  • Patent number: 10069362
    Abstract: In a rotating electrical machine, in the case where a cylindrical component is fixed by press fitting or the like, the opening edge of the cylindrical component is widened toward the end to provide peeps for facilitating the insertion of the cylindrical component. However, the outer shape of a rotor expands due to the peeps, and a gap needs to be provided between the rotor and a stator in consideration of the expanded portion of the outer shape, which causes the degradation of the performance of the rotating electrical machine. In addition, in the case where magnets are fixed only by the tightening force of a magnet cover, the greater the centrifugal force becomes, the larger the clamping margin becomes and similarly the larger the peeps become, and thus the expanded portion also becomes larger. However, if the opening edge is not widened to the end, the absence of the peeps makes it difficult to insert the magnet cover.
