Next-Generation Direct-Drive Power System Solution for Robot Vacuums-Direct Drive Tech

Next-Generation Direct-Drive Power System Solution for Robot Vacuums

Benmo Technology provides integrated direct-drive power solutions to manufacturers of complete robot vacuum units. Centered on proprietary direct-drive technology that eliminates the need for a gearbox, the solution features a highly reliable permanent magnet synchronous motor that integrates an outer-rotor brushless motor, an encoder, and a servo drive. It offers advantages such as a compact structure, ease of installation, stable operation, a small footprint, and high torque.

Pain points of traditional solutions

The traditional drive and reduction solution for robot vacuums—combining a high-speed, compact motor with a gear reduction train to amplify torque through gear meshing—remains the industry standard; however, it suffers from inherent structural limitations that cannot be fully resolved through tuning alone.

Direct Drive Tech: Empowering Product Upgrades with Direct-Drive Technology

Moving away from traditional motor-gearbox architectures, the company utilizes a deeply integrated system comprising an outer-rotor direct-drive motor, a high-precision encoder, and a servo drive. Featuring a gearless transmission design and fully in-house development, the technology is backed by a comprehensive patent portfolio. Benmo Technology’s direct-drive power modules have successfully passed rigorous validation by leading consumer robotics brands and have been delivered at a scale of millions of units, providing high-performance solutions for core components in robot vacuums.

We deliver multi-dimensional industry value through direct-drive power modules.

It delivers a quiet, durable cleaning experience that reshapes user perception, while also helping OEMs create differentiated selling points, build a competitive moat, and shorten R&D cycles—providing a new generation of domestically produced drive bases for AI cleaning robots.
