摘要

In an apparatus for controlling an electric drive motor (22), which is connected to an electronic speed control and / or regulating device, a rotary actuating element is connected to the drive motor (22). In order to control the drive motor (22) so that no damage occurs even under different operating conditions, there is a device (47) for automatically determining the load of the drive motor ( 22) during operation, which is connected to a device (48) for comparison with predetermined values for the load, to which is connected a display device (45) and / or a switching device (49), which can receive electrical signals in the case of deviations.
