2 Stepper motor

         electronic driver schematics

 Here are another three examples for electronic stepper motor driver.

These circuits are built  from standard components and can easily be adapted to be controlled by a computer.

 

      Two-Coil Excitation - Each successive pair of adjacent coils is energized in turn.

 

 

 

A variant of above circuit....

      Single-Coil Excitation - Each successive coil is energized in turn.

 

 

 

In this variant I used some ordinary components, available in large number in my "micro workshop" 

       Single-Coil Excitation - Each successive coil is energized in turn.

 

 

All variants was tested and I found only very small and insignificant differences in results.
