<P>PROBLEM TO BE SOLVED: To provide a rotor for a rotary electric machine which has a structure capable of suppressing dislodgment of permanent magnets from magnet storage spaces irrespective of centrifugal force during rotor rotation. <P>SOLUTION: A magnet storage space 6 is formed to store a permanent magnet 5, and a magnet outer end void 61 is formed in continuity with the magnet storage space at an outer end of pole face extension, that is, a core-radially outward end of pole face extension. The magnet storage space has an outer-pole-parallel wall surface 53 parallel with an outer pole face, which is a core-radially outward pole face of the permanent magnet. The magnet outer end void has a void outer wall surface 63 continuously extending from the outer-pole-parallel wall surface. A magnet pressing projection 9 projecting not toward the outer pole face but toward an inner pole face in a direction perpendicular to pole face extension is formed at a boundary portion between the magnet outer end void and the magnet storage space. <P>COPYRIGHT: (C)2012,JPO&INPIT |
