Rotor for rotary electric machine
Abstract:
A rotor for a rotary electric machine includes a pair of Lundell-type cores, a plurality of magnets, and a magnet retainer. The pair of Lundell-type cores includes a plurality of claw poles with flange portions projecting to a circumferential direction of the rotor from an end portion on an outer diameter side of each of the claw poles. The plurality of magnets are arranged between the pair of Lundell-type cores, and are magnetized in a direction of reducing flux leakage. The magnet retainer retains each of the magnets, and has side surfaces in the circumferential direction. At least one of the side surfaces is provided with at least one projection for restraining movement of the magnet retainer in an axial direction along a rotary shaft.
