Summary: | The inclusion of a high energy density permanent magnet into magnetic gear
improves the machine's torque density. However, it also contributes to eddy
current loss, especially in a high-speed application such in electric vehicle. In
this paper, the losses from eddy current and iron loss are investigated on
concentric magnetic gear (CMG). Torque multiplier CMG is designed with
8/3 gear ratio for this study. Iron loss and eddy current loss are compared and
discussed. Based on this study, eddy current loss contributes to almost 96%
of the total loss. This finding is hoped to direct the researcher to focus more
on reducing loss associated with eddy current loss.
