Embodiment Construction

[0032] FIG. 1 shows a schematic circuit diagram of a circuit arrangement 1 together with an electric machine 2 . The circuit arrangement 1 together with the electric machine 2 forms a starter device 17 for starting the internal combustion engine 15 . This electric machine is the starter motor 2 for this purpose. The circuit arrangement 1 comprises a series resistor 3 as a current limiting device and a device 4 bridging the series resistor 3 . The bridge device 4 is a switching device, which is preferably designed as a relay due to the very high currents. The circuit arrangement 1 comprises two relays, namely a first switching device 5 and a second switching device 7 . The first switching device 5 is actuated via a switch 6 . The switch 6 is, for example, an ignition key switch or an electronic switch connected to a start button, or a switch activated or deactivated by a start-stop control. The first switching device 5 closes the switching contact 51 in order to apply volta...

Abstract

The invention relates to a circuit arrangement (1) for an electrical machine (2), in particular for a starter motor (2) for starting an internal combustion engine (15) in a motor vehicle, comprising a current limiting device (3) for limiting the cut-in current of the electrical machine (2). To prevent a voltage drop in the most reliable manner possible during the start operation of an internal combustion engine, a bridging device (4) for bridging the current limiting device (3) is provided and the bridging device (4) can be directly connected to a high potential of a voltage source (10).

Description

technical field [0001] The invention relates to a circuit arrangement for an electric machine, in particular a starter motor for starting an internal combustion engine in a motor vehicle, having a current limiting device for limiting the inrush current of the electric machine. The invention also relates to a method for operating, in particular, a circuit arrangement as described above for an electric machine, in particular a starter motor for starting an internal combustion engine of a motor vehicle, said circuit arrangement having a current limiting for limiting the inrush current of the electric machine device. Furthermore, the invention relates to a starter device for starting an internal combustion engine in a motor vehicle, having the circuit arrangement described above, a starter motor and a current limiting device for limiting the inrush current of the electric machine. Background technique [0002] Starting devices with a starter motor for starting an internal combu...
