Abstract

A starting motor for an internal combustion engine, where a control circuit monitors or controls the temperature of the starting motor or the carbon brushes, and if necessary, limits or switches off the primary current. The temperature is indirectly determined by means of a comparison, using the voltage ripple in the primary circuit between the battery and the starting motor. Occurring errors can be stored as status messages in an error storage device, and if desired, they can be interrogated and corrected at the next service interval.
