Embodiment Construction

[0010] figure 1 The starting device is shown in longitudinal section. exist figure 1 The starting device 10 is shown in . The starter device 10 has, for example, a starter motor 13 and a switching relay 16 . Both starter motor 13 and switching relay 16 are fastened in a common drive end bearing housing 19 . The starter motor 13 is functionally available to drive the starter pinion 22 when the starter pinion 22 meshes in a ring gear 25 of the internal combustion engine (not shown here).

[0011] The starter motor 13 as a drive motor of the starter has a pole tube 28 as a housing, which has a plurality of pole shoes 31 each wound by a field winding 34 on its inner periphery. The pole shoe 31 in turn surrounds an armature 37 , ie a rotor 38 , which has an armature core 43 consisting of laminations 40 and an armature or rotor winding 49 arranged in slots 46 . The armature core 43 is pressed against the drive shaft 44 . Also mounted on the end of the drive shaft 44 remote fro...

Abstract

An electrical drive machine having a stator (35) and a rotor (38), wherein said rotor (38) carries a rotor winding (49) in grooves (46), which can be supplied with electrical current via a power supply system made of a commutator (52) and sliding contacts (58), wherein said sliding contacts (58), which press on a surface of said commutator (52), have at least two pairs made of one positive sliding contact (581) and one negative sliding contact (582) each, wherein said positive sliding contact (581) and said negative sliding contact (582) oppose one another at an angle which deviates by 180 DEG in at least a first pair of one positive sliding contact (581) and one negative sliding contact (582).

Description

technical field [0001] The invention relates to a drive motor (electric motor for a starter) having a stator and a rotor, wherein the rotor can be supplied with current via a commutator and sliding contacts (brushes). Background technique [0002] Such motors are widely used. In this case, the current for operating the drive motor is introduced into the rotor winding (armature winding) via one or more pairs of sliding contacts via a commutator. These sliding contacts are mostly made of sintered materials mainly containing graphite components. These sliding contacts and the commutator are subject to wear during operation. Starting devices are usually designed for short-time operation and are usually suitable for 30,000 to 60,000 switching cycles, that is, the starting process. [0003] If higher loads and greater switching cycles are to be achieved, the slider must have an even load so that the maximum possible switching cycles can be achieved. At present, for systems wit...
