Improve stepping motor step accuracy
Improve stepping motor step accuracy
(OP)
I'm designing in a stepping motor in optical disc drive. The step accuracy is poor. Microstepping is adopted. Step accuracy improves, but still not good enough. Any idea how to improve the step size? I'm not considering of reduction in leadscrew pitch size.

Are you sure that the inaccuracies aren't coming from the lead screw?
Could look at direct-drive & sevo systems too.

He makes small angle steppers and can help with details of inertia.
