Abstract

PURPOSE:To prevent the leakage of aluminum melted in a ventilating duct section while improving working property by mounting a space piece manufactured by integrally forming the ventilating duct, in which a plurality of slots of the outer circumference of an end plate are drawn out only by duct width, to the end plate. CONSTITUTION:A plurality of holes of the outer circumference of the end plate 5b of a rotor duct section are formed by molding projecting holes 18 each drawn out in the similar figures of a plurality of the core slots 2 of the outer circumference of a rotor iron plate and the end surface 19 is flatly formed, and a stratiform core 12g is mounted which is shaped by each inserting the space pieces manufactured by integrally molding annular space rings 10d, which are formed by drawing out the outer circumference of a hole 4 with a key way passing the central section shaft of the end plate 5b only by the duct with H, among core blocks 5a. Accordingly, the leakage and coagulatin of aluminum melted in the ventilating duct 7 section, the reduction of the area of ventilation and the gen eration, etc. of the crack of the aluminum conductor section of a slot duct section are prevented, and working property can be improved.
