Abstract (en)
[origin: EP1092867A2] The control circuit (5) for an electric starting motor, at an internal combustion motor, is structured to determine the heating and/or the load on the starting motor, at least at one point of the motor (1), from the voltage waves in the main current circuit of the starter motor current (I). The threshold value transmitter (10) gives the set max. loading on the electric starter motor (1). A comparator uses the motor loading and the threshold value to generate a signal if the threshold value is breached upwards or downwards. On receipt of the signal, a cut-out (20) restricts the force flow to the IC motor (6), and cuts the current flow to the starter motor (1). The control circuit (5) registers the current (I) to the armature of the start motor (1) and the temp. of the motor carbon brushes.
