Abstract

PURPOSE: To manufacture high-quality coil inexpensively by covering a heat shrinking tube around the outer surface of a coil have been wound, forming a leakage-preventing layer on the outer surface of the coil by heat-shrinking after resin impregnation, and curing the resin.
CONSTITUTION: The outer surface of a coil 1 is covered by a heat-shrinking tube 20, and said assembly is put in a resin-impregnating tank 21, in which resin composition is impregnated. A resin-leakage-preventing layer is formed around the coil 1 by blowing hot air or illuminating infrared ray to the outer surface of the coil 1 which is being rotated, and by shinking the heat-shrinking tube 20. After the shrinking of the heat-shrinking tube 20 has been completed, the coil 1 is taken out of the impregnating tank 1, the impregnated resin is cured, the heat-shrinking tube 20 is removed, the impregnated-resin-leakage preventing layer 14 on the end surface of the coil 1 is removed by cutting machining, thereby resin-impregnated electromagnetic coil is manufactured.
