Large Hollow Low Voltage Driver

Built with modular architecture, this large‑hollow low‑voltage driver applies model predictive vector control algorithm. It integrates on‑board STO and SBC via 24V I/O and is manufactured by Infranor in France.

Introduce

Next-Generation Low-Voltage Motion Control for Integrated Robot Joints

Designed to empower modern collaborative and humanoid robots, the Large Hollow Low Voltage Driver seamlessly integrates advanced motion control algorithms with a space-saving hollow-shaft design. Manufactured by Infranor in France, it utilizes Model Predictive Vector Control algorithms to achieve exceptional dynamic response, torque stability, and whisper-quiet operation under 48V low-voltage supply. Featuring integrated functional safety functions (STO & SBC based on 24V I/O) and modular adaptability, this driver sets a new benchmark for high-density, safety-critical robot joint control.

Features

Precision, Intelligence, and Modular Power Combined  

Designed for maximum thermal and spatial efficiency, our low-voltage hollow drivers seamlessly bring together high-performance vector control, built-in safety, and effortless joint integration.  

  • Modular & Hollow Structural Design

    Features a large hollow-shaft architecture that allows convenient internal cable routing, enabling a clean layout and ultra-compact integration into robot joints. 

  • Model Predictive Vector Control Algorithm

    Employs advanced model predictive control to ensure high dynamic response, smooth torque delivery, and minimal speed ripple during complex movement.  

  • Integrated On-Board Safety Functions (STO & SBC) 

    Built-in Safe Torque Off (STO) and Safe Brake Control (SBC) based on 24V I/O provide robust hardware-level safety compliance without extra cost or complexity. 

Applications
