Topic: Confused about how to use a stepper motor (Read 4434 times) previous topic - next topic



I am using the following stepper motor. I have a stepper motor driver which can drive two stepper motors. There are 4 connections for each motor. This stepper motor however has eight wires. Can anyone help me on how to connect my stepper motor to the driver.

Can someone help me with which wires go into which ports and point me in the write direction of how I control the motor with Arudino code.

Use the third configuration (BI-Polar Series).
Doesn't really matter the order, just follow the specs of the stepper.
If for some reason the cables are different color, use a tester to identify the coils.

Based on the specs you are safe...


4 H-Bridges: L293D chipset provides 0.6A per bridge (1.2A peak) with thermal shutdown protection.

So 0.7A will be safe, but make sure to supply extra power to the board (extra 9v could be enough for one stepper).

The Arduino won't be able to run the stepper by itself.
That's where you use the "EXT. POWER" connectors of the driver!
