Insulated coil and coiled frame and method for making same

DETAILED DESCRIPTION A preferred embodiment of the present invention substantially avoids the aforementioned difficulties associated with the assembly and use of conventional coils and coiled frames.
Generally speaking, this embodiment relates to an insulated coil for use in a coil and pole assembly intended for installation in a magnet frame.
The insulated coil comprises an electrically conductive coil having a frame side and a pole side and including a plurality of aligned, overlapping turns that form a pole opening.
Each of the coil turns includes an outer surface that is to be insulated from each other.
To provide for this insulation, the coil further comprises a powder coating material that is disposed on the outer surfaces of the coil turns.
Normally, the electrically conductive coil has been compressed to a desired dimension and the powder coating material cured while the coil is in the compressed orientation such that the electrically conductive coil permanently remains in the desired orientation.
In addition, a preferred embodiment of the present invention relates to a method for insulating an electrically conductive coil for use in a coil and pole assembly.
The method comprises the steps of coating the electrically conductive coil with a powder coating material, heating the powder coated coil a first time to partially cure the powder coating material, fitting the powder coated coil about a pole, compressing the powder coated coil about the pole, and heating the powder coated coil a second time while in the compressed state to completely cure the powder coating material.
The objects, features, and advantages of the invention will become apparent upon reading the following specification, when taken in conjunction with the accompanying drawings.
