Original Abstract Submitted
A rotating electric machine includes a stator and a rotor. A magnetic pole of the rotor includes a magnet hole, a permanent magnet, a first void portion, a second void portion, and a rib. The magnet hole extends so as to cross a magnetic pole centerline in a circumferential direction and is formed in substantially an arc shape when seen in an axial direction such that both end portions approach an outer circumferential edge portion of the rotor. The first void portion is formed between both end portions of the magnet hole in an extension direction and the permanent magnet. The second void portion extends separately from the magnet hole on extension of both end portions of the magnet hole in the extension direction. The rib connects an outer region and an inner region of the first void portion and the second void portion in a radial direction.
