Product Description The NEMA 17 Hybrid Stepper Motor is the gold standard for precision motion control in desktop 3D printers, small CNC machines, and robotic actuators. Delivering a reliable 3.5kg-cm of holding torque, this motor utilizes a hybrid design to combine high resolution with significant power. Its standardized 42mm frame size and 1.8-degree step angle allow for ultra-precise positioning, ensuring that your 3D prints are smooth and your robotic movements are repeatable.

Key Features

  • High-precision 1.8° step angle (200 steps per revolution).

  • High torque output of 3.5kg-cm, ideal for X, Y, and Z-axis movement.

  • D-shaped 5mm shaft for secure mounting of pulleys and couplers.

  • Low vibration and quiet operation when paired with microstepping drivers.

  • Durable metal construction with high-quality bearings for long-term use.

Technical Details

  • Step Angle Accuracy: +/- 5% (full step, no load)

  • Temperature Rise: 80°C Max

  • Ambient Temperature Range: -20°C to +50°C

  • Insulation Resistance: 100MΩ Min. 500VDC

  • Dielectric Strength: 500VAC for one minute

  • Phase: 2 Phase (4-wire)

  • Inductance: Approx. 3.8 mH per phase

  • Motor Length: Approx. 38mm to 40mm (excluding shaft)

Prototyping and Engineering Tips from Robogears

  • Driver Pairing: To get the best performance, use a dedicated stepper driver like the A4988, DRV8825, or TMC2209. These drivers allow for "Microstepping," which breaks down the 1.8° step into much smaller increments for smoother motion.

  • Current Tuning: Always adjust the Vref (Voltage Reference) on your stepper driver to match the motor's rated current (approx. 1.2A). Over-driving the motor will cause it to get extremely hot and potentially skip steps.

  • Wiring Check: Identify your phases (A+, A-, B+, B-) using a multimeter. If the motor "vibrates" but doesn't spin, two of your wires are likely swapped.

  • Heat Dissipation: Stepper motors are designed to run warm, but if the motor body is too hot to touch, consider adding a 42mm heatsink or reducing the current from the driver.

Package Includes

  • 1 x NEMA 17 Hybrid Stepper Motor (3.5kg-cm)
