To prevent seizure of a bearing or the like due to generation of hydrogen gas caused by corrosion at an aluminum section, such as an aluminum rotor bar in a fluid including motor, and to improve the efficiency and reliability of the motor.

This fluid including motor uses a sealed fluid 27 in the motor inside 6 and includes the aluminum rotor bar 28 of the rotor 13, and a fluorocarbon inert fluid, such as hydrofluoroether, is used as the sealing fluid 27.
