<P>PROBLEM TO BE SOLVED: To provide a rotary electric machine that can suppress reduction in force to rotate a rotor core (magnetic torque or main magnetic flux) while suppressing irreversible demagnetization of permanent magnets. <P>SOLUTION: A rotary electric machine 100 includes a rotor core 21, and permanent magnets 23 buried in the vicinity of an outer circumferential portion of the rotor core 21, and has clearances 25 for suppressing irreversible demagnetization of the permanent magnets 23 on portions of the rotor core 21 on an inner circumferential surface side of the permanent magnets 23 and in the vicinity of the inner circumferential surfaces of the permanent magnets 23. <P>COPYRIGHT: (C)2012,JPO&INPIT |
