Answer: A stepper motor which is turned by a load produces a back EMF voltage on the driver. Better speeds will make better voltage degrees. When the rotational velocity will get excessively large, this voltage might harm the driver. This is especially dangerous If your motor is back again-driven although https://worktopwhizyxu.bloginder.com/40645459/a-guide-to-the-maintenance-of-a-stepper-motor
