  • Brush arrangement for an electric machine
    Patent number: 7420311
    Abstract: A brush device for an electric machine having at least one brush and at least one element such as a helical, scroll, or plunger spring for pressing each brush against a rotating contact element, for example a commutator. In at least one further element for example a spring tab, counteracts a lifting of each brush away from the contact element. To this end, the spring tab is inclined at an angle, as a result of which it exerts a weaker action when the brush moves in the direction toward the contact element than it does counter to this direction. As a result, the brush can be repositioned, but is prevented from lifting away from the contact element. This also reduces the danger of vibrations.
