The 17HS1352-P4130 is a compact, pancake-style Nema 17 stepper motor featuring standard faceplate dimensions of 42.3mm x 42.3mm. Utilizing a significantly shortened body length (Approx 34mm), it is engineered primarily for weight-sensitive and space-constrained applications. Delivering a holding torque of 0.28Nm while drawing a standard 1.33A per phase, this motor provides quick acceleration and minimizes mechanical inertia, making it a favorite for compact 3D printer extruders and lightweight robotics.

Specifications

• Model Number: 17HS1352-P4130
• Frame Size: Nema 17 (42.3mm x 42.3mm)
• Holding Torque: 0.28Nm (Approx 40 oz-in or 2.8kg-cm)
• Rated Current: 1.33A per phase
• Configuration: 4-Wire Bipolar
• Step Angle: 1.8℃ (200 steps per full revolution)
• Motor Body Length: Approx 34mm (Short/Pancake profile)
• Shaft Type: D-Cut (Flat surface to prevent pulley or gear slippage)
• Shaft Diameter: Standard 5mm
• Phase Resistance: Low internal resistance (optimized for high-speed current chopping)

Features

• Ultra-Low Inertia: The slim rotor assembly reduces moving mass, allowing the motor to accelerate, decelerate, and change directions almost instantaneously without losing step accuracy.
• Optimized Weight Profile: Minimizes the overall weight of mobile gantries. When mounted directly on a 3D printer toolhead, it drastically cuts down on toolhead weight, reducing ringing and ghosting artifacts at high print speeds.
• D-Shape Output Shaft: Machine-cut flat edge ensures that drive gears, timing pulleys, or rigid couplers lock down with maximum mechanical grip, eliminating positional errors caused by loose grab screws.
• Excellent Driver Matching: At 1.33A, this motor runs beautifully with standard stepper drivers like the A4988, DRV8825, and silent TMC modules (TMC2208/TMC2209) without overstressing control electronics.

Common Applications

• Direct-Drive Extruders: Powering compact, lightweight direct-drive filament mechanisms (such as the Orbiter, Sherpa Mini, or Titan) on high-speed desktop 3D printers.
• Portable Medical Automation: Operating micro-fluidic dosing pumps, laboratory autosamplers, and compact scanning equipment.
• Handheld Gimbal Stabilizers: Providing precise orientation corrections on automated camera rigs where keeping motor weight low is vital.
• Miniature Laser Scribes: Driving the X and Y axes on small-scale desktop laser engraving tools.

Usage & Tuning Tips

• VREF Calibration is Critical: Check the current limit potentiometer (VREF) on your stepper driver and set it so that the output current matches or sits slightly below the 1.33A 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: Due to their smaller physical volume, pancake motors have less surface area to dissipate heat compared to standard-sized motors. It is completely normal for this motor to feel hot to the touch (Approx 55℃ - 65℃) under normal operation. If it exceeds 75℃, lower your driver current slightly to preserve hardware longevity.
