摘要
介绍了一种应用直流伺服电动机的控制系统中 ,采用电枢控制实现电机调速的实用电路 ,即具有± 2 4 V输出电压的功率放大器。此电路的特点是通过调节已给定电压值 ,就能在放大器的输出端得到足以能驱动电动机转动的较大电压。
Introduces a practical circuit, a power amplifier with ±24V output voltage,This circuit is applied in the DC servo electromotor controlling system, which changes the speed of motor by adjusting the voltage of armature The feature of the circuit is that a higher voltage that drives the motor will be put out at the amplifier by adjusting a given value of voltage The circuit is valuable in practice
