Magnetic Field Testing in Seconds – For Greater Efficiency and Quality
Anyone developing or assembling electric motors knows: Magnetic imbalances and NVH irregularities can become costly if detected too late.
We provide the solution: Our test benches analyze the magnetic field of rotors and stators within seconds – cycle-time optimized, fully automated, and with 100% output control.
Whether it’s design validation, prototyping, or quality assurance – our systems integrate seamlessly into any production environment and help identify anomalies early on while optimizing processes.
Failure analysis: In addition to graphical and mathematical analysis, we are able to draw conclusions about the cause from the captured signature – thus offering you a decisive advantage for your process and procurement optimization.
Together with you, we identify potential sources of failure in your product and determine the relevant disturbances in the production environment. We then simulate and analyze the failure pattern and develop a concept for the sustainable elimination of the cause of the failure.

Software and Analysis
Evaluation of the data
Our continuously growing expertise, along with increasing testing and analysis requirements, drives innovation within our existing product portfolio. All of our systems are designed to accommodate future adaptations and can be modified as needed.
3D Magnetic Field Analysis
We measure the magnetic field of your rotor across its entire circumference, creating a magnetic landscape. This map-like representation allows precise localization of any anomalies.
Single Pole Analysis
To further enhance the level of detail and evaluation capabilities of our magnetic field analysis, we now offer the option to isolate and examine individual poles of the rotor—without interference from neighboring poles. This enables previously unattainable methods of rotor quality assessment.
Rotor Segment Analysis
The cross-sectional view allows a comparative analysis of rotor segments, providing valuable insights into magnetization quality.
Skew Angle Detection
The more complex the magnetic configuration, the more difficult it becomes to determine the skew angles afterward. Especially with purchased components, this can be a critical factor. We measure the magnetic skew angle.
Magnetic Field FFT
As root cause analysis has become one of our key features, we now offer the option of order/NVH analysis of the magnetic field. In the event of a manufacturing defect, magnetic imbalance in the rotor can occur, leading to vibration anomalies, performance losses, and increased wear.
