What the steps/rev are for this stepper motor?
please see the below formula:
E-Steps-per-MM=(Motor Steps * Micro-stepping*Gear Ratio) / (Hobb Diameter*π)
Standard motor steps / rev =200
Standard micro-stepping = 16x
Gear Ratio = 3
Hobb Diameter (Effective)= 7.3
Warning:
Make sure the motor connect to a constant current or chopper drive controller before you test motor.
Connecting the motor directly to a power supply will destroy the motor.
