Abstract

In this paper, finite element method simulations and frequency analysis of additively manufactured windings with a Hilbert-cross section pattern were performed over a wide frequency range. The current density distributions for the proposed winding conductor and for a square-wire winding conductor at selected frequencies were compared. An approximately 25% winding loss reduction at higher frequencies and an approximately 5% increase at low frequencies were observed for the analyzed Hilbert structure.
