Product Description

The 4*9*4 Stepper Motor, also known as the 4x9x4 Micro Motor or High-Torque 4-9-4 Motor, is a compact yet powerful motor designed for precision motion control. It features a robust 4-phase design with dual 9mm shaft extensions, supporting direct integration with gearboxes, encoders, or modular drive systems. Operating within a wide voltage range of 5-24V DC and a temperature tolerance of -20°C to +85°C, it delivers reliable performance in industrial automation, robotics, CNC machinery, and medical equipment. With a peak torque of 0.8 N·m, this motor excels in low-speed, high-precision applications. Its miniature 40mm cubic footprint and shielded construction minimize electromagnetic interference, though its compact size limits passive cooling efficiency. Compatible with standard STEP/DIR control interfaces, it enables seamless communication via RS-485 or CAN protocols for synchronized multi-axis operations.
