Abstract
A rotor includes a rotor core fixed to a shaft, a pair of magnet slots arranged in a V-shape in the rotor core so as to be separated away from each other toward a radially outer side, permanent magnets inserted into the magnet slots, and a hole provided on the radially outer side of the magnet slots. The distance between each permanent magnet and the hole increases toward the radially outer side. The distance between an outer circumference of the rotor core and the hole is not less than the distance between each magnet slot and the outer circumference of the rotor core.
