Description:
The Creality 42-40 Stepper Motor is a high-torque NEMA 17 motor engineered specifically for the demanding precision of the Z-axis. On the Ender-3 V3 KE, this motor is responsible for driving the lead screw to position the X-axis gantry with sub-micron accuracy.
As a genuine OEM part, it features the exact electrical characteristics and physical dimensions required to interface perfectly with the printer's Z-axis coupler. The motor is built for durability and low heat generation, ensuring consistent layer heights and preventing "Z-wobble" or layer shifts during long, complex prints.
Features:
High-Torque Performance: Provides a holding torque of 0.4 Nm, essential for lifting the weight of the X-axis gantry and toolhead without skipping steps.
Precision Stepping: Features a standard 1.8 step angle (200 steps/revolution) for fine-tuned vertical resolution and smooth motion.
Silent & Smooth Operation: Optimized internal construction reduces resonance and vibration, contributing to the quiet operation characteristic of modern Creality machines.
Effective Heat Dissipation: Designed to operate at high duty cycles while maintaining low thermal output, protecting the motor's lifespan and the surrounding plastic mounts.
Plug-and-Play: Includes the standard 6-pin connector interface for immediate installation without soldering or wiring modifications.
