Packing List: 5pcs Nema 17 Stepper Motor 42x23(17HS4023), 5pcs 39.3in(1Meter) Cable
High Torgue: German tech bearings, low self-inductive reactance, good responsivenes, longer life and low working temperature.
Low Noise: The internal rotor of stepper motor adopts German tech. And the surface is coated with imported rotor glue to prevent the burr on the surface caused by the oxidative grinding of carbon steel that cause the motor noise.
Low Resistance: SIMAX3D Stepper motor gets low resistanse, thus enables good thermal conductivity. It will work at a safe temperature.
2 Phase, 1.8 Degrees, Compatible with all FDM 3D printer that need 42x23mm extruder motor.
