Abstract:
A starting motor for an internal combustion engine, having gearing to the engine, the gearing producing a closed linkage between the starting motor and the engine, during a starting operation of the engine, the starting motor having a battery, the starting motor comprising:a control circuit for measuring at least one of a starter voltage and a starter current that causes a crankshaft of the internal combustion engine to be driven, the control circuit determining at least one of the starter current, a temperature rise and a load at at least one point of the starting motor as a function of a voltage ripple in a primary circuit of the starting motor; a comparator for presetting a maximum load of the starting motor; a Schmitt trigger for emitting a signal from load values and a predefined limiting value, in response to the limiting value being one of exceeded and undershot; and a safety device for limiting an induction flux to the engine, in response to an appearance of the signal.
