MANUFACTURE OF SQUIRREL-CAGE ROTOR
Document Type and Number:
Japanese Patent JPS58201563
Kind Code:
A
Abstract:
PURPOSE:To prevent the production of cavities and the invasion of molten conductor material into between laminated steel plates by obliquely providing inlets to fill the molten material in the same direction as the skew of a core. CONSTITUTION:A plurality of inlets 7 are arranged circumferentially at a core 2. The inlets 7 are formed obliquely in the same direction as the skew of a core 2. When a molten conductor material such as so-called ''molten metal'' is filled from the respective inlets 7 to the part of the core 2, the molten metal is introduced from the axial one end side of the core 2 through the respective slots 9 to the other end side, thereby forming conductors disposed in the respective slots 9 and end shortcircuit rings which shortcircuit at both ends of the conductors.
