Abstract
A random-wound winding for an electrical machine including interconnected wire layers, wherein the interconnected wire layers include randomly wound wires and are configured upon placement in the electrical machine to have substantially the same impedance. Accordingly, the random wound windings can include a first coil having layers of wires randomly wound on the first coil with the layers configured in a first layering order, a second coil having layers of wires randomly wound on the second coil with the layers configured in a second layering order transposed relative to the first layering order, and at least one electrical interconnection configured to serially connect the layers of the first coil to the layers of the second coil such that an average axial position of all interconnected layers is substantially the same. The random wound windings can include a coil having layers of wires randomly wound on the coil with one side of the coil having the layers configured in a first layering order and an opposing side of the coil having the layers configured in a second layering order transposed relative to the first layering order, wherein an average axial position of the layers substantially the same.
