The invention relates to the field of electrical engineering and can be used in the manufacture of electric motors and other electromechanical devices with a baseless active zone printed methods. To improve manufacturability and expand functionality, a blank is formed that includes the required number of insulated printed conductors on the surface of the flexible base, bend the resulting board 180 ° at least once before receiving the trapezoidal board, roll the latter into the cylinder across the bend lines and electrically connect the ends of the conductors . The printed conductors are formed with alternating main sections and areas of reduced width, along which the blank is bent. This allows you to completely eliminate the incident error when kinking, the lines of which are self-aligned in this way with the conductor pattern, regardless of the accuracy of the base of the board on the tooling. It is advisable to form the insulation of printed conductors of such an anchor before bending the workpiece by overlaying dielectric material from opposite sides of printed conductors located on adjacent main sections. In another embodiment, used in the manufacture of a bipolar armature, the insulation is formed in the process of bending the workpiece by wrapping it with a film dielectric material with double-sided adhesive properties. The third option, which allows to obtain the highest possible utilization of the wrapping layer, is that the insulation is molded before the formation of printed conductors by placing a layer of dielectric material between two layers of a flexible metal base, and then forming printed conductors with their overlapping main sections located on opposite sides of layers of flexible base.
