Part 1: What is Torque Ripple and Cogging Torque in Electric Motors

This webinar will be a brief introduction to torque ripple and cogging torque in electric machines. It will cover the sources of torque ripple, the importance of torque ripple, and the needed measurement equipment.

Part 2: Introduction to Noise and Vibration in Electric Motors

This webinar will introduce elements of electric motors and inverters that cause noise and vibration. This webinar will cover the basics of electric machines and how the construction and control contribute towards noise and vibration, plus methods of measurement and visualization of these phenomena.

Part 3: Introduction to Measuring Electric Power During Transients

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. This webinar will explore the need for testing during transients and instrumentation techniques that were not previously available.
