Abstract

PURPOSE:To obtain molded coils having different height using single metal mold for casting by a method wherein a coil being surrounded with an insulating layer is fitted on the outer circumference of an inside wall body, it is surrounded with an outside wall body, and after a coil end face regulating fittings is inserted on the upper end of coil, a thermosetting synthetic resin liquid is poured in through the gap to mold. CONSTITUTION:A C letter shaped groove 1A is dug on the circumferential edge of the upper face of a circular end plate 1 having base metal fittings 2 on the lower face, and plural penetrating holes 1C for bolt are provided. The cylindrical inside wall body 3 with a bottom part plate 3B and an upper part plate 3C is put on this end plate 1, and the end plate 1 and the bottom part plate 3B are fixed with bolts 4 utilizing the penetrating holes 1C. Then the winding W surrounded with insulating layers I1-I4 is fitted on the outer circumference of the inside wall body 3, the outer circumference thereof is surrounded with the outside wall body 5 and the bottom part thereof is inserted in the groove 1A of the end plate 1. The upper end of the coil W exposing between the inside and outside wall bodies 3, 5 is pressed with the coil end face regulating fittings 14, and after height h of the coil is regulated, the resin liquid is poured in a vacuum through the gap thereof to be made to sink into the insides of the respective insulating layers I1-I4.
