Description
The 42-40 Stepper Motor is a high-torque NEMA 17 motor engineered specifically for the demands of high-speed CoreXY printing. Unlike standard stepper motors, this unit is built to withstand the high internal chamber temperatures of the K1 and K1C without losing magnetic flux or "missing steps."
It features a precision-ground shaft and high-quality internal bearings to ensure smooth motion and minimal vibration, which is essential for achieving the clean surface finishes the K1 series is known for. This is the factory-direct replacement, ensuring perfect electrical compatibility with the Creality mainboard without the need for rewiring or firmware current adjustments.
Features
High Torque Density: Provides the necessary power to move the K1's gantry at accelerations up to 20000mm/s without overheating.
Heat-Resistant Design: Rated for high-temperature environments, making it ideal for the enclosed chambers of the K1 and K1C.
Low Noise & Vibration: Precision-balanced rotor reduces "motor whine" and mechanical resonance, contributing to quieter operation.
Plug-and-Play: Features the standard 6-pin JST-PH connector used on the K1 series wiring harness for a fast, tool-free electrical connection.
Durable Aviation Aluminum: The motor body is constructed from high-grade aluminum for improved heat dissipation.
