<p>PURPOSE:To reduce the cost by forming the diameter of the load side bracket engaging portion of a frame molded with a stator and a can the same as the outer diameter of the can or slightly larger than that, thereby reducing the diameter of the frame engaging portion, thereby reducing the number of steps. CONSTITUTION:A stator core 2, a stator winding 3 and a can 4 are molded to integrally mold a frame 5. The diameter of the engaging portion 5d of the frame 5 with the load side bracket 8 is formed the same as the outer diameter of the can 4 or slightly larger than that. An annular slot 8d is formed in the engaging portion 8C of the bracket 8, an O-ring 9 is inserted in a watertight structure. A bearing 13 is engaged with the through hole 8b of the bracket 8, and a shaft 15 is rotatably supported. In this manner, the engaging portion of the frame 5 with the load side bracket 8 becomes small diameter, the accuracy after molding can be improved, the finishing machining of the engaging portion can be eliminated, thereby reducing the cost.</p> |
