Abstract

Zur Minderung des axialen Einbauraums bei gleichzeitig einfacher Fertigung sind die Kommutator-Haken (2;3) mit ihren freien, zu ihrer Verankerungsebene (2.2;3.2) in dem Kommutator abgewandten Enden als beschleifbare Lamellen (2.1;3.1) ausgebildet und nach Aufnahme, insbesondere Umschlingung, von zumindest einem Wicklungsdraht (6;7) in die Ebene der Bürstenschleiffläche (4.1;5.1) gebracht; in vorteilhafter Weise ist dabei die gesamte axiale Länge des Kommutators als Bürstenschleiffläche ausnutzbar.

Figure 00000002
To reduce the axial installation space while at the same time being simple to manufacture, the commutator hooks (2; 3) are designed with their free ends facing away from their anchoring plane (2.2; 3.2) in the commutator as lamellas (2.1; 3.1) that can be ground and, in particular, after reception Looping, brought by at least one winding wire (6; 7) into the plane of the brush grinding surface (4.1; 5.1); the entire axial length of the commutator can advantageously be used as a brush grinding surface.
