控制信号由接收机的通道进入信号调制芯片，获得直流偏置电压。它内部有一个基准电路，产生周期为20ms，宽度为1.5ms的基准信号，将获得的直流偏置电压与电位器的电压比较，获得电压差输出。最后，电压差的正负输出到电机驱动芯片决定电机的正反转。当电机转速一定时，通过级联减速齿轮带动电位器旋转，使得电压差为0，电机停止转动。当然我们可以不用去了解它的具体工作原理，知道它的控制原理就够了。就象我们使用晶体管一样，知道可以拿它来做开关管或放大管就行了，至于管内的电子具体怎么流动是可以完全不用去考虑的。-Control signal from the receiver into the signal modulation of the channel chip, access to the DC bias voltage. It has a base internal circuit, resulting in a period of 20ms, the base width of 1.5ms signal, will be the DC bias voltage and the voltage comparator potentiometer to obtain the output voltage difference. Finally, the positive and negative output voltage difference to the motor driver chip motor positive decision. When the motor speed must, through the reduction gear drive cascading rotary potentiometers, the voltage difference is 0, motor to stop rotating. Of course, we do not have to understand the principle of its work, the control principle to know its enough. As we use the same transistors that can switch it to do or to enlarge
