Designing a unipolar stepper driver using STM32 MCU, lack of torque
I am working on my first robotics project which will hopefully become a desktop sized KUKA iiwa. Unfortunately, I have only just completed the first year of my electrical engineering degree so have ...

Need help figuring out how to organise a system to run a stepper motor at low speed without Steps-skipping
TL;DR : How to prevent step-skipping with a NEMA gearbox motor at low speed.
Edit: following @glen_geek comment, removing the load on the system seems to remove the problem, hinting at inertia and ...

Stepper motors both rated for higher current but the NEMA 23 stops and the NEMA 17 keeps going, could it be a (hardware) low quality motor issue?
I am using the DRV8825 stepper motor driver. The NEMA 17 is rated for 1.2 A and the NEMA 23 I'm using says it's rated for 2A. I have two NEMA 23s and they both soon choke out (stop moving).
When I was ...

Why are stepper motor phase currents a sinusoildal waveform?
I don't know if this is a really dumb question or not, but I've seen all kinds of torque, peak-current and RMS discussions related to current drive output for stepper motors. I acknowledge that for a ...

Run Stepper motor with more torque and smoothly
I have a stepper motor and its torque curve is below.
I am trying to get more torque from the motor. Therefore, I decided to setup my driver to half step. I am using an Arduino for generate the ...

How does this part of the schematic control the torque?
This is a part of the schematic for a chinese built TB6600 stepper driver. The TQ pin (torque setting) can be either LOW when the torque is reduced to 30% or HIGH when its 100%. How does this part of ...
