Abstract

A fluid-cooled magnetic element. A plurality of coils is arranged in a non-toroidal configuration. Each coil may be a hollow cylinder, formed by winding a rectangular wire into a roll. The coils alternate with planer spacers. The coils may alternate in winding orientation, and the inner end of each coil may be connected, through a connection pin, to the inner end of an adjacent coil. Small gaps are formed between the coils and the spacers, e.g. as a result of each spacer having, on its two faces, a plurality of raised ribs, against which the coils abut. Cooling fluid flows through the gaps to cool the coils.
