Abstract
This rotating electrical machine includes: a rotor formed from stacked steel sheets and fixed to a rotary shaft; a plurality of magnets arranged on the outer circumference of the rotor along the circumferential direction; and the same number of holders as the magnets, the holders being arranged between the magnets. The holder is press-fitted and fixed into the rotor by a press-fit portion extending in the radial direction of the rotary shaft. One circumferential-direction side of the magnet is positioned by the rotor, and another side is pressed in the circumferential direction by the holder. Both circumferential-direction ends of the magnet are pressed in the radial direction by the holders. Such a configuration provides a rotating electrical machine that enables a magnet to be accurately fixed to a rotor through simple work, at low cost.
