A method is provided for generating a compensation variable to compensate for synchronism fluctuations of a motor, including the following steps: recording sensor data by a sensor unit in a first cycle time, transmitting the recorded sensor data in the first cycle time to a motor controller, transmitting the sensor data from the motor controller to a controller in a second cycle time, and processing the sensor data by the controller in the second cycle time. The controller is configured to approximate a compensation variable from the sensor data for a compensation interval, for transmitting the processed sensor data from the controller to the motor controller in the second cycle time, and for evaluating the processed sensor data to provide the compensation value from the motor controller in the first cycle time, based on current sensor data for which the compensation value can be determined in the first cycle time.
