Definitions
- the invention relates to a disk commutator and a drum commutator for an electric motor with at least two commutator blades, which in turn comprise an abrasive surface segment for contacting a carbon brush, wherein the abrasive surface segments are electrically separated from one another.
- the object of the present invention is therefore to design a commutator for electric motors in such a way that an improved commutation behavior is achieved.
- This object is achieved by referring to a pulley commutator in conjunction with the preamble of claim 1 in that the electrical separation of the grinding surface segments is inclined at an angle ⁇ to a commutator diameter.
- the invention is solved in conjunction with the preamble of claim 3 in that the electrical separation of the key surfaces in the longitudinal direction of the drum commutator inclines at an angle .beta.
- Drum commutator includes. Due to the new geometry of the commutator, d. H.
- the electrical separation in practice corresponds to a gap between two grinding surface segments - a longer commutation time is achieved ,
- the angular interval is increased, in which the carbon brush is in contact with (a plurality of grinding surface segments of) a plurality of commutator bars - and thereby increases the duration (commutation duration) in which at least one coil is short-circuited.
- the electrical separation between the individual grinding surface segments does not extend from the commutator axis of rotation radially outward, but is inclined at an angle ⁇ with respect to the commutator diameter.
- the optimization is based on the calculation of an optimal geometry for the longest possible commutation time of the grinding surface segments under consideration of cost-effective manufacturability.
- the angles .alpha. Or .beta. Therefore have values which are optimized under the criterion of a possibly long commutation duration.
- 1 shows the geometry of the grinding surface segments and the arrangement of their electrical separation (column) of a Scheib enkommutators according to the prior art
- 2 shows the geometry of the grinding surface segments and the arrangement of their electrical separation (column) of the disk commutator according to the invention
- FIG. 3 shows a three-dimensional view of the geometry of the closing surface segments and the arrangement of their electrical separation (column) of the disk commutator according to the invention with a carbon brush,
- Fig. 6 a
- the pulley commutator 1 shows schematically the geometry of the grinding surface segments 4 of a disk commutator 1 according to the prior art.
- the pulley commutator 1 has eight commutator blades 3 with j there is an abrasive surface segment 4, the individual commutator blades 3 and their abrasive surface segments 4 being separated from each other by radially extending electrical separations 6 (gaps). This results in a achsensymmetri cal subdivision of the disc surface in turn achsensymmetri cal grinding surface segments. 4
- the electrical separations 6 (gaps) between the commutator disks 3 and the grinding surface segments 4 are inclined at an angle ⁇ to a commutator diameter.
- 3 shows a three-dimensional view of the geometry of the grinding surface segments 4 of the disk commutator 2 according to the invention with a carbon brush 8.
- FIG. 5 shows the decay behavior of the current of a coil through the transverse resistance of the brush, simulated on the new commutator 2 (inventive commutator geometry) and on the commutator 1 according to the prior art for comparison. It can be seen that, based on the relative decay behavior of the current, it is approximately 1 5% higher reduction is achieved. It can be seen from the time axis (X-axis) in FIG. 5 that the commutation at the same rotational speed (9000 rpm) on the novel commutator 2 is approximately 0.1 ms, thus approximately 10 % s lasts on the geometry of the prior art.
