Analytical prediction and analysis of the detent force with the feedback harmonics for the direct drive motion system

open access: yesIET Power Electronics, Volume 16, Issue 13, Page 2192-2202, 14 October 2023., 2023
Because of the zero‐transmission structure of the direct drive system, the feedback harmonics caused by the disturbances will be coupled with the detent force and intensify the couplings among different sources of thrust harmonics, which will produce new thrust harmonics, deteriorating the dynamic precision and efficiency of the motion system ...
