Abstract:
1. An electric rotating machine comprising: a stator; and a rotor that is rotatably disposed with respect to the stator, the rotor including a rotor core that has a plurality of slots formed therein and a plurality of permanent magnets each of which is received in a corresponding one of the slots of the rotor core, wherein: wherein: wherein the first supporting portion about and thereby supports a third corner portion-side end portion of the first side surface of the permanent magnet in the reference direction of the permanent magnet, the third corner portion-side end portion of the first surface having a width in the magnetization direction of the permanent magnet which is not greater than half a width of the entire first side surface in the magnetization direction, and wherein the second supporting portion abuts and thereby supports a fourth corner portion-side end portion of the second side surface of the permanent magnet in the reference direction of the permanent magnet, the fourth corner portion-side end portion of the second side surface having a width in the magnetization direction of the permanent magnet which is not greater than half a width of the entire second side surface in the magnetization direction.
