N2 - Unlike in low-speed machines, frequency-dependent phenomena in very-high-speed machines ¿
skin- and proximity effect, eddy currents ¿ may greatly influence copper losses. To alleviate these
phenomena, parallel or stranded conductors are commonly used. Goal of the paper is to distinguish
dominant causes of copper losses in slotless PM machines and, based on modeling, to establish a method
for optimization of stator conductors ¿ number of parallel wires/strands within a phase conductor and their
diameter ¿ for a minimum copper loss. Effectiveness of the modeling and optimization approach is
evaluated using finite-element simulations.
