Abstract
A method of manufacturing a winding assembly for an electrical machine, the method comprising: forming, by three-dimensional, 3D, printing, an electrically insulating body comprising a channel defining a winding path, the channel having an inlet and an outlet; heating the electrically insulating body to a temperature above the melting point of an electrically conducting material; flowing 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.
