Abstract:
(EN)
This invention comprises a rotor, which includes a rotor core and magnets inserted into the rotor core, and a stator provided around the rotor core. The rotor core includes a shaft hole into which a shaft is inserted, and magnet insertion parts into which the magnets are inserted, the magnet insertion parts extending parallel to the direction of the rotation axis of the shaft and having an elongated shape in cross-section orthogonal to the direction of the rotation axis. The magnets include an outer peripheral surface in contact with a magnet insertion part of the rotor core. The magnet insertion parts include a projection projecting towards a magnet, the projection being formed on a longitudinal end part of the magnet insertion part in a cross-section orthogonal to the direction of the rotation axis. The projections include a top part in contact with the outer peripheral surface of a magnet and a set-apart part set apart from the outer peripheral surface of the magnet.
(FR)
La présente invention comprend un rotor, qui comprend un noyau de rotor et des aimants insérés dans le noyau de rotor, et un stator disposé autour du noyau de rotor. Le noyau de rotor comprend un trou d'arbre dans lequel un arbre est inséré, et des parties d'insertion d'aimant dans lesquelles les aimants sont insérés, les parties d'insertion d'aimant s'étendant parallèlement à la direction de l'axe de rotation de l'arbre et présentant une forme allongée en coupe transversale orthogonale à la direction de l'axe de rotation. Les aimants comprennent une surface périphérique externe en contact avec une partie d'insertion d'aimant du noyau de rotor. Les parties d'insertion d'aimant comprennent une projection faisant saillie vers un aimant, la projection étant formée sur une partie d'extrémité longitudinale de la partie d'insertion d'aimant dans une section transversale orthogonale à la direction de l'axe de rotation. Les projections comprennent une partie supérieure en contact avec la surface périphérique externe d'un aimant et une partie espacée disposée à distance de la surface périphérique externe de l'aimant.
