Our Mission

"Empowering our customers to complete their tests in record time with exceptional performance."​

Engineered for

Who can benefit from our system

Developers of electric machines

For in-depth analysis of machines on the test bench.

Test engineers

For component, function, or system validation.

Application engineers

For determining operating data, performance, and thermal behavior of unknown machines.

Software developers

For quick testing of self-developed functions in real environments.

What makes us different

Key Benefits

Fast commissioning

Typical machines are fully operational within two days including sufficient torque accuracy, peak power, and torque dynamic.

Easy to use

User-friendly operating concept offers a “one-click” solution for commissioning, characterization, and evaluation of electric machines.

Highly Adoptable

Be ready for every machine type, angle sensor and test environment that might occur in the future. Our software offers a wide range of configurations to be prepared for all test scenarios.

High Performance

With switching frequencies up to 20 kHz, a maximum DC link voltage range from 48 V to 1000 V and currents up to 1000 Arms your test system is ready for future challenges.

Easy Integration

The system can be integrated in existing testbed system. Your testbed automation and predefined test scenarios can be used as before. No limitation to individual testbed manufacturers.
