Stepper Motor Inductance

  • Stepper motors can come in different inductances and resistances.
  • Resistance determines the current. Low current can be run with RAMPS - up to 2A with cooling


What does inductance determine? See Stepper Motor. Lower the inductance, the better the performance at high speed, as coils can respond fast. Makes sense.


  • Check out the low rated voltage here - [1]. Does this mean that the stepper driver controls voltage to get the right current? What is the max power supply voltage of this stepper motor?
