Embeddable servo motor drives & controls


About Granite Devices


"In 2006 I needed servo drives but I was surrounded by the cumbersome or inflexible choices on the market. I saw it better to build my own." - Tero Kontkanen, co-founder of Granite Devices

We are known from two distinguishable branches

Industrial motor drives branch

The core business of Granite Devices involves development and competence in electric motor drives and controls. The current focus is in miniature servo motor drives, such as IONI. Granite Devices also designs and licenses custom embeddable drives. For instance an e-bike motor drive solution for revolutionary Revonte bikes.

Sim racing equipment branch

Granite Devices' excellence in high-end torque controllers and a strong will to serve their customers has sparked a separate branch for professional sim racers. Granite Devices sim racing products are known as Simucube. Read more at simucube.com.

The whole story

From the very beginning to present day

Granite Devices' 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 55 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.

The Simucube branch

Granite Devices' excellence in smooth and fast torque controllers, as well as open-source friendliness, sparked an widespread demand of Granite Devices motor drives in professional sim racing e-sports community. Circa 2017 ARGON and IONI drives were the most popular choice in force feedback steering wheel open-source and professional OEMs communities.

As Granite Devices spirit heavily leans towards customer service, the first Simucube product was developed in order to aid the sim racing customers. Lear more about Simucube development, see Simucube Tech web site.

As of now, Simucube has grown as separate business branch known not only from force feedback wheels, but also many other related industrial grade devices. Learn more at Simucube.com.
