时栅位移传感器的动态特性研究
Study on Dynamic Performance of Time Grating Displacement Sensor
摘要
Abstract
In order to solve the dynamic measuring problem of time grating angular displacement sensor,through introducing motion unit module,a dynamic electromagnetic simulation model was es-tablished based on the static state electromagnetic simulation of time grating displacement sensor.The relationship among amplitude,frequency of the induced electromotive force and the speed of the rotor as well as magnetic field distribution was analyzed when time grating displacement sensor functions under its dynamic conditions.It is also predicted that the maximum speed is approximately 8 r/min theoretically when the time grating displacement sensor is running with 400 Hz excitation frequency. The experimental results show that the error of the time grating displacement sensor is as ±1 .4″un-der the speed of 0~8 r/min and when the rotary speed of the time grating displacement sensor exceeds 8 r/min,the error of the time grating displacement sensor begins to deteriorate.The error of the time grating displacement sensor is as ±8.2″at the speed of 10 r/min.关键词
