STEPPERONLINE Nema 23 1.8deg 3.0Nm

Product Description :

The Nema 23 Stepper Motor 23HE45-4204S is a high-torque, heavy-duty motor designed for CNC machines, 3D printers, milling machines, robotics, and automation systems. With a holding torque of 3.0Nm (425 oz-in) and a 1.8° step angle, it provides powerful, precise, and stable motion control even under demanding loads.

Built with hybrid stepper motor technology, the 23HE45-4204S operates as a bipolar stepper with 2 phases and a rated current of 4.2A per phase. Its low phase resistance (0.9Ω) and inductance of 3.8mH allow for efficient operation and high-speed performance.

The motor features a 57 × 57mm Nema 23 frame size, a 113mm body length, and a 10mm D-cut shaft (24mm length, 20mm flat) for secure coupling. The 500mm leads (4-wire) make integration easy, while the insulation class B (130°C) ensures safe operation and long lifespan.

Weighing 1.8kg, this robust stepper motor is ideal for heavy-duty CNC and industrial applications where torque and precision are critical.
