    • The invention relates to an electric machine (1), especially a starter for an internal combustion engine, comprising a commutator (4) and a brush apparatus (2), brushes (3) being arranged on the commutator (4) in such a manner that at least one pair of brushes can rotate off-set from each other, every brush (3) being held in a brush holder (5), every brush holder (5) being fastened to an axial face on a brush plate (6), every brush (3) being alternately switchable in series either with a negative pole or a positive pole by a current conducting device (18, 19) to give a pair of brushes, and the brush plate (6) with connecting leads (24, 25, 26) leading to brushes (3) on the negative pole side and a busbar (10) with connecting leads (21, 22, 23) leading to brushes (3) on the positive pole side forming a respective current conducting device (18, 19). In order to protect the brush apparatus (2) from thermal overloads in an easy manner, at least one current conducting device (18, 19) is designed to have a unit for reducing heat dissipation.
    • 将描述一种电机(1),特别是启动器的内燃机中,具有整流子(4)和电刷装置(2),其特征在于,在换向器(4)的刷子(3)与至少一个一对电刷的彼此偏移布置laufbar 其中,在保持器(5)刷每个刷子(3)容纳,每个电刷架(5)在刷板(6)的轴向端部侧固定,每个电刷(3)交替地与任一负的或电流导向装置的正极 (18,19)是可切换的,以串联的一对电刷,电刷板(6)具有连接线(24,25,26)到负极侧刷(3)和一个功率轨(10),连接线(21,22,23),以pluspolseitigen (3)刷每一个都具有流动引导装置(18,19)的形式。 因此,就这么简单靠在刷装置(2)的热过载可能保护被实现,至少一个流动导向装置(18,19)被设计为用于热耗散的减少的装置。
