Nema 17 Stepper Motor 190mNm High Torque 1.8 Deg Standard Step Angle 1A/3.7V 22.5mm(0.89inch) Bipolar 2 Phase 4 Lead Low Noise for CNC Engraving Machine and Precise 3D Printing
[Size]: Nema 17 Bipolar Stepper Motor: Shaft Diameter: Φ 5mm ( D Shaft Φ 4.5mm ), Shaft Length: 24±0.5mm, 42x42x22.5MM / 1.66x1.66x 0.89inch, 2 phase, 4 wires: Black (A+), Green (A-), Red (B+), Blue (B-).
[Low Power Consumption]: At rest or at low speed, the power consumption of the stepper motor is relatively low, which helps to save energy and reduce emissions.
[Easy Maintenance]: The stepper motor is usually easy to disassemble and assemble, the parts are easy to replace, and the maintenance cost is low.
[Reversibility]: The direction of rotation of the stepper motor can be reversed by changing the order or polarity of the control signal, which has strong flexibility.
