【Abstract】 D. C. motor has been widely used as tracting part in intelligent instrument measurement. However, as limited by the structure of D. C. motor it self, the control circuit for D. C. motor is usually complex. Based on experimental results, a novel displace measurement system which applies the grating sensors has been designed by the authors. This system has the features of simple structure, low cost and high reliability.更多还原
