  • Another advantage of a single brush holder is that it is small, whereby the tools for the brush holder are small compared to conventional brush support structures. On a similar sized tool surface more brush plates are ejected per tool; solely by the better utilization of the available area. And that although at least two brush holders must be used per motor. The area left for a commutator with conventional brush plates is now used. Nevertheless, all three requirements mentioned above are met. Characterized in that the beginning of the holder is formed off-center on the carrier and is inclined to the radial of the arc, a "dragged brush" is realized in a simple manner.
