Drive Technology from 16g to 100 kW
Our systems are engineered for environments where failure is not an option. Every component is tested beyond standard duty cycles.
Up to 100 kW
Power Range
Embedded motor controllers up to 80 kW and brake chopper modules up to 100 kW. Available as open frame on request.
12 - 999 V
Input Voltage Range
From 12V battery systems to 999V DC link. The logic unit is identical; we adapt the power electronics to your requirements.
Up to 100,000 rpm
Motor Control with FOC
Precise and efficient control even at high speeds for spindles, turbines, and high-speed actuators.
From 16g
Brake Chopper
The lightest brake chopper starts at 16g. Designed for UAVs and other weight-critical platforms.
Why customers develop their drives with us
Your controller does not simply get discontinued.
We build your specific servo controller from a component repertoire we have proven many times over. The controller can be manufactured by your own EMS assembler.
Your special case gets programmed in.
One customer needed the actual position from an external encoder while commutation kept running off the motor encoder. With a bought-in drive that would have become a workaround. Here it goes into the control model in the firmware.
Drive, brake chopper and safety from one team.
Whatever brakes feeds energy back — that has to be part of the sizing. With us the concept, the controller and the brake chopper come from the same team, instead of three supply chains blaming each other when voltage spikes in the DC link destroy sensitive electronics.
You talk to the engineers.
No ticket system. We are a small company, so you simply reach the people who are working on your project with you.
Got an idea or a project? Let's get started.
One hour, free of charge, by video or at our place in Zurich. We look at where the technical risks are, what can be shortened and what the next sensible step would be. No pitch, no slide deck. You leave with more clarity than you arrived with — even if we never work together.
