Abstract
A method of manufacturing a winding assembly for an electrical machine, the method comprising: selecting (S) a mathematical function defining the spatial separation between adjacent turns of a winding path, the mathematical function dependent on one or more parameters of the electrical machine and/or of the anticipated operating environment of the electrical machine; forming (S), by three-dimensional, 3D, printing, an electrically insulating body comprising a channel defining the winding path in accordance with said function, the channel having an inlet and an outlet; heating (S) the electrically insulating body to a temperature above the melting point of an electrically conducting material; flowing (S) the electrically conducting material through the inlet to the outlet to fill the channel; and cooling the electrically insulating body to solidify the electrically conducting material within the channel, thereby forming said winding assembly.
