Quick question: I have a stepper motor that is 0.25 degrees per step, and so 4 steps is required for a degree. When we pump 20 steps into it, it moves 5 degrees. However, if we go to pump another 20 steps into it right after that, it does not move 5 degrees. Is it possible that residual flux is preventing it from fully rotating after the initial rotation?(adsbygoogle = window.adsbygoogle || []).push({});

An example of what will happen is as follows:

pump in 20 steps: get 5 degrees of rotation

pump in 20 steps: get 2 degrees of rotation

pump in 20 steps: get 5 degrees of rotation

pump in 20 steps: get 2 degrees of rotation

and so on

.....

It seems to be consistent in that sense. Any clarification or insight would be appreciated.
