Title:
PERMANENT MAGNET-EMBEDDED ROTOR FOR ROTARY ELECTRIC MACHINE, AND ROTARY ELECTRIC MACHINE
Document Type and Number:
Japanese Patent JP2015186422
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress stress concentration on a support part while suppressing a decrease in torque.SOLUTION: A first edge 51 is extended to the side of a core inner-periphery part 27 in such a manner that a support part 28 side end of a first inner surface 41a serves as a base point, and curved to become convex toward the side of a core outer-periphery part 26. A second edge 52 is curved to become convex toward the side of the core inner-periphery part 27, on the side of the core inner-periphery part 27 with respect to a second inner surface 41b, in such a manner that a core inner-periphery part 27 side end of a connection edge 53 serves as a base point P3.
