Abstract
A conductive coil for an electric application having a cooling channel for a coolant liquid or gas. The coil includes a wire winding of a plurality of wire turns. The wire winding is compressed about a cooling channel which is disposed between adjacent turn segments of the plurality of wire turns. The wire winding is formed and pressed against a shaping element to form the coolant channel within the compressed winding.
