Abstract
Instead of being made from one continuous piece of material, a coil includes multiple flat coil segments that are stacked together and electrically coupled in series. In many embodiments, the coil segments are U-shaped segments, and the segments are arranged so that each segment is rotated (e.g., by 270 degrees) with respect the segment it follows. The stacked coils may then be fastened together using, for example, bolts through the corners of the coil segments. The combined coil segments form a continuous coil.
Claims7
A method of manufacturing an electric coil assembly, said method comprising:
- obtaining a plurality of electrically conducting coil segments, wherein each coil segment of the plurality of coil segments has a first hole located at one end and a second hole located at a second end;
- stacking the plurality of electrically conducting coil segments together to form an electric coil in which the plurality of electrically conducting coil segments are electrically connected together end-to-end and in series with the holes of the connected ends being aligned with each other to form aligned holes;
- and
- holding the stacked coil segments together with a plurality of fasteners extending through the aligned holes of the coil segments of the electric coil, wherein said plurality of fasteners do not provide any electrically conductive paths between any of the coil segments of the electric coil.
