The Correlation of Torque Ripple, Cogging Torque, and Transient Torque with Electrical Parameters & More

Measuring torque is essential for different kinds of tests and applications. Especially in electric-machine testing, it is important to understand the efficiency and dynamics. However, torque is not a static value: therefore, measuring torque with a high accuracy is crucial. A high-bandwidth torque measurement is also needed to understand what happens instantaneously. This could be:

• Cogging torque for a steady-state operation
• Torque response during loading
• Torque during control changes

What happens exactly during the measurement and how can cogging torque, torque ripple and other characteristics be measured and reduced? You will find the answers in the following videos and white paper.
