摘要
A motor rotor includes a rotor core having a plurality of magnet insertion holes in each of which a permanent magnet is inserted, a flow path formed on a radially inner side of the plurality of magnet insertion holes to allow a fluid to flow through, and a shaft insertion hole in which a rotary shaft is inserted, and the permanent magnet inserted in each of the plurality of magnet insertion holes of the rotor core. The rotor core has an inlet opening and an outlet opening each opened in a corresponding one of end faces of the rotor core in an axial direction, and a communication hole circumferentially extending inside the rotor core and communicating with the inlet opening and the outlet opening.
