rotational coupling meaning in English

转动耦合

In the second chapter , equivalent circuit of the eddy current sensor is firstly analyzed . based on that , the carrier signal generating circuit that is realized by the lc periodic circuit is introduced , thus , the carrier signal of standard frequency is obtained through the trimming capacity . subsequently , the disc type rotational armature generator and the rotational coupling transformer are separately leaded in to realize the power supplies of the carrier signal generating circuit and output of the measuring signal
在传感器设计一章中，首先对涡流传感器进行等效电路分析，在此基础上分析了由电感、电容谐振电路构成的载波信号发生电路，并通过微调电容获得了标准频率的载波信号；接下来提出了采用盘式旋转电枢发电机解决载波信号发生电路电源供给问题的方案，同时通过旋转耦合变压器的引入，使得测量信号输出问题很好地解决；本章最后给出的一组实验曲线充分说明了这一方案的可实现性。
