Abstract
A rotor includes a rotor core and a permanent magnet. The rotor core includes an outside slit provided between a permanent magnet insertion hole and an outer peripheral surface of the rotor core, and inside slits provided between a magnetic pole center part and the outside slit. A minimum distance from a first inside slit to the outer peripheral surface of the rotor core is longer than a minimum distance from any other inside slit except the first inside slit to the outer peripheral surface of the rotor core.
