• Resumen

  • Purpose – The purpose of this paper is to describe the optimization process of a homopolar machine. The work has been focused on a reduction of axial forces acting on the rotor.

    Design/methodology/approach – A novel machine design has been proposed and a detailed FEM analysis has been performed.

    Findings – The source of the axial force in the homopolar machine has been indicated and a new method of axial force reduction has been presented.

    Originality/value – A detailed comparison shows that the applied changes lead to a significant axial force reduction and allow the usage of cheaper and less prone to axial forces bearings.
