ABSTRACT:
A free-wound electromagnetic yoke is formed by winding the X-axis with a continuous piece of heat bondable wire wound around a plurality of coil forms positioned on a mandrel and turned by a lathe. After winding, the mandrel is heated to cause the windings to form solid coils. After cooling, the solid coils are removed from the mandrel and from the coil forms. The same process is repeated for the Y-axis. The solid coils for both the X-axis and the Y-axis are placed in a toroidal support ring to form an electromagnetic yoke.
