What is a NEMA 17 Stepper Motor?

A NEMA 17 Stepper Motor is a stepper motor with a 43.18×43.18mm (1.7 x 1.7 inch) face plate. This NEMA 17 is larger and generally heavier than for example a NEMA 14, but this also means it has more room to put a higher torque.

Nema 17 stepper motor specifications

  • Step Angle: 1.8°
  • Rated current (single phase): 1.7 A
  • DC Rated Voltage: 3.06 V
  • Winding dc resistance (25 C): 1.8 Ω ± 10%
