Purpose: Our objective is to develop an entirely new the feed drive system with the accuracy of tens nanometers and the stroke of tens millimetres achieved by only one mechanism. Design/methodology/approach: The dynamic driving torques can be measured when the sinusoidal waves of the microscopic displacement are applied to the AC servo motor. The mathematical model of the feed drive system that considers this dynamic behaviour is proposed. Findings: We make hysteresis phenomenon clear in the range from 2 μm to 100 μm by the nonlinear spring characteristics. Taking the friction model into account, the driving torque can be formulated. The proposed friction model represents successfully the experimental results for the sinusoidal wave within the ranges of amplitude from 2 μm to 100 μm. In case that the amplitude is 1 μm, though the amplitudes of the driving torque are slightly different, the curve shows the similar shape. Research limitations/implications: The results of this research covers the feed drive system with the AC servo motor and rolling guide. But, because the dynamic behaviour the rolling element was analyzed, it can be also applicable to the feed drive system with rolling element. Practical implications: This paper presents more details of driving torque in microscopic motion area, so that the performance of the feed drive system with rolling elements can be improved. Originality/value: The originality of this research project is to develop an entirely new feed drive system with the one mechanism and with the high accuracy.
