This NEMA 23 bipolar stepper motor delivers 125 oz·in of holding torque with 200 steps per revolution (1.8° step angle). Equipped with extra-long 600 mm AWG22 wires, it's designed for CNC applications where longer cable runs are needed.

Stepper motors provide precise position control without the need for an encoder, making them ideal for CNC machines, 3D printers, plotters, and other motion control systems that require accurate, repeatable positioning.

Key Features

  • 125 oz·in Holding Torque – Strong holding force for reliable positioning
  • 200 Steps Per Revolution – 1.8° step angle for fine position control
  • NEMA 23 Form Factor – Standard mounting pattern for CNC and motion systems
  • 600 mm Lead Wires – Extra-long AWG22 wires for CNC installations
  • Bipolar, 2-Phase – Compatible with standard bipolar stepper drivers

Specifications

  • Motor Type – Bipolar, 2-phase
  • Steps Per Revolution – 200
  • Step Angle – 1.8°
  • Voltage – 3.2 V
  • Current – 2.0 A per phase

Resources

Jargon buster

Plain-language definitions for the technical terms used above.

encoder
A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
Torque
A twisting force that causes something to rotate, usually measured in newton-metres or kilogram-centimetres. It matters when choosing motors, servos, gears, and tools because higher torque is needed to lift heavier loads, turn larger wheels, or move mechanisms without stalling.
