Measurement Minute: Episode 2

In this episode of Measurement Minute, we'll dive into data for troubleshooting electric drive systems and why it is so challenging.

From Component to Vehicle Energy Management

Why unified data is your best friend in troubleshooting electric drive systems

Electric drive systems are incredible feats of engineering, but they’re also incredibly complex, so when something goes wrong, they can quickly turn into a puzzle. A typical system brings together a motor, an inverter, a gearbox, and a controller – each of which may be designed by different teams or sourced from different suppliers. Getting all of these components to work seamlessly is no small task.

Why troubleshooting is so challenging

When you integrate these parts, unexpected behaviour is almost guaranteed. For example, when you apply a torque step and the response isn’t what you expected. Maybe there’s a resonance between your control algorithm and the machine. Maybe the inverter isn’t behaving as it should. These issues can stall development, making troubleshooting one of the most difficult and time-consuming phases of bringing electric drive systems to market.

The power of unified data

By recording large amounts of data across the system – with a common time step and common filters – engineers gain the clarity they need to pinpoint problems.

With unified data, you can start answering critical questions:

If there’s a vibration, where is it coming from?
If a torque step doesn’t respond as expected, what was happening inside the inverter at that exact moment?

Faster insights, faster to market

A common data acquisition system ties everything together. By measuring the motor, inverter, controller, and mechanical system in sync, engineers can see the bigger picture – and the root causes – much faster.

The result? More effective troubleshooting, reduced delays, and a smoother path to market. In an industry where timing is everything, the ability to diagnose and fix problems quickly is a competitive advantage.
