英语翻译
By using electric power generated by the motor 5 due to an inertia rotation of the rotor 1 as a power source for the high-frequency oscillation circuit for applying a high-frequency voltage to the piezoelectric element 6 at the time of shutdown,
the high-frequency oscillation circuit may be constructed as a simple circuit which functions as a damping device at the same time.
同时,高频振荡电路也许可以用一个可实现减震设备功能的简单电路来完成.
第一句怎么也分不出结构,第二句按照自己的理解翻了,
第一句应该如何入手?
主要是介词太多又分不清楚是起什么作用的,比较难.
as a power....是不是rotor1的定语从句?
转子1的惯性旋转能提供供电机5使用的电力。在电机停止工作时，转子1作为高频振荡器的电源，可以提供高频电压给压电元件。
以上是自己翻译的,如果是这样的话,上面的as a power就是rotor的定语从句了对吗?
