Definitions
- the present invention relates to a commutator for an electric machine with commutator, wherein on at least one Kommutatoriamelle at least one angled holding element for interconnecting contact conductors of the rotor winding and their justifyieru ⁇ g is formed with the respective commutator on a rotor winding Kommutatorlamelle.
- Commutators are used in electrical engineering for current application in electrical machines, in particular DC motors.
- Mechanically commutated DC motors are also referred to as commutator motors.
- Commutator motors are used, for example, for driving radiator fans in motor vehicles.
- a typical example of such a commutator motor has two pole pairs and thus four, preferably permanently excited, stator poles, and accordingly two brush pairs with correspondingly four brushes.
- the brushes grind over commutator blades of the commutator:
- DE 197 57 279 C1 it is known from DE 197 57 279 C1 to interconnect commutator bars of approximately twice the pole pitch by commutator blade contact bridges.
- the commutator lamella contact bridges are co-wound by winding wire during winding of the armature coils.
- the contact bridge conductors are hung in the same way as the wires of the rotor winding in grooves which are arranged on the commutator bars.
- the invention is therefore the object of developing a generic commutator such that a winding of rotors with multiple wires and their interconnection at the commutator without welding and contacting problems is possible.
- the commutator has a plurality of commutator blades. Furthermore, the commutator for shading the contact conductor, in particular the winding wires, the rotor winding and for contacting the wires with the respective commutator, at least one angled retaining element. On the commutator side facing the rotor winding, at least two angled holding elements are arranged on a commutator lamella.
- the advantage of the invention is that through the formation of at least two angled holding elements a reliable contact of several, d. H. at least three, contact conductors or winding wires can be ensured.
- the angled holding elements and the commutator are integrally formed.
- the commutator blade is designed such that the holding elements are bent or angled to the commutator bars.
- the holding elements are arranged side by side in the circumferential direction of the commutator bars.
- the holding elements can also be arranged one behind the other in the axial direction of the commutator bars.
- the holding elements are arranged next to one another in the circumferential direction of the commutator bars, the holding elements are advantageously arranged offset axially in the direction of the winding.
- This staggered arrangement allows a safe winding process, in particular a secure process for interconnecting the rotor winding.
- the holding element which serves to interconnect the commutator blade contact bridges, arranged deeper and / or offset relative to that holding element, which serves to interconnect the rotor winding.
- the holding elements of a commutator are arranged centrally with respect to the commutator.
- the commutator For insulation between the contact conductors or wires of the rotor winding and the rotor shaft, the commutator has a collar.
- the holding elements arranged on the commutator lamella are arranged on the commutator side facing away from the rotor winding.
- the angled holding elements are designed as hooks and preferably made of copper.
- Fig. 1 is a partial view of a sectional view of a first
- FIG. 2 is a schematic representation of a commutator blade according to the first embodiment of the commutator according to the invention
- Fig. 3 is a partial view of a sectional view of a second
- Fig. 4 is a schematic representation of a commutator blade according to the second embodiment of the commutator according to the invention.
- the commutator 1 shows a partial view of a sectional representation of a first embodiment of a commutator 1 according to the invention.
- the commutator 1 is arranged on a rotor shaft 2.
- the commutator has a plurality of commutator blades 3, wherein only one commutator 3 is shown.
- the commutator blades 3 have angled holding elements 4 and 5, which are arranged in the circumferential direction of the commutator blades 3 side by side.
- the holding elements 4 and 5 are arranged offset in the axial direction in order to provide a secure winding process.
- the holding element 5 is used for interconnecting the commutator bars-contact bridges, not shown, and is also arranged deeper relative to the holding element 4, which serves for interconnecting the rotor winding, not shown. As can be seen in FIG. 1, the holding elements 4 and 5 are bent or angled on the commutator lamella 3. For the isolation between the contact conductors or wires, not shown, of the rotor winding and the rotor shaft 2, the commutator 1 has a collar 6.
- Fig. 2 shows a schematic representation of a commutator blade 3 according to the first embodiment.
- the holding elements 4 and 5 are arranged side by side. It can be seen particularly well in FIG. 2 that the commutator lamella 3 and the holding elements 4 and 5 are formed in one piece. For this purpose, the commutator 3 is first separated or slotted at one end and then the holding elements 4 and 5 are bent.
- FIG. 3 shows a partial view of a sectional representation of a second embodiment of a commutator 1 according to the invention.
- the commutator 1 is arranged on a rotor shaft 2.
- the commutator has a plurality of commutator blades 3, wherein only one commutator 3 is shown.
- the commutator bars 3 have holding elements 4 and 5, which are arranged one behind the other in the axial direction of the commutator bars 3.
- the holding element 5 is used for interconnecting the commutator bars contact bridges, not shown, and is also lower than the Gareleme ⁇ t 4 arranged, which serves to shade the rotor winding, not shown. As can be seen in FIG. 3, the holding elements 4 and 5 are bent.
- the commutator 1 has a collar 6.
- FIG. 4 shows a schematic representation of a commutator blade 3 according to the second embodiment.
- the angled holding elements 4 and 5 are arranged one behind the other. First, the holding member 4 is bent and then the holding member 5 is bent.
