Abstract
In one aspect, the present invention provides an air coil 20. The air coil 20 may be made from a strip of electrically conductive material 22 which has an insulating material overlying it. For example, the conductive material may comprise copper. The strip 22 is wound into a coil to perform a plurality of windings. The insulating material electrically insulates each of the winding from adjacent ones of the windings.
Claims14
A method of making an air coil comprising the steps of:
- providing a sheet of conductive material;
- disposing an insulating material adjacent said sheet of conductive material;
- cutting said sheets of conductive material and insulating material into a plurality of strips;
- and
- winding each strip into an air coil such that each air coil comprises a plurality of windings wherein said insulating material electrically insulates each of said windings from adjacent ones of said windings.
