Multi-pole commutator motor comprising bridge conductors

The invention relates to a multipole commutator motor (14) having at least four stator poles (16-19) and having armature coils (31-42) that work together with these stator poles and that, for the supply of power, are each connected electrically with two commutator bars (1-12) of a commutator (22), a...

More Information
Summary:The invention relates to a multipole commutator motor (14) having at least four stator poles (16-19) and having armature coils (31-42) that work together with these stator poles and that, for the supply of power, are each connected electrically with two commutator bars (1-12) of a commutator (22), and whose number is greater than the number of the stator poles (16-19), it being provided that, in order to reduce the number of brushes (20, 21; 23, 24) contacting the commutator (22), armature coils (31-42), that form armature poles having identical magnetic orientation are connected in parallel through electrical bridge conductors (43-48) at the armature. For the commutator motor (14), it is proposed that the bridge conductors (43-48) be routed at least partially via armature slots (71-82).
