NEMA 17 Stepper Motor 42-34 1.3A 0.27Nm 42*34mm

The NEMA 17 Stepper Motor (Model B0878, 42-34 series) is a high-precision, high-torque hybrid bipolar stepper motor designed for demanding motion control applications. With a standard 1.8-degree step angle (200 steps per revolution), a rated current of 1.3A, and a holding torque of 0.27 N.m, this motor provides the perfect balance of speed, accuracy, and holding power. It is the go-to choice for 3D printers, CNC engraving machines, laser cutters, and precision robotic arms.

This stepper motor features a 5mm D-shaped shaft that prevents gear or pulley slippage under high loads, ensuring reliable mechanical transmission. It comes equipped with a detachable 1-meter PH-6P to XH2.54 4-pin cable, making it directly compatible with popular controller boards like RAMPS 1.4, CNC Shield, and Creality 3D printer mainboards. It operates seamlessly with standard stepper drivers such as the A4988, DRV8825, and silent TMC2208/TMC2209 series.

Features:

• High Precision: Standard 1.8° step angle (200 steps/rev) for accurate positioning.
• Optimized Torque: Delivers a minimum holding torque of 0.27 N.m, ideal for axis movement and extruders.
• D-Shaped Shaft: 5mm diameter shaft with a flat edge prevents pulley slippage.
• Detachable Cable: Includes a 1-meter high-quality PH-6P to XH2.54 4-pin cable for easy wiring.
• Low Heat & High Efficiency: Low phase resistance of 2.0 Ω and 2.7 mH inductance ensure efficient power delivery.
• Wide Compatibility: Works perfectly with Arduino, Raspberry Pi, ESP32, and standard stepper drivers.
