About us and what we do


HDD was founded in 1994 by Lennart Stridsberg. He was optimizing machines he had developed for MyData Automation and found that the existing servo motors on the market were not good enough. So he invented new ones. Better ones.

Some 20 years later, HDD still has the most compact electric motors on the market. Our patented Stritorque® technology enables the development of motors with less than half the size of motors with equivalent performance. This fact make them suitable for many applications.

We have a stong technical department and also offer contract services. For information in Swedish please visit: www.tolerans-engineering.se
