Stepper Motor 42HS32 NEMA17 MAX. 0.32 N.M

Overview

The Stepper Motor 42HS32 NEMA17 is a compact and reliable bipolar stepper motor, ideal for a wide range of DIY electronics projects, 3D printers, CNC machines, and robotics. With a 1.8° step angle (200 steps per revolution) and a holding torque of 3.2 kg·cm (0.32 N·m), it offers precise positioning and smooth motion control. Its 4-wire design simplifies wiring, making it a favorite among makers and engineers in Egypt.

Key Features

• Precision Control: 200 steps per revolution with 1.8° step angle for accurate positioning.
• Torque: Holding torque of 3.2 kg·cm (0.32 N·m) per phase, providing ample power for lightweight applications.
• Bipolar Design: 4-wire bipolar configuration for efficient torque and speed.
• Compact Size: Standard NEMA17 (42mm square) body, easy to mount in various projects.
• Rated Voltage: 12V rated, but can be driven at lower voltages (torque will decrease accordingly).
• Durable Construction: 35 ohms per winding, with 12-inch leads for flexible wiring.

Technical Specifications

• Rated Voltage: 12V DC
• Max Current: 1.0 A per phase
• Resistance: 35 ohms per winding
• Wiring: 4-wire bipolar, 12-inch (approx. 30cm) leads
• Body Size: 42mm x 42mm (NEMA17)
• Mounting: 31mm square mounting holes, compatible with M3 screws
• Weight: Approx. 280g (typical for this size)

Applications & Use Cases

• 3D Printers: Extruder and axis motors
• CNC Machines: Small engraving and milling machines
• Robotics: Joint actuation and precise positioning
• Automation: Conveyor belts, indexing tables, and camera sliders
• Education: Ideal for university projects and STEM learning

What's Included

• 1x Stepper Motor 42HS32 (NEMA17)
• (Note: Mounting screws and driver are not included)

Compatibility

• Drivers: Works with common stepper drivers such as A4988, DRV8825, TMC2208, and others that support bipolar stepper motors.
• Controllers: Arduino, Raspberry Pi, ESP32, and other microcontrollers with appropriate driver circuits.
• Power Supply: Use a 12V supply for full torque; lower voltages (e.g., 5V) will still work but with reduced torque.
