Abstract

A cranking device for internal combustion engines includes a permanently excited cranking motor and an electrical run-down brake, having a switching device (25) which, during the run-down phase of the cranking device, connects the connecting leads of the brushes (4, 4') of the cranking motor (1) to one another via a resistor (24). An additional winding of the engaging relay (15) of the cranking device is used as the resistor.
