Abstract
A combined cooling and abrasion particles removal system and method for providing cooling and removing abrasion particles in a contact region between a brush and a slip ring of an electromechanical machine, the system comprising a passage for accommodating the brush and having a front opening adapted to face the slip ring, at least one supply tube with an outlet for blowing a gaseous medium at least partially into a direction towards a free space adjacent to the front opening, and at least one suction tube with an inlet opening for sucking off the gaseous medium and the abrasion particles from the free space. In order to pick up abrasion particles and provide sufficient cooling, the free space merges with a vortex chamber for generating a vortex of the gaseous medium carrying the abrasion particles in operation of the system.
