WebJan 8, 2024 · The cogging torque is a magneto-static effect caused by the change in magnetic attractiveness and repulsiveness surrounding the rotor magnets during the rotation of the rotor itself. This torque causes ripple and noise hence, it must be reduced especially at small loads and low speeds.
