Part 2: Measuring Torque Ripple in Electric Machines


Tuesday, September 01, 2020 at 13.00 pm (Berlin Time)

In this session, we are providing a brief introduction to the effects and analysis of torque ripple in electric machines. We will cover the measurement of torque ripple, torque ripple examples, and frequency analysis of torque ripple

  • Correlation of electric and mechanical signals
  • Frequency analysis of torque signals
  • Measurement considerations including bandwidth and accuracy

Part 2: Electric Motor NVH Case Study and Analysis


Wednesday, September 02, 2020 at 13.00 pm (Berlin Time)

This webinar will expand on the previous webinar on noise and vibration in electric machines by showing a case study. By combining tests and creating a common language for testing between powertrain and NVH engineers will be able to be more productive and reduce time to market. This webinar will cover combined testing examples, combined analysis, and test configurations for NVH and powertrain testing in electric motors

Part 2: Transient Power Testing Implementation and Examples


Thursday, September 03, 2020 at 13.00 pm (Berlin Time)

Electric motors have traditionally been used for industrial applications at a fixed speed (50/60hz) and instrumentation reflected that. Now that machines are being used for traction applications with variable speeds in cars, aircraft, and other applications, there is a need to understand how these machines perform in transients. Together, we will discuss the need for testing during transients and instrumentation techniques that were not previously available.

  • Why Transient testing is needed
  • Difficulty of testing transients
  • Drive cycle examples
  • Correct instrumentation for transient testing
