    Abstract: A method for monitoring a belt drive with a power-transmitting endless drive belt which is in the form of a traction belt and wraps around the drive and driven pulleys circumferentially over a partial circumference in each case, wherein the belt has at least one first marking and a first sensor element assigned to the belt is provided and is used to detect the passage of the first marking during the belt revolution, wherein the first sensor element has devices for outputting a signal SR dependent on the detection of the first marking, wherein the rotor of the drive motor has a second marking and a second sensor element which is provided with corresponding electronic devices and is assigned to the drive motor is provided, wherein, while the rotor is rotating, the passage of the second marking is detected by the second sensor element and a signal SM dependent on the detection of the second marking is output, wherein, furthermore, a computing unit provided with memories and processors for processing the signals SR and SM is provided, wherein a temporal or local correlation of the occurrence of the signals SR and SM is calculated in the computing unit when the drive belt is new and is stored as a reference value, and the associated signals SR and SM are then repeatedly determined for further specified belt revolutions or periods of time and their current temporal or local correlation of the occurrence is compared with the reference value.
