Abstract

PURPOSE:To form the captioned rotor duct part free from shrinkage cavities by inserting molten metal plates opened with slot holes in the plural duct parts between rotor laminated iron cores by way of the iron plates provided with slot holes and laminating and clamping then pouring Al. CONSTITUTION:Spacing plates 1 mode of zinc alloy of a melting point lower than that of casting Al conductor are inserted between rotor laminate iron cores 2 and the laminate iron cores 9 parts comprising laminating plural sheets or rotor iron plates 2C formed with slot holes 6B opened with the circumferential edge parts of the iron plate slot holes of the iron cores 2 are inserted and clamped to both surfaces thereof and molten Al is poured to form bars 4, end rings 10 and duct conductor parts 5. Next, the spacing plates 1 are dissolved away, whereby the duct parts 3 of the cast cage type rotor are provided. The air included together with Al is escaped through the opening parts of the slot holes 6B and the shrinkage cavities and shrinkage crack at the root part of the bars 4 and duct part 5 which have higherto been occured are prevented.
