AUTOMATIC DETECTION OF A MECHANICALLY COMMUTATED DC MOTOR

摘要

In order to automatically detect a mechanically commutated DC motor (2), it is provided to acquire an electrical engine size (Ew), to determine current ripples (R) in said engine size (Ew), to evaluate the amplitude (AR), the duration and/or time position of the detected current ripples (R) and to compare to known ripple patterns, and to choose from a known key data table (T) a number of key data assigned to a certain engine type, when the amplitude (AR), duration and/or time position of the detected current ripples (R) correspond to a ripple pattern, which is assigned to said engine type.
