Omni Series UTO Frameless Torque Motor | Direct Drive Motor
The Omni Series UTO frameless torque motor delivers high-performance direct drive motion in a compact, low-profile design with an outside rotating configuration. Engineered for OEM applications, it provides high torque density, smooth operation, and exceptional design flexibility for robotics, automation, and precision motion control systems.
Its large through-hole design allows engineers to route cables, pneumatic lines, optics, or other system components directly through the motor. As a result, the Omni Series UTO simplifies mechanical integration while helping reduce the overall size and weight of the system.
Designed for dynamic motion, the motor combines high mechanical stiffness with low rotor inertia, enabling fast acceleration, precise positioning, and responsive axis control. In addition, its low cogging design minimizes torque ripple, ensuring smooth, accurate motion across the entire operating range.
To support a wide variety of applications, the Omni Series UTO is available with custom windings and form factors. Furthermore, it integrates easily with many industry-standard servo controllers and drives, allowing OEMs to optimize performance for their specific system requirements.
