Part 1: Learning Materials

 

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

Recorded Live Session

Download the slides

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 1: Introduction to Noise and Vibration in Electric Motors

Recorded Live Session

Download the slides

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 1: Introduction to Measuring Electric Power During Transients

Recorded Live Session

Download the slides

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.

Part 2: Learning Materials

Part 2: Measuring Torque Ripple in Electric Machines

Recorded Live Session

Download the slides

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, frequency analysis of torque ripple, correlation of electric and mechanical signals, frequency analysis of torque signals and measurement considerations including bandwidth and accuracy.

Part 2: Electric Motor NVH Case Study and Analysis

Recorded Live Session

Download the slides

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

Recorded Live Session

Download the slides

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.
