Abstract
The invention relates to a multipole commutator motor ( ) having at least four stator poles ( ) and having armature coils ( ) that work together with these stator poles and that, for the supply of power, are each connected electrically with two commutator bars ( ) of a commutator ( ), and whose number is greater than the number of the stator poles ( ), it being provided that, in order to reduce the number of brushes ( ) contacting the commutator ( ), armature coils ( ), that form armature poles having identical magnetic orientation are connected in parallel through electrical bridge conductors ( ) at the armature. For the commutator motor ( ), it is proposed that the bridge conductors ( ) be routed at least partially via armature slots ( ).
