。 A shaft to which a rotor with an end ring is fixed is inserted into the outer shell, and a stator is placed through the rotor through a narrow gap, and the space for housing both is made into a cylindrical can. In the liquid-sealed electric motor, the shaft is provided with a structure in which a liquid such as lubricating oil is sealed between the two, and the liquid sealed in the rotor side space is circulated to the surface of the outer shell for cooling. A liquid ring type electric motor, characterized in that a balance ring is attached to the side opposite to the rotor from the end ring, and a spiral groove is formed in at least one of these rings to assist the flow of the sealed liquid in the circulation direction.
