Hello everybody. I am very new to electronics, but am working on a project that involves a stepper motor. I need very precise and smooth control over the motor, at very low rotation rates. I currently have it setup, and working well, using the A3977. This works well within a certain frequency rang…

I struggle to understand how you can fail to drive a motor at such a low speed - the A3977 should make it really simple. What is failing?
