ABSTRACT:
A liquid-seal type motor comprising a cylindrical frame, a stator fixed inside the frame, a can placed at the inner circumferential side of the stator, a pair of end plates placed at both ends of and between the frame and the can to be sealingly connected thereto to thereby form an insulating oil enclosing part in which the stator is confined, a pair of brackets connected to the pair of the end plates respectively and a rotor placed in the can to be journaled by the brackets. The can, the brackets and the rotor define a lubricating oil enclosing part. A pressure adjusting means has a flexible member for sealingly defines the insulating oil enclosing part into two parts and an oil volume reducing member is provided in the insulating oil enclosing part.
