Abstract
PURPOSE: To prevent the increase of starting currents, by restraining the decrease of leakage reactance in the case of starting by thickly forming insulating coating on the inner circumferences of the slots of a rotor core-especially, portions near to an outer circumference of the core- by inserting pipes, to which flanks holes are drilled, into said slots and by spraying insulating paints.
CONSTITUTION: A rotor core 3 is preheated at appropriate temperature, and nozzles 14 are inserted into slots 6. A number of holes for blowing insulating paints are mounted to the flanks of the nozzles 14 - eapecially, the sides 16 that face to an outer circumferential surface of the core. A fixed quantity of heat-proof insulating paints are sprayed to the inner circumferential surfaces of the slots 6 from the holes by using compressed air. This, insulating coating, which is thick and uniform and has not pin-holes, is formed on the inner circumferences of the slots 6 - especially, the upper portions 16 of the inner surfaces of the slots near to an outer circumference of the core. Aluminum die-casting is performed into the slots 6, to which insulating coating is formed in this manner, and a cage rotor is made up.
