Door panel screws (commonly 8mm, 10mm, T30, or phillips) Glass cleaner. For this experiment, we need a multimeter (a device for measuring electrical resistance). The driver is correctly sized for the motor, any phase current settings are correct (presumably a simple driver always uses max), the loading of the motor doesn't exceed the torque calculated by phase current (up to the max capable by that motor). Dod you know wht voltage the motor is designed for. Thisnway you can measure BEMF, number of steps per revolution, maybe even torque constant- if you use some load on the phases. Browse other questions tagged, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site.
