Testing of electric motors: 99% measurement accuracy in powertrains isn't enough!


Modern vehicle development requires the highest level of precision; otherwise, development times are extended and costs rise. Learn more.


In modern vehicle development, the powertrain is no longer purely a mechanical matter. We operate in a world where milliseconds and micrometers determine market success or regulatory compliance.

Whether it’s a highly efficient internal combustion engine, a hybrid, or an electric vehicle: high-precision measurement technology is the invisible enabler behind every innovation.

Why is “good” no longer enough? Here are three reasons:

  1. The quest for efficiency at the limits: With electric motors, fractions of a percent in efficiency determine the range. To understand inverter losses at switching frequencies in the MHz range, we need measurement technology that thinks faster than the system itself.
  2. NVH & customer experience: An electric car is quiet, which makes even the slightest noise (whistling, vibrations) a quality killer. Only through high-frequency vibration analysis in the sub-micrometer range can we achieve the smooth operation that customers demand today.
  3. Digital twins need real-world data: A simulation is only as good as the data it is fed. High-precision test bench data is the gold standard for calibrating digital twins. Without exact measurements, the simulation remains a mere estimate.

Conclusion: Today, measurement technology is no longer merely a tool for troubleshooting. It is a strategic instrument for accelerating development and reducing costs.

Those who cut corners on precision today will pay for it tomorrow in rework —or fall behind in global competition!

Labortechnik Tasler offers exactly the right measurement technology for this: High-precision, flexible, and synchronous measurement data acquisition systems, optimized for test benches. The LTTsmart, in particular, is an ideal power analyzer for testing electric drives.

NEW: Some of our products are now also available through our distribution partner LISAB in Sweden.
