Abstract
A brush holder for slipring brushes comprises a brush mount held by a lever at a base. The lever is connected by a base pivot to the base and is pivotable in a plane orthogonal to a brush mount pivot axis and/or to a slipring rotation axis. A spring is provided between the base and the lever. The brush mount is connected to the lever by a brush mount pivot pivotable in said plane. The brush mount holds a first brush and a second brush wherein the brush mount pivot is between the first brush and the second brush.
Claims56
A brush holder comprising:
- a brush mount held by a lever at a base, wherein the lever is pivotably connected by a base pivot to the base, the base pivot having a base pivot axis,
- a spring disposed between the base and the lever,
- wherein the lever is limited in its movement within a first plane orthogonal to the base pivot axis,
- wherein the brush mount is connected to the lever by a brush mount pivot, the brush mount pivot only having a first pivot axis parallel to the base pivot axis;
- wherein the brush mount comprises at least a first brush fixation means and a second brush fixation means wherein the brush mount pivot is between the first brush fixation means and the second brush fixation means, and
- wherein a distance between the first brush fixation means and the brush mount pivot is larger than the distance between the second brush fixation means and the brush mount pivot.
A brush holder comprising:
- a brush mount held by a lever at a base, wherein the lever is pivotably connected by a base pivot to the base, the base pivot having a base pivot axis,
- a spring disposed between the base and the lever,
- wherein the lever is limited in its movement within a first plane orthogonal to the base pivot axis,
- wherein the brush mount is connected to the lever by a brush mount pivot, the brush mount pivot only having a first pivot axis parallel to the base pivot axis;
- and
- wherein an active brush contact area on a first side of the brush mount pivot is at least 10% larger than an active brush contact area on a second side of the brush mount pivot.
A brush holder comprising:
- a brush mount held by a lever at a base, wherein the lever is pivotably connected by a base pivot to the base, the base pivot having a base pivot axis,
- a spring disposed between the base and the lever,
- wherein the lever is limited in its movement within a first plane orthogonal to the base pivot axis,
- wherein the brush mount is connected to the lever by a brush mount pivot, the brush mount pivot only having a first pivot axis parallel to the base pivot axis;
- wherein the lever comprises a first lever section that holds the brush mount and a second lever section to which the spring is attached, wherein the base pivot is between the first lever section and the second lever section;
- and
- wherein the second lever section is shorter than the first lever section.
