A discharge device for discharging electric currents in a machine from a rotor part to a stator part, the rotor part in particular having a shaft, the discharge device comprising a contact element and a spring being connectable to the stator part in an electrically conductive manner, the contact element made predominantly of carbon, the contact element pressurized with a contact force by the spring for realizing an electrically conductive sliding contact between a sliding contact surface of the contact element and an axial shaft contact surface of the shaft. The contact element is circular, the sliding contact surface being at least annular in shape and disposed coaxially in relation to the shaft contact surface, the spring includes a circular support section which at least in part coaxially envelops the shaft of the machine, the support section being configured for radially abutting against an abutment surface of the stator part.

Discharge device for discharging electric currents

The invention relates to a brush module () for a rotating electric machine, in particular for a current-excited synchronous machine, the brush module () having at least two brushes () for establishing electrical contact with slip rings () of the machine, the brush module () having a housing device () and brush holders () for accommodating and supporting the brushes (), wherein the housing device () has a collecting device () for collecting brush dust of the brushes (). Alternatively, the housing device () is configured in such a manner that the brush holders () are spaced apart from each other, the housing device () at least partially forming an air gap between the brush holders () on a housing portion of the housing device () that faces slip rings ().

Brush module

A discharging device for discharging electrical interference, in particular currents, from a rotor part of a machine, said rotor part in particular being a shaft, into a stator part () of the machine, the discharging device having a contact device () comprising a contact element () which is accommodated in an axially displaceable manner in a guide and which is acted on by a contact force device () for generating a shaft contact force (F) in order to establish electrical contact between a shaft contact surface () of the contact element () and a rotor contact surface () of the shaft (), wherein the guide has a stator contact surface () for forming an electrical connection with the stator part () and the discharging device has a guide contact force device () for generating a guide contact force (F) between a guide contact surface () of the contact element () and the stator contact surface () electrically connected to the stator part ().

Discharging device for discharging electrical interference
