PURPOSE:To prevent the insulators of a canned motor from deteriorating by integrally forming a through hole part for engaging a bearing of an opposite load side and an exhaust plug when forming a frame by molding a stator and a can, thereby forming a bracket and reducing the number of components. CONSTITUTION:The end of an opposite load side is extended in L shape in section when forming a frame by molding a stator core 3, a stator winding 4 and a can 5 with a molding material, a coupler 1f engaged with a bearing 8 is formed to omit a bracket. An exhaust plug 15 is screwed by a male screw 15a to the female screw 1g of a frame 1 in a watertight manner with O-rings 16. A shaft 14 is rotatably supported via a bearing 8. The shaft 14 is rotatably supported through a load side bracket 10 and a bearing 11, and watertightly sealed between the frame 1 and the bracket 10 with O-rings 12. In this manner, the structure of the opposite load side is omitted to reduce the cost. |
