Hello, First time posting. I wanted to check if the DRV8825 stepper motor driver should be able to work with this 1.5A/coil Nema17 stepper motor.
I’ve already tested a pair of these together and the driver seemed to make the motor step, although the driver and motor both got hot pretty quickly, even when I was only holding the motor at a constant position and not stepping. Unfortunately, I seemed to have damaged either the motor or driver on a second test since the motor won’t step anymore, and just makes a loud squeal. Although, I can still hear the motor trying to step when I send pulses to the step pin.
I feel like this setup should work since the driver has a 1.5A/coil current output, and therefore shouldn’t provide more than the motor’s current limit,1.5A as well, and if anything the current limiting potentiometer can be used to prevent over-current to the motor. On the other hand, I’m worried that the motor may have tried to pull more current than the driver can supply and fried the driver instead, unless my understanding of how stepper motors and drivers work is incorrect.
I’ve also looked at the driver data-sheet, but am kind of confused about the max current through individual coils vs the total current vector magnitude through both coils.
Any recommendations on how to determine which, motor or driver, is broken? or whether I should even be using these two together? Thanks!
