Simple Driver DC Motor Stepper Electronic Schematic using Transistor

Eltronicschool. - One kinds of DC motor is Motor Stepper that have good precision position. To make DC motor stepper move according direction that we want, we must provide driver DC motor stepper circuit schematic. Although there are many DC motor stepper that sold that make from transistor or integrated circuit, we think we also can make by our self circuit of dc motor stepper easily included using transistors component.

In this time we want to share with you one of the Simple Driver DC Motor Stepper Electronic Schematic using Transistor that easily to build. To make this circuit schematic you only need three components this is transistor, diodes, and resistor. Please see figure 1 below.

Circuit Schematic

Component List
  1. Q1 - Q4 : Transistor D400
  2. R1 - R4 : Resistor 1K
  3. D1 - D4 : Diode IN4004


The electronic circuit schematic Simple Driver DC Motor Stepper Driver like in figure 1 above is very simple electronic circuit to drive motor stepper. All of transistor D400 used to electronic switch to on and off motor stepper.   

We can run the stepper motor with give forward bias in input transistor D400. To get good rotation of motor stepper, we can adjust step-by-step all input that usually connected with microcontroller. 

Thank you for your coming here in site, we hope the article above will help you to know more about your an electronic circuit design and software in this time, etc. Please comment here when you want to share and other. Thank you.
