摘要：A void group made up of plural voids is formed on an outer circumferential sideof a longitudinal end portion of a permanent magnet provided in a rotating electricmachine rotor. The void group includes a first void and a second void row where pluralsecond voids are formed at predetermined intervals at a position further radially
outwards than the first void. A rib is formed between a pair of adjacent second voids ofthe second void row. End portions of the first void respectively overlap the pair ofadjacent second voids. An imaginary line that extends along the center of the rib passesthrough at least part of the first void. A magnetic pole center-side end portion of thevoid group extends from the outer circumferential surface of the permanent magnettowards an outer circumferential surface of a rotor core.
