Abstract (en)
A covered coil comprises a loop-shaped insulating tube (1) having a given length and diameter, and a coil formed by winding an insulated wire (2) through the loop-shaped insulating tube by a given number of turns, with inlet and outlet terminal sections (2a,2b) of the insulated wire, in the gap between the open ends of the tube (1). The tube (1) provides insulation and protection for the coil. The coil is made by first arranging a wire-shaped guide in the tube (1) to which the wire (2) is attached. Rolling-in rollers then rotate the guide with the wire around the tube for a desired number of turns. The covered coil is for use as a degaussing coil, a stator coil for an underwater motor, a coil for an outdoor antenna, or the like.
