NEMA 17 Stepper Motor 42x40mm 1.5A 0.40Nm for 3D Printer

The NEMA 17 Stepper Motor (Model A0022) is a high-precision, high-torque hybrid bipolar stepper motor designed specifically for 3D printers, CNC routers, and laser engravers. Featuring a standard 42mm x 42mm faceplate and a compact 40mm body length, this motor delivers a robust holding torque of 0.40 N.m. It operates at a step angle of 1.8 degrees (200 steps per revolution), ensuring exceptionally smooth and accurate positioning for detailed printing and engraving tasks.

This stepper motor is fully compatible with popular stepper driver modules such as the A4988, DRV8825, and TMC2208/TMC2209 silent drivers. It comes equipped with a 5mm D-shaped shaft to prevent gear or pulley slippage under load, and includes a detachable 1-meter cable with an XH2.54 connector for easy integration with RAMPS, MKS, or Creality 3D printer mainboards. Whether you are building a custom CoreXY 3D printer, a mini CNC machine, or upgrading your existing setup, this motor provides the reliability and performance required by makers and engineers alike.

Features:

• High Holding Torque: Delivers a minimum of 0.40 N.m, perfect for maintaining precise positioning under load.
• Standard NEMA 17 Form Factor: 42.3mm x 42.3mm frame with a 40mm body height fits standard mounting brackets.
• D-Shaped Drive Shaft: 5mm diameter shaft with a flat D-cut ensures secure pulley and gear mounting without slippage.
• Detachable Cable Design: Features an onboard PH-6P connector and includes a 1-meter XH2.54 4-pin cable for flexible wiring.
• Optimized Electrical Parameters: Rated at 1.5A per phase with a low 2.0 Ohm phase resistance for efficient, cool operation.
• High Resolution: 1.8-degree step angle provides 200 physical steps per full rotation for high-precision motion control.

Package Includes:

1 x NEMA 17 Stepper Motor (42x40mm)
