Method for making multiconductor coil and the coil made thereby

Abstract

The method of the present invention is used to make a multiconductor coil having an outer diameter equal to the diameter of a winding mandrel plus the diameter of wires being coiled while preserving homogeneity of the insulating coating and of the insulation between the wires. The method includes the steps of: winding a first uninsulated wire conductor on a winding mandrel with a predetermined spacing between adjacent turns of the coil of wire conductor; coating the uninsulated coil of wire conductor with an insulating coating; repeating the above two steps for each additional wire conductor to be included in the multiconductor coil; and, after the insulating coating on each wire conductor coil has dried and/or solidified, screwing each additional coil into the first coil to form a multiconductor coil having a desired homogeneity of the insulating coating and of the insulation between adjacent turns in the multiconductor coil.
