Helbling used innovative technology to design a motor control board for brushless direct current motors (BLDC motors) for Faulhaber, a traditional family business. Faulhaber’s high-tech miniature and micro drive technology can be found in automated production equipment and robotics, the aerospace industry, optical systems as well as medical and laboratory technology.
The motor control board needed to be designed within a short space of time, since Faulhaber was in urgent need of a release sample. The technical hurdles were high. One of these was to ensure compliance with the demanding EMC requirements of EN 61000. Another was to find a solution for the printed circuit board’s high current density in an extremely small space and with very limited cooling options. Helbling not only boasts a diverse range of skills and the latest know-how in the area of motor controls, but also has its own EMC lab.
