Abstract
Each of permanent magnets includes a magnet body formed across the radial direction of a rotor core, and a pair of magnet end parts bending toward the outer peripheral side of the magnet body and extending respectively from both ends of the magnet body in the peripheral direction toward the outer edge of the rotor core. Magnetization directions of the magnet end parts and a magnetic pole center line intersect with each other on the outer peripheral side of the magnet body. The inclination angle of each magnetization direction of the magnet end parts with respect to the magnetic pole center line is greater than the inclination angle of a magnetization direction of the magnet body with respect to the magnetic pole center line.
