Creality Sermoon D3 42-27 Stepper Motor 3D ZUBEHOER

This bipolar stepper motor delivers precise axis motion for the Creality Sermoon D3 3D printer. With a 1.8° step angle and 0.45 Nm holding torque, it ensures accurate positioning for X, Y, Z, and extruder drives. The NEMA 17 frame (42mm x 42mm) and D-cut 5mm shaft provide reliable mechanical integration, while the JST-XH 4-pin connector simplifies wiring.

Advantages

Engineered for consistent performance, this motor features a rated current of 1.7 A per phase and low rotor inertia of 68 g·cm², enabling smooth acceleration and deceleration. Its Class B insulation and robust construction support long-term operation in demanding printing environments. The 4-lead bipolar configuration offers straightforward control with standard stepper drivers.
