NEMA 17 Stepper Motor 42x38mm 1.3A 0.28Nm for 3D Printer

The NEMA 17 Stepper Motor (42x38mm) is a high-precision, high-torque electromagnetic actuator designed specifically for demanding motion control applications. With a standard 1.8-degree step angle (200 steps per revolution), this motor delivers exceptional positioning accuracy and reliability. It is engineered to provide a minimum holding torque of 0.28 N.m, making it an ideal choice for the axis drives of 3D printers, desktop CNC routers, and precision laser engravers.

This motor features a standard 42mm square faceplate (NEMA 17 standard) and a compact 38mm body length, allowing it to fit seamlessly into tight mechanical assemblies. It operates at a rated current of 1.3A per phase, ensuring optimal thermal performance and high efficiency when paired with popular stepper drivers such as the A4988, DRV8825, or silent TMC2208/TMC2209 series. The motor is equipped with a 5mm D-cut shaft to prevent pulley slippage and an onboard 6-pin PH-6P connector for clean, reliable wiring interfaces.

Features:

• High Torque Output: Delivers a minimum holding torque of 0.28 N.m for reliable holding and driving capacity.
• Precise Motion Control: Standard 1.8° step angle ensures accurate positioning for high-resolution 3D printing and engraving.
• D-Type Output Shaft: The 5mm diameter shaft features a flat D-cut profile to ensure secure mounting of timing pulleys and couplers.
• Standard NEMA 17 Form Factor: Easily mounts to standard 31mm spacing brackets and plates.
• Class B Insulation: Built with high-quality materials rated for Class B insulation, ensuring stable operation under continuous duty cycles.
• Integrated PH-6P Connector: Features a robust 6-pin JST-PH compatible terminal on the motor body for easy plug-and-play connectivity.

Package Includes:

1 x NEMA 17 Stepper Motor (42x38mm, Black Cover, Without Wiring)
