Filter Influence on Rotor Losses in Coreless Axial Flux Permanent Magnet Machines
Advances in Electrical and Computer Engineering, 2013 This paper investigates the eddy current losses induced in the rotor of coreless Axial-Flux machines. The calculation of eddy currents in the magnets requires the simulation of the inverter and the filter to obtain the harmonic content of the stator ...
