Creality 3D 42-40 léptetőmotor

This bipolar stepper motor delivers precise motion control for Creality 3D printers, with a holding torque of 0.42 N.m and a 1.8° step angle ensuring accurate positioning for extruders and axes. The NEMA 17 frame (42 x 42 mm) and 40 mm body length make it a direct replacement for Ender 3, Ender 5, and CR-10 series machines.

Advantages

Rated at 1.68A per phase with a 2.55V coil voltage, the motor runs cool and efficient. The D-cut 5mm shaft provides secure coupling, while the JST-XH 4-pin connector simplifies installation. Class B insulation and an operating range of -10°C to +50°C ensure reliability in demanding environments.

Suitable for

• Extruder drive on Creality Ender 3, Ender 5, and CR-10 series
• Z-axis lifting and X/Y-axis movement
• Upgrades or repairs requiring a NEMA 17 bipolar stepper with 0.42 N.m torque
• Custom 3D printer builds needing a compact, high-torque motor
