Optimization of magnetic flux paths in transverse flux machines through the use of iron wire wound materials

This paper presents a new iron wire concept for the design of transverse flux machines with reduced losses and good magnetic properties. Previous approaches have pursued the construction of the stator from two-dimensional magnetically conductive components or alternatively SMC was used, which has poor magnetic properties. Soft magnetic materials were presented and evaluated with regard to their use as suitable material for wires. Furthermore, the paper shows the analytical calculation of eddy currents in iron wires and describes a further approach for a more precise evaluation of the losses. Eventually, measurements of iron wire samples for different diameters and heat treatment are presented.
