Abstract

A method of making a component of a radial or axial flux electrical machine is provided. An additive manufacturing process is used to manufacture a plurality of laminas, including applying beams of energy to a successive plurality of ferromagnetic material particles and fusing them together to form a ferromagnetic helix or spiral, disposing an insulating material on said ferromagnetic helix or spiral, compressing the ferromagnetic helix or spiral to form a compressed ferromagnetic helix or spiral, and fixing the compressed ferromagnetic helix or spiral. A method of making a component of a transverse flux electrical machine is provided, including using an additive manufacturing process.
