Measuring torque ripple and cogging torque in electric machines

Torque ripple and cogging torque are disturbances in torque that have a frequency and amplitude proportional to speed. Torque ripple can cause problems with durability, noise, vibration and motor control. To minimize torque ripple, engineers need to measure and understand what the frequency and amplitude of this torque ripple are. This session will introduce torque ripple and how to measure it.
