NEMA 17 17HS4401S-22B Stepper Motor

The 17HS4401S-22B NEMA 17 Stepper Motor is a robust, high-torque 2-phase hybrid bipolar stepping motor engineered for precision motion control in desktop 3D printers, CNC routers, and robotic systems. Delivering a holding torque of 43N.cm (approx. 4.3 kg.cm) at a rated current of 1.7A per phase with a 1.8-degree step angle (200 steps/revolution), it ensures smooth positional accuracy, low vibration, and dependable holding strength under mechanical load.

Featuring a standard 42 x 42 mm NEMA 17 mounting profile and a 5 mm D-cut shaft, this motor easily integrates with GT2 timing pulleys, rigid couplers, and lead screws. It is fully compatible with popular stepper drivers such as A4988, DRV8825, and TMC2208/TMC2209 running on Arduino CNC shields, RAMPS 1.4, or ESP32 and STM32 motion controllers. Whether building a custom 3D printer axis, DIY laser engraver, or automated positioning rig, this stepper motor provides reliable plug-and-play performance.

Features:

• High Holding Torque: Provides up to 43N.cm of holding torque for precise, stall-free positioning.
• Standard 1.8-Degree Step Angle: Delivers 200 discrete steps per revolution for high resolution motion.
• Bipolar 4-Wire Configuration: Detachable 4-pin JST connector harness for neat cable routing and easy wiring.
• Standard NEMA 17 Flange: 42mm frame size with standard M3 mounting hole spacing for direct drop-in replacement.
• D-Cut 5mm Drive Shaft: Flat shaft section prevents slippage of timing pulleys and couplings under load.
• Wide Driver Compatibility: Operates seamlessly with A4988, DRV8825, TMC2208, and TMC2209 stepper drivers.
