Abstract:
This paper provides more details of dynamic behaviors of the feed drive system which consists of an AC servo motor and rolling elements etc. In the feed drive system, the nonlinear behaviors of the internal structure of the rolling element have an crucial influences on precise control performance. Our special interest is how to verify the fundamental data of dynamic behaviors of the feed drive system in the vicinity of a microscopic displacement. Experimental data show that the driving torque curve becomes distorted as the input amplitude of sinusoidal wave to the system gets larger, but the curve forms are independent of the input frequencies.
