摘要
在分析时栅位移传感器的一般信号模型的基础上,深入探讨了三相、两相时栅位移传感器的测量机理,进而提出了一种新型位移传感器——两相非等节距时栅位移传感器,然后详细介绍了它的结构和原理.通过和其它两种传感器的对比表明,该传感器可以在不增加加工难度的情况下,增加传感器的极对数.最后通过实验表明,该传感器的精度比其它两种传感器得到了提高.
On the basis of analyzing general signal modes of time grating displacement sensors, the measuring mechanism of three-phase and two-phase time grating displacement sensors are explored. Then a new displacement sensor, i.e. a two-phase unequal-pitch displacement sensor, is proposed and its structure and theory are introduced. A comparison with other two types of sensor shows that its pole-pair number has increased while its processing difficulty has not been increased. Finally, experiments show that the precision of this sensor is higher than the other two types of sensor.
