Title:
LIQUID-SEALED MOTOR
Document Type and Number:
Japanese Patent JPS6028743
Kind Code:
A
Abstract:
PURPOSE:To prevent the temperature rise around a stator and to suppress the pressure rise in a can by providing a pressure regulating member between a frame and a can, and connecting the both side ends of the stator via a connecting slot. CONSTITUTION:When insulating oil B around a stator 2 largely expands due to temperature rise, the expansion of the volume is released through the hole of a case 25 into the case 25, and an elastic material in the case 25 is inwardly compressed. Thus, the pressure difference between the interior and the exterior of the can 3 is almost eliminated. A connecting slot 33 is formed at the inner periphery of a frame 1, insulating oil B is circulated at both sides of the stator 2, the temperature rise of the stator 2 can be suppressed, and the expansion of the volume at the upper side of the periphery of the stator 2 can be absorbed by the elastic material in the case 25 through the slot 33.
