ABSTRACT:
An electrical machine in which power is supplied to the rotor via brushes and sliprings having an improved brush-dust suction apparatus, including brush supports and ring-shaped collecting chambers which are penetrated by brush bolts. The suction openings of these collecting chambers circumscribe the slipring in a ring pattern. Each collecting chamber is connected by thick-walled glass cylinders to a common collecting chamber, which is connected to a negative pressure source, when the air and the brush dust entrained in the air is conveyed to an exterior chamber. The brush supports are fastened by insulators to the collecting chamber and are mutually reinforced by insulator bolts.
