The Dedicated Drive Specialists

For many years, general-purpose, cabinet-mounted “bookshelf” drives were the industry standard. More than a decade ago, however, OJ Electronics concluded that OEMs would benefit from a different approach: Dedicated drives designed specifically for the applications they serve.

Today, our purpose-built drives are integrated into systems around the world, supporting ventilation, cooling and heating, and heat recovery applications in factories, agricultural facilities, data centers, airports, and many other environments where reliable and efficient operation is critical.

Regardless of application, our customers benefit from a state-of-the-art drive platform that combines advanced technologies, compact design, rugged construction, and compliance with the industry’s most demanding standards and regulations.

A Powerful Platform

At the core of every OJ drive is a modern technology platform designed to deliver high performance, energy efficiency, and reliability across a wide range of applications.

Advanced motor control technologies such as sensorless field-oriented control (FOC) ensure precise operation and optimal efficiency, while our slim DC-link architecture enables compact designs and simplified integration. Together, these technologies help OEMs create high-performance solutions with a smaller footprint and lower system complexity.

The platform is available with both passive and active front-end technology, allowing drives to be optimized for different application requirements. Advanced thermal management, robust component design, and variants capable of operating in temperatures from -40 °C to +70 °C help ensure reliable operation, reduced sensitivity to thermal cycling, and a long service life. The electronics are protected by a rugged, high-IP-rated metal housing designed for demanding environments.

Finally, our decentralized approach places drive intelligence where it creates the most value. By locating drives in direct proximity to fans, rotors and compressors, OEMs can reduce installation complexity, create more compact solutions, and integrate drive functionality directly into their own systems.
