Servo Motor Driver Circuit using IC MC33030

Eltronicschool. - When we want to control our servo motor for our robot or other, we need circuit that can work for controller. In here we need servo motor driver circuit that functioned for controlling the servo motor with a DC voltage source and working methods or close loop system in controlling the servo motor.

In here we will give you one schematic circuit for Servo Motor Driver that using IC MC33030 that maybe it is very easy find in electronic component market in your country. MC33030 IC is a special IC chip for servo motor driver with the following features as follow:

  1. The maximum current load capacity (servo) 1 ampere 
  2. Voltage for reference input can be programmed 
  3. Over Voltage Over current shutdown shutdown 
  4. Working with close loop system

Circuit Schematic

Figure 1. Servo Motor Driver Circuit using IC MC33030 (skemarangkaianpcb)

Component List
  1. C1,C2,C5,C7 = 0.1uF 
  2. C3 = 22nF 
  3. C4 = 10nF 
  4. C6 = 10uF/50V 
  5. D1 = LED 
  6. R1,R2,R3,R4 = 4.7K 
  7. R5 = 15K 
  8. R6 = 330 
  9. U1 = MC33030


Circuit schematic like in figure 1 above is Servo Motor Driver Circuit using IC MC33030. According blog of skemarangkaianpcb describe that servo motor driver circuit with IC MC33030 above have 2 position control and feedback control. F POT serves to regulate or control the system feedback or closed loop feedback system servo motor driver. 

While the R POT is used to adjust the position of the servo motor movement. Working voltage servo motor driver circuit using IC MC33030 is 12 volts according to the working voltage servo motors are primarily used. 

The maximum current that can be controlled using a servo motor driver circuit MC33030 IC is 1 ampere maximum. Therefore, it should not be used to control the servo motor with a current consumption of more than 1A, as this may damage the IC MC33030
