Abstract

In this paper a new novel time-grating displacement sensor of mix-motivating type with the mechanism movement and the traveling wave magnetic field is proposed for the first time. In the research of time-grating displacement sensor, the mechanism-motivating modulation sensor are compared with the electricity-motivating modulation sensor rom various fields. It is found that, on the one hand, the two set of designing thoughts are the same from their essence, their mathematics model are also the same, and they are expressed by the same traveling wave formula; On the other hand, there exists the difference of obtaining the moving coordinate. The former is dependent on the rotary machine equipment, and the later is dependent on the rotary magnetic field. In terms of the two type of motivation, two types of time-grating sensor are developed, that is, the mechanism time-grating sensor and the field time-grating sensor. In the development of two types of time-grating sensor, the presented time-grating sensor of mix-motivating type is firstly developed which is based on the advantage and disadvantage of two types of time-grating sensor as mentioned above. Various experiments are carried out on the time-grating sensor of mix-motivating type, compared with the mechanism time-grating sensor and the field time-grating sensor. The experimental results show that the precision of time-grating sensor of mix-motivating type is improved markedly in comparison with the other two types of time-grating sensor.
