Abstract

PURPOSE: To form slot insulation films necessary for a rotor of a squirrel-cage motor simole, by dip coating the peripheral slots of a laminated iron core which is being rotated on rollers in a coating tank.
CONSTITUTION: The temporary shaft 4 is inserted into the shaft hole 4a to tighten the iron plates temporarily. The laminated iron core 3 is preheated and placed on the support rollers 8 in the coating tank 7 filled with a heat-resistant insulating coating material to dip only the bottom slots 5 under the liquid level 11. The core 3 is rotated and dipped in the coating material in a short time, then dried in the air by heating with the heat source 9. The procedure is repeated, and the core 3 is rotated in the directions of arrows A and B by turns to form films of uniform thickness on the parts 5a and 5b of the slots 5. The excess coating material is scraped off by the plate 10 in contact with the periphery of the core 3.
