摘要:
The invention relates to an electric machine, in particular a commutator machine (10), the carbon brushes (14) of which cooperate with a commutator (13) to supply the rotor with current, the carbon brushes (14) being continuously provided or provided in layer sections with different additives such as scouring material, lubricants or similar. To achieve a longer service life for the carbon brushes (14), a maximum of half, preferably less than half of all the carbon brushes (14) of the machine have a significant fraction of an additive, said fraction differing from that of the other carbon brushes (14).
摘要:
A circuit configuration for an electric machine, e.g., a starter motor for starting an internal combustion engine in a motor vehicle, includes a current limiting device for limiting a starting current of the electric machine. The circuit configuration includes a bridging device for bridging the current limiting device.

The invention relates to a starting device (22) for internal combustion engines (10). The starting device (22) comprises an electric drive (28) for a drive pinion (24). A gearwheel (16) is mounted on the crankshaft (12) of the internal combustion engine (10). An engaged state of the drive pinion (24) on a drive shaft (26) of the electric drive (28) is effected either by a spacer piece (40) or the starting device (22) is arranged with a reduced spacing (54) in relation to the gearwheel (16).

摘要:
A carbon brush system for an electrical machine, having at least two carbon brushes, which are situated axially adjacent to one another and cooperate with a rotatable countercontact system. The carbon brushes are implemented as directly or indirectly mutually axially supporting carbon brushes.

A device for starting an internal combustion engine of a motor vehicle includes a starter motor having an actuator for engaging a pinion, drivable by the starter motor, with a ring gear, and a control unit which activates a switching output stage associated with the actuator and a switching output stage associated with the starter motor. The starting time of the internal combustion engine is substantially reduced by providing the starter device with a control unit.

The invention relates to a starter device (10) for internal combustion engines (15) in motor vehicles with a controller (19), a starter relay (12), a starter pinion (13) and a starter motor (11), whereby on each start/stop process in the stop phase (first step) the starter relay engages the starter pinion in the toothed ring (14) of the engine and in the start phase (second step) the engine is turned over by the starter motor. According to the invention, the starter pinion (13) may be engaged as quietly as possible for a subsequent starting process on switching off the engine (10) and held in position until starting, whereby, in the first step of the starting process, the armature (28) of the starter relay (12) is withdrawn with reduced force to a position with open switch contact (18) and held there until the start of the second step, whereupon the armature (28) closes the switch contact (18) of the starter motor with full force.
