#CMT# #/CMT# The machine (10) has a slip ring (18) arranged at a rotor shaft (12), and two sliding contacts arranged at the circumference of the slip ring for producing an electric contact with the slip ring. A suction device (34) is arranged between the sliding contacts directly over the slip ring for sucking wear debris developed at the slip ring, and a gap is provided between the suction device and the slip ring. #CMT# : #/CMT# An independent claim is also included for a method for retrofitting an electric machine with a rotor shaft. #CMT#USE : #/CMT# Used as an electric generator for converting mechanical energy into electric energy, in a thermal power station e.g. steam power station, and as an electric motor for converting electric energy into mechanical energy. #CMT#ADVANTAGE : #/CMT# The suction device sucks the wear debris developed at the slip ring, thus effectively avoiding accumulation of the wear debris at the slip ring in a cost-effective manner. The suction device is arranged between the sliding contacts directly over the slip ring for sucking abrasion developed at the slip ring, thus reducing constructive complexity of the suction device, and hence eliminating the need for re-designing of the sliding contact. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective view of an electric machine. 10 : Electric machine 12 : Rotor shaft 16 : Support plate 18 : Slip ring 34 : Suction device. |
