Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.

AVR单片机内部AD变换 AVR内部ADC转换原理： AVR单片机内部的ADC转换为10位逐次逼近型ADC。ADC与一个8通道的模拟多路复用器连接，能对来自端口A 的8 路单端输入模拟电压进行采样。单端电压输入以0V (GND) 为基准。器件还支持16 路差分电压输入组合。
