Abstract
A rotating electrical machine comprising an armature; a yoke; and a plurality of magnets arrayed in a ring shape along an inner peripheral face of the yoke. The magnets are respectively formed in circular arc shapes fit with the inner peripheral face of the yoke, and are fixed to the yoke. The magnets are arrayed along the circumferential direction of the yoke with gaps between each other, a central portion in a circumferential direction of each of the magnets is disposed so as to be opposed in a yoke diameter direction to the gap between other magnets arrayed adjacent to each other, a boundary portion between a pair of magnetic poles in each of the magnets is positioned at central position in the circumferential direction of each of the magnets, and each of the magnets is formed thicker at end portions than at the central portion in the circumferential direction thereof.
