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.
Claims25
An electric coil assembly comprising:
- a plurality of electrically conducting coil segments stacked together and electrically connected in series to form an electric coil, each coil segment having a first hole located at one end and a second hole located at a second end, the coil segments being directly electrically connected end-to-end, the holes of the connected ends of adjacent coil segments being aligned with each other to form aligned holes;
- and
- a plurality of fasteners extending through the aligned holes of the coil segments of the electric coil, wherein at least one of the fasteners passes through aligned holes of multiple pairs of electrically connected adjacent coil segments of the electric coil and the fasteners do not provide an electrically conductive path between any of the coil segments of the electric coil.
