The 17HS1910-P4170 is a high-torque Nema 17 stepper motor featuring standard faceplate dimensions of 42.3mm x 42.3mm. Utilizing a medium-extended motor body length (Approx 48mm), it strikes an excellent balance between mechanical holding force and physical mass. Delivering a holding torque of 0.55Nm while drawing a standard 1.7A per phase, this motor is a staple high-performance component for performance-driven 3D printers, desktop CNC machines, and custom automation equipment.

Specifications

• Model Number: 17HS1910-P4170
• Frame Size: Nema 17 (42.3mm X 42.3mm)
• Holding Torque: 0.55Nm (Approx 78 oz-in or 5.6kg-cm)
• Rated Current: 1.7A per phase
• Configuration: 4-Wire Bipolar
• Step Angle: 1.8℃ (200 steps per full revolution)
• Motor Body Length: Approx 48mm
• Shaft Type: D-Cut (Flat surface to prevent pulley or gear slippage)
• Shaft Diameter: Standard 5mm
• Phase Resistance: Low internal resistance (designed for high-speed current chopping)

Features

• High Torque Performance: Offering 0.55Nm provides a significant power upgrade over stock 0.4Nm motors, preventing skipped steps during high-acceleration moves on 3D printer axes or heavy direct-drive setups.
• Standard Industrial Rating: The 1.7A phase current rating is the industry standard for high-performance Nema 17 execution. It maximizes the power delivery capabilities of popular stepper drivers like the A4988, DRV8825, TMC2208, and TMC2209.
• D-Shape Output Shaft: Machine-cut flat flat edge ensures that timing pulleys, GT2 gears, or rigid couplers lock down with maximum mechanical grip, eliminating positional errors caused by loose grab screws.
• Dynamic Speed Curve: Optimized for constant-current chopping, allowing the motor to maintain high torque retention even as rotational speeds (RPM) increase.

Common Applications

• 3D Printer Axis Control: Powering heavy Y-axis beds or driving quick X-axis toolhead carriages on large Cartesian or CoreXY printers.
• Desktop CNC Routers: Operating the linear travel stages on hobby machines (like the 3018 CNC) cutting wood, plastics, and engraving brass or aluminum.
• Precision Extruder Systems: Running gear-reduced direct-drive extruders (like the BMG or Titan) that require dense torque to push filament uniformly.
• Automated Factory Sorters: Controlling mechanical pushers, timing belts, and indexing conveyor mechanisms.

Usage & Tuning Tips

• VREF Calibration is Critical: Do not plug this motor into an uncalibrated driver. Check the current limit potentiometer (VREF) on your stepper driver and set it so that the output current matches or slightly sits below the 1.7A rating. Running too much current will trigger rapid motor overheating, while too little current will cause low torque and missed steps.
• Never Disconnect While Powered: Never unplug the 4-wire motor connector from your control board while the power supply is actively turned on. Disconnecting a stepper motor under load induces a massive high-voltage back-EMF spike that will instantly destroy the stepper driver's transistors.
• Thermal Management Expectation: Stepper motors convert excess current into heat; it is completely normal for the aluminum body of this motor to reach temperatures up to 50℃ - 65℃ during intensive operation. However, if the motor body exceeds 80℃ (too hot to touch for even a split second), dial down your driver's operating current slightly to protect the lifespan of the internal magnetic core.
