Abstract
An electro-magnetic coil with coolant permeability wound using insulated wire includes a plurality of radially arranged layers and a plurality of axially arranged turns of the insulated wire per layer, wherein the insulated wire has a plurality of sections along its length with different cross-sections for any pair of two adjacent sections that collectively form into axial and radial coolant channels as the wire is wound around a core.

An electro-magnetic coil with coolant permeability wound using insulated wire, the electro-magnetic coil comprising:
- a plurality of radially arranged layers of the insulated wire, and
- a plurality of axially arranged turns of the insulated wire per radially arranged layer,
- wherein the insulated wire has a plurality of sections along a length thereof with different cross-sections for any pair of two adjacent sections such that empty spaces formed by the axially- and radially-adjacent cross-sections of insulated wire collectively form coolant channels;
- wherein adjacent sections comprise a local wire deformation being coordinated with the tangential position on the coil and thus creating cooling channels in axial and/or radial direction in a coordinated way;
- and
- wherein the coil has a core on which the wire is wound, where l=2*pi*t, where l is the length of the periodic pattern, and t is the maximum thickness of the wire, with pi being Ludolph's number, wherein l is a divider of the circumference of the core on which the wire is wound, so that deformed and un-deformed sections between windings in the same layer align.
