Product Description

The 42HS34-0406 NEMA 17 Stepper Motor is a specialized "Round Type" variant of the standard NEMA 17 frame. While most NEMA 17 motors are square-bodied, this cylindrical design is engineered for applications where radial space is a constraint or where the motor needs to fit into circular bores and housings. Despite its unique shape, it maintains the standard NEMA 17 mounting hole pattern. At Robogears, we recommend this motor for lightweight precision tasks, such as camera sliders, laboratory instruments, and small-scale CNC prototypes in your Pimpri workshop. With a 1.8° step angle, it provides the granular control needed for high-accuracy positioning without the bulk of high-torque motors.

Detailed Key Features

  • Compact Round Body: The cylindrical profile allows for easier integration into tube-based structures and sleek robotic arm designs.

  • 1.8° High-Resolution Steps: Provides 200 discrete steps per revolution, which can be further refined using microstepping drivers for ultra-smooth motion.

  • Low Current Draw: Rated at 0.4A, this motor runs cool and is compatible with entry-level stepper drivers like the L298N or A4988.

  • Precision D-Shaft: Features a 5mm diameter shaft with a flat "D" cut to prevent pulley or gear slippage during high-acceleration movements.

  • NEMA 17 Mounting Standard: Retains the standard $31\text{mm}$ hole-to-hole spacing, ensuring it fits into existing NEMA 17 brackets and mounts.

All Technical Details

  • Motor Type: Bipolar Stepper (4-Wire configuration).

  • Insulation Class: Class B ($130^\circ\text{C}$), ensuring reliability during continuous operation.

  • Phase Inductance: Optimized for stable performance at low-to-medium speeds.

  • Detent Torque: Low internal magnetic friction, allowing for manual positioning when de-energized.

Prototyping & Engineering Tips (Robogears Exclusive)

  • Driver Selection: For the best performance at your Pimpri facility, pair this motor with an A4988 or DRV8825 stepper driver. Since this motor has a low current rating (0.4A), ensure you adjust the driver's Vref (potentiometer) correctly to avoid overheating the motor coils.

  • Mounting Clearance: Because the body is round, standard square-body NEMA 17 dampers may not fit perfectly. Use flat aluminum mounting plates to ensure proper heat dissipation from the motor face.

  • Microstepping: To eliminate "stepping noise" and resonance, enable 1/16 or 1/32 microstepping on your controller. This is especially useful for camera gimbals where vibration must be zero.

  • Wiring Check: Always verify the phase pairs ($A+/A-$ and $B+/B-$) using a multimeter. Connecting a phase wire to the wrong driver terminal can cause the motor to vibrate without rotating.
