Abstract
A permanent magnet rotating electrical machine includes a stator and a rotatable, approximately cylindrical rotor. The rotor includes a shaft, rotor cores, radial permanent magnets, and side plates. The shaft includes projected and depressed engagement portions. The rotor cores are separated from each other on a magnetic pole basis. The rotor cores constitute circumferentially arranged pole shoes. The radial permanent magnets are each on a circumferential side of a pole shoe among the pole shoes. Each of the radial permanent magnets is engaged with an engagement portion among the engagement portions of the shaft. The side plates are on axial ends of the rotor. The side plates support the rotor cores and the permanent magnets in a radial direction of the rotor.
