Abstract

The paper presents a study of a magnetic gear (MG) used for high speed appli- cations (26000 r/min); its performances are numerically evaluated. Against common mechanical gears, for which the high trasmission ratio at high power is obtained only by linking several gears, the MG offers a better power density since just one unit can be used (even for high pow- ers), and with acceptable levels of ripples in the torque wave. The paper investigates also the use of different magnet materials, other than the very expesive rear-earth ones, to evaluate the MG’s performances. It is clear that the main loss source on a MG is the iron loss component, which is affecting directly its efficiency. Thus, the use a different core meterials will be considered for a final evaluation of the MG’s operation to decide on the obtained performances: power density and efficiency.
