Dual Shaft NEMA 23 Stepper Motor 2A – High-Torque Hybrid Motor for CNC Routers & Heavy 3D Printers

Overview

The Dual Shaft NEMA 23 Stepper Motor (2A variant) is a high-torque, hybrid bipolar stepping motor designed for demanding mechanical applications. Featuring a standard 57mm x 57mm faceplate, this motor delivers the substantial holding torque required to move heavy gantry axes on CNC milling machines without skipping steps. The unique dual-shaft setup offers maximum versatility, allowing you to drive your load from the front while easily attaching position tracking encoders, dampeners, or manual tuning knobs to the back.

Key Features

• Dual Shaft Versatility: Rear shaft extension allows for manual handwheels, rotary encoders, or fail-safe electronic brakes.

• High Torque Density: Engineered to handle high axial and radial loads, preventing axis sagging or stalling during heavy cutting passes.

• Low Heat Generation: Optimized 2.0A current rating ensures high torque output while keeping operating temperatures manageable during long production cycles.

• Precision Stepping: Standard 1.8° step angle (200 steps per revolution) provides smooth, accurate microstepping when paired with modern drivers.

Technical Specifications

Common Applications

• DIY CNC Routers & Mills: Driving heavy X, Y, and Z lead screws or rack-and-pinion systems.

• Industrial 3D Printers: Perfect for moving heavy direct-drive extruder gantries or massive heated print beds.

• Laser Engravers & Cutters: Provides precision positioning for high-speed laser heads over large work areas.
