Abstract
A rotor includes a shaft, a rotor core including a pair of accommodation holes, and a pair of magnets accommodated in the pair of accommodation holes. The pair of magnets extend in directions away from each other in a circumferential direction from the radially inside toward the radially outside. A flux barrier is radially outside the magnet. The rotor core includes a first gap between magnetic poles adjacent to each other in the circumferential direction. The first gap is sandwiched between the flux barriers of the magnetic poles adjacent to each other in the circumferential direction. A radially outside surface of the rotor core includes a pair of core recesses provided in a portion located on the radially outside of the flux barrier and a core protrusion located between the pair of core recesses in the circumferential direction.
