ROTOR HAVING FLOW PATH OF COOLING FLUID AND ELECTRIC MOTOR INCLUDING THE ROTOR

摘要

A rotor is formed with a flow path for supplying a cooling fluid. The flow path has a supply path extending inside the rotor, a plurality of branch paths branching off from the supply path, and return paths extending from the respective branch paths toward a base end side of the supply path. The branch paths are at positions distant from each other in a direction parallel to a rotational axis of the rotor.
