Overview
The CMI 17EP070-1652 stepper motor planetary gearbox is a compact, integrated motion control solution for industrial automation, robotics, and precision equipment. This assembly pairs a NEMA 17-class stepper motor with a sealed planetary gearhead, delivering high holding torque and precise positioning in applications requiring low speed and high force output. The design eliminates the need for external coupling or separate gearbox installation, reducing assembly time and simplifying system integration.
Key Features
- Integrated NEMA 17-class stepper motor with planetary gearbox—no external coupling required
- High reduction ratio for significant torque amplification and holding strength
- Sealed, low-backlash planetary design for accurate, repeatable position control
- Compact form factor suitable for space-constrained automation systems
- Bipolar stepper motor with standard step angles for easy driver integration
- Industrial-grade construction for reliable operation in manufacturing and control applications
Technical Specifications
The exact electrical and mechanical specifications for the CMI 17EP070-1652 and 4118L-25SD-06 should be verified against the official CMI datasheet or your system integrator before installation. Standard NEMA 17 stepper motors typically operate at nominal voltages between 2–5 V, with phase currents of 1.5–2.0 A. Gearbox reduction ratios commonly range from 3:1 to 100:1 depending on the specific model variant. Contact your supplier or CMI directly for detailed motor holding torque, output torque, backlash, inertia, and thermal ratings.
