Device for cleaning collectors for electric motor operated with carbon brushes, has cleaning module on stator with movable cleaning brush pressed onto collector by spring and retracted by electromagnet

摘要

The cleaning device has a cleaning module (1) mounted on the electric motor's stator with a movable cleaning brush that is pressed onto the collector (5) by a spring and retracted by an electromagnet when an electric voltage is applied to the electric motor. The cleaning brush consists of a carbon brush provided with diagonally applied glass fibers at least on the side facing the collector.
