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.
