Abstract

PURPOSE:To manufacture a resin-molded coil without using a mold by energizing to heat a strand coil before exhausting it from a resin tank to increase the viscosity of the resin in the strand coil or make the resin gelled. CONSTITUTION:After manufacturing a strand coil, resin is immersed to the coil in a resin tank. After the immersion, the coil is energized before exhausting the coil from the resin tank to increase the viscosity of the resin in the strand coil or gel the resin. Thereafter, the coil is exhausted from the resin tank, is set in a rotating unit, and is heated or energized to be heated or both heated and energized to rotatably cure the resin. Or, ultraviolet ray curable resin is used as the immersed resin, and ultraviolet rays are irradiated to the strand coil immersed with resin to form a coating on the surface of the coil. Then, the coil may be rotated to cure the resin immersed in the coil. In this manner, there can be manufacture a resin-molded coil having high performance without using a mold nor sacrificing the yield of the immersed resin.
