The 17HS2310 is a exceptionally high-torque Nema 17 stepper motor, featuring standard faceplate dimensions of 42.3mm x 42.3mm. While typical Nema 17 motors used in standard desktop 3D printers offer a holding torque around 0.4Nm, the 17HS2310 utilizes a lengthened motor body (Approx 60mm) to deliver a heavy-duty holding torque of 0.75Nm. Drawing a manageable 1.5A per phase, it serves as the ultimate upgrade component for machinery that demands high mechanical holding force without upgrading to larger Nema 23 mounting footprints.

Specifications

• Model Number: 17HS2310
• Frame Size: Nema 17 (42.3mm x 42.3mm)
• Holding Torque: 0.75Nm (Approx 106 oz-in or 7.6 kg-cm)
• Rated Current: 1.5A per phase
• Configuration: 4-Wire Bipolar
• Step Angle: 1.8℃ (200 steps per full revolution)
• Motor Body Length: Approx 60mm (Extended body design)
• Shaft Type: D-Cut (Machined flat edge to prevent pulley slipping)
• Shaft Diameter: Standard 5mm
• Phase Resistance: Low internal resistance for efficient thermal handling

Features

• Extended Frame High Torque: The internal rotor and stator stacks are physically elongated inside the 60mm housing, packing nearly double the holding torque of standard desktop-class Nema 17 motors.
• Excellent Driver Compatibility: At 1.5A, this motor runs perfectly within the peak efficiency window of entry-level and advanced stepper drivers alike, such as the A4988, DRV8825, TMC2208/TMC2209, and TB6600.
• D-Shape Output Shaft: Designed with a flat indentation running down the length of the 5mm drive shaft. This flat surface gives grab screws on timing gears, GT2 pulleys, and lead-screw couplers a rigid anchor point, preventing systemic drift during fast deceleration.
• Industrial Thermal Resilience: Built using Class B insulation materials (130℃ threshold), allowing the motor to run safely under dense operational duty cycles in hot enclosures.

Common Applications

• Desktop CNC Engravers: Powering the X, Y, and Z axes on machines like the Genmitsu CNC where Nema 23 frames won't fit, but high torque is required to push cutting bits through wood and acrylics.
• Heavy-Duty 3D Printers: Operating heavy dual Z-axis leadscrews or driving high-mass direct-drive extruder toolheads without missing steps.
• Medical & Lab Instrumentation: Driving precision syringe pumps, automated sorting turntables, and linear staging gear.
• Automated Camera Sliders: Providing the heavy static torque required to tilt and slide heavy DSLR/Cinema camera rigs up vertical inclines smoothly.

Usage & Tuning Tips

• Calibrate Current Limits (VREF): You must adjust the current limit potentiometer on your stepper driver (e.g., setting the VREF on an A4988 or DRV8825) so it does not exceed the motor's 1.5A rating. Running the driver uncalibrated can pump excessive current into the motor, melting internal coil insulation and frying the stepper driver.
• Never Unplug Under Load: Never disconnect the 4-wire cable from the motor or driver while the system is powered on. Doing so creates a massive inductive back-EMF voltage spike that will immediately destroy the driver's output transistors.
• Microstepping Selection: Setting your driver to 1/4 or 1/8 microstepping yields excellent torque retention and positioning precision. While 1/16 or 1/32 microstepping makes the motor whisper-quiet, note that incremental holding torque drops significantly between microsteps.
• Operating Temperatures: Stepper motors convert excess energy into heat; it is entirely normal for the aluminum body of the 17HS2310 to sit at 50℃ - 65℃ during intensive prints or cuts. If it becomes uncomfortably hot to touch instantly (>75℃), consider lowering your driver current setting down to 1.2A - 1.3A to preserve hardware longevity
