Accelerate PMSM Characterization with Real-Time Stator Flux Linkage Mapping

Learn how HBK calculates stator flux linkage directly from measured signals and automatically generate flux maps on the test bench, enabling faster machine characterization, improved model accuracy and deeper insight into motor behavior.
 

The Challenge

Characterizing modern electric machines takes time.

Accurate stator flux linkage data is essential for validating motor control strategies, creating reliable machine models, understanding saturation effects and optimizing torque production. However, obtaining this information can be time-consuming and computationally demanding.
 

Engineers often face challenges such as:

• Extracting accurate fundamental signal components from inverter measurements
• Maintaining measurement accuracy as operating temperatures change
• Identifying saturation and cross-coupling effects across large operating ranges
• Generating comprehensive flux maps quickly enough to support development timelines

The Solution

Automated flux mapping in real time

In this webinar, our expert Dr. Alexander Stock presents an efficient methodology for calculating stator flux linkage in real time using measured electrical and mechanical quantities.

By combining direct coordinate transformation with intelligent averaging techniques, engineers can generate accurate flux maps without relying on computationally intensive Fourier analysis.

You will also learn two complementary approaches for ensuring reliable results during real-world testing:

• Temperature-compensated stator resistance calculations
• Flux determination based on mechanical air-gap power
