PURPOSE:To facilitate the inspection, research, maintenance and repair of a liquid-cooling passage by cnnecting the ends of connecting tubes arranged between the assembling ring of cooling liquid and stator coils in a cap nut type, thereby facilitating the attachment and detachment of the tube. CONSTITUTION:A connecting tube 3 made, for example, of a flexible insulating tube is arranged between the assembling ring 2 of cooling liquid and stator coils 4. A cap nut 6 is provided at the end of the tube 3, a projection 8 is formed partly on the outer periphery of the tube 3, and threads are formed on the outer periphery of the joint 7 of the ring 2. A packing 11 is inserted between the nut 6 and the joint 7, and the tube is connected to the ring in a cap nut type. The tube 3 is connected to the coils 4 in the similar cap nut type. |
