprising a rotor (30A) including a plurality of permanent magnets having magnetic poles and a stator (20A) including a plurality of tooth sections each having a front end portion which faces the rotor, wherein the rotor (30A) has a skew structure having a change section in which boundaries between the magnetic poles change with respect to a rotation axis direction, and the front end portion of each of the plurality of tooth sections of the stator (20A) has an auxiliary slot (24A) which is selectively formed in an extending manner at one portion of the front end portion in the rotation axis direction such that substantially a center of the auxiliary slot in the rotation axis direction is opposed to a center of the change section in the rotation axis direction, and no auxiliary slot is formed at portions located on extensions of the auxiliary slot in the rotation axis direction.

A rotor includes permanent magnets arranged such that magnetic poles of N poles and S poles are arranged alternately in a rotation circumferential direction. The permanent magnets form a plurality of rows in a rotation axis direction. The rotor includes 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. A stator includes tooth sections opposed to the rotor to surround the rotor, and auxiliary slots each of which is selectively formed at one portion of 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.
