Abstract [en]

The complex three-dimensional fluxes in a newly introduced high-performance transverse-flux electrical machine are investigated. The magnet-flux, the armature-flux and the combined-flux in the machine are studied as a function of mover position. Separate non-linear reluctance networks for the magnets- and current- magneto-motive forces are developed and solved simultaneously in an iterative manner. The airgap is modelled by defining two/three-dimensional varying permeances. The iron is represented with three different non-linear reluctances. The analytical models are fine tuned and verified by employing a detailed three-dimensional finite element analysis. The role these fluxes play in the determination of the machine's performance is also described. Lastly, it is shown how these fluxes help explain the machines' measured performance when unexpected manufacturing defects occurred.
