Abstract: A laminated core of this rotor core includes one side magnet hole provided on one side in a circumferential direction with respect to a d-axis, an other side magnet hole provided on the other side, an intermediate magnet hole, a first outer bridge portion, a second outer bridge portion, a first inner bridge portion, and a second inner bridge portion.

Abstract: The rotor includes: rotor core provided with first magnet hole on an outer side in radial direction and second magnet hole on inner side wherein radial direction for each of the magnetic poles; and plurality of permanent magnets provided in first and second magnet holes and forming magnetic poles. Rotor core includes first section provided radially outside of first magnet hole, second section extending between first and second magnet holes and having opposite ends in circumferential direction that extend to outer peripheral surface of rotor core, third section extending radially inside of second magnet hole and having opposite ends in circumferential direction that extend to outer peripheral surface of rotor core, a first bridge portion that connects second and first sections form part of outer peripheral surface of rotor core, and second bridge portion that connects third and second sections and forms part of outer peripheral surface of rotor core.
