Abstract

A rotor (1) is provided with: a rotor core wherein magnet insertion slots (2 3) radially arranged in an inwardly convex manner are disposed for each magnetic pole and the magnet insertion slots (2 3) are positioned around the circumferential direction of the rotor core according to the number of magnetic poles; and flat permanent magnets (4 5) inserted into each of the magnetic insertion slots (2 3). The innermost circumferentially adjacent magnet insertion slots (3) are configured so that the widths thereof gradually increase toward the inner side such that the width of the core between the magnetic insertion slots in the circumferential direction will be uniform in the radial direction.
