Starter motor

The starter has the job of rotating the crankshaft of the internal combustion engine at the minimum speed that is necessary for starting up (starting speed).

The starter that is used is coordinated with the engine of the respective vehicle model. The output can be up to 3000 Watts depending on the model.

The starter motor must do more in conjunction with the automatic engine start-stop. The starter motor is therefore configured for a significantly higher number (approximately 8 times) of starting operations. The components of the starter motor have been adapted to the higher requirements.
