Abstract
Rotor eddy current losses are analyzed for torque motors with concentrated non-overlapping windings. It is shown that eddy currents strongly depend on the winding scheme and that analysis methods correlate with rotor loss measurements. Further, it is demonstrated that magnet eddy current losses in converter-fed machines are mainly governed by the converter duty factor by studying gear-based traction drives.
