Stepper Motor Controller Wiring Diagram

This circuit can be used with a wide range of operating voltages from approximately 5 v to 18 v.

Stepper motor controller wiring diagram.

This circuit is a general purpose stepper motor controller that use ic tda2030 as the driver. The next diagram shows the connections for an 8 wire parallel connected bipolar stepper. Since coils a and b on the diagram above are not connected the resistance between leads a1 and b1 or between a1 and b2 will be infinite. Each component should be set and connected with different parts in particular manner.

In the case of the buildbotics cnc controller the maximum current is 6 amps for any individual motor port. If your stepper motor has 4 wires it is a bipolar stepper motor. A uln2003 darlington transistor array ic1 switches current through the stepper motor s two windings in either direction. If not the structure won t function as it should be.

It could be expanded to allow for the control of multiple motors with four of the maximite s external i o pins used to control each motor with identical driver circuits. There are many version of stepper motor type also the many version of stepper motor controller design.

The following diagram shows the connections to be made for an 8 wire series connected bipolar stepper motor.
