NEMA 17 Stepper Motor 42BYGH 38mm 1.3A 0.28Nm 42*38mm

The NEMA 17 Stepper Motor (42-38 series) is a high-precision, high-torque bipolar motor designed specifically for 3D printers, CNC routers, and laser engravers. Operating at a rated current of 1.3A DC per phase and a rated voltage of 2.86V DC, this motor delivers a minimum holding torque of 0.28 N.m (28 N.cm). Its compact 38mm body height makes it an ideal choice for space-constrained builds without sacrificing performance or positioning accuracy.

This 2-phase stepper motor features a standard 5mm D-cut shaft to prevent pulley slippage under high loads. It is fully compatible with popular stepper drivers like the A4988, DRV8825, and TMC2208/TMC2209, making it easy to integrate with Arduino, RAMPS 1.4, or ESP32-based control boards. The package comes complete with a 1-meter long connection cable featuring a PH-6P connector on the motor side and a standard 2.54mm pitch connector on the controller side for quick, plug-and-play installation.

Features:

• High Torque Output: Delivers a minimum holding torque of 0.28 N.m for precise and reliable motion control.
• Standard NEMA 17 Form Factor: 42.3mm x 42.3mm faceplate with a compact 38mm body length.
• Optimized Electrical Specs: Rated at 1.3A per phase with a low phase resistance of 2.2 ohms and 4.2 mH inductance.
• D-Cut Shaft: Features a 5mm diameter D-shaft (23mm total length) to ensure secure pulley mounting.
• Class B Insulation: Built with high-quality materials rated for Class B insulation, ensuring long-term reliability.
• Included Cable: Comes with a 1-meter high-quality connection cable (6-pin PH-6P to 4-pin 2.54mm connector).

Package Includes:

1 x NEMA 17 Stepper Motor (42-38 Series)
