Abstract

PURPOSE:To increase the strength of a water-soluble core for forming a ventilation clearance and improve the accuracy of size, and to ameliolate working property by arranging a burning foamed styrol model to a conductor section while holding a silicon steel plate from upper and lower sections and molding the core when manufacturing the core. CONSTITUTION:The silicon steel plate 3 is set onto a surface plate 10 while the burning model 12 made of foamed styrol is set at the position of space for casting the conductor, a residual section is filled with a water-soluble core material, the silicon steel plate 3 and a surface plate 13 are set from the upper section, and the rotor is molded by a press. The surface plates 10, 13 are removed, the model 12 is burnt, and a water-soluble ventilation clearance molding piece 1 held by the silicon steel plates 3 is obtained. The ventilation clearance molding piece 1 is laminated together with the silicon steel plates 3 and a core 4 is manufactured, a die 5 is applied and the conductor 2 is casted. Lastly, the water-soluble molding piece 1 is removed through washing by water, and the casted rotor with the ventilation clearance is obtaind at a position where there was the molding piece 1.
