Reducing Cogging, Transient Torque, Torque Ripple
Measuring torque is essential for different kind of tests and applications. Especially in electric-machine testing, it is important to understand the effiency 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. But what happens exactly during the measurement and how can cogging torque, torque ripple and other characteristics be measured and reduced?
