Story of passion

The story begins from the enthusiastic hobby project of our co-founder, Kontkanen Tero, M.Sc. (Tech.). Kontkanen had a project to build a seriously performing CNC mill/router. By chance, he came by a set of very nice AC servo motors but lacked suitable servo drives. After realizing that the affordable and available choices were too limited, or simply unsuitable for the enthusiastic project, Kontkanen continued digging deeper to the inner workings of a servo motor. After a while he realized that a fully competent AC servo control was attainable with just a handful of the newest electric components by the help of sophisticated real-time algorithms.

This idea led to a year long project to accomplish a simple yet fully capable AC servo motor drive with state of the art high bandwidth field oriented control (FOC). As the project gained plenty of followers living in the same situation, and as it would have been pity to keep it all by him self, he started producing the drives available to anyone in the world at a fair price.

Since one of base philosophies of founder's work was to make things rock solid reliable, and flawless in operation, the name Granite Devices was chosen. The basis for all doing was the focus on robustness and essentials without needing wasteful designs.

So far the chosen path has been proven fruitful, and Granite Devices has gained a solid global follower & customer base. Granite Devices' creations are being used in over 40 countries spread over all continents.

As of today, the original founders of Granite Devices are still personally in charge of inspiring the creation of enthusiastic designs and thriving to exceed customer's expectations.
