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.
One team from concept to commissioning.
The people who take down your requirements also develop the electronics and firmware, and stand next to you at the machine during commissioning.
Tell us what you have in mind.
An idea in your head? Or still unsure which technical route is the right one? Together we work out which architecture, which components and which timeline suit your plans, and what the next step looks like.
