Abstract

In order to automatically detect a mechanically commutated DC motor, it is provided to acquire an electrical engine size, to determine current ripples in the engine size, to evaluate the amplitude, the duration and/or time position of the detected current ripples and to compare to known ripple patterns, and to choose from a known key data table a number of key data assigned to a certain engine type, when the amplitude, during and/or time position of the detected current ripples correspond to a ripple pattern, which is assigned to the engine type.
