Abstract (en)
[origin: US5909077A] PCT No. PCT/EP96/00001 Sec. 371 Date Oct. 21, 1997 Sec. 102(e) Date Oct. 21, 1997 PCT Filed Jan. 2, 1996 PCT Pub. No. WO96/21260 PCT Pub. Date Jul. 11, 1996The invention describes a carbon brush for an electrical machine. Carbon brushes of this type need to fulfill two requirements. First, the carbon brush should be as resistant to abrasion as possible. Second, as little noise as possible should be generated at the brush/collector crossover during the operation of the motor. Consequently, the invention proposes to bevel the face surface of the carbon brush, and to provide the face surface with transverse grooves within its lower region.
