Abstract
A method for detecting commutation pulses of a fan motor with continuous measurement and storage of voltage values that are proportional to the fan current within predetermined time intervals. The measured voltage values are continuously evaluated by comparing two measured values that were obtained at different times. A result signal is outputted if the deviation between the compared measured values fulfills a predetermined constraint.
