Abstract
An insulating disc for an electric machine, which has a slip-ring module, which is arranged on the rotor shaft of the rotor of the electric machine, and a brush module, which is arranged on the housing of the electric machine. The insulating disc comprises an insulating face which is designed to spatially shield the brush area, which is formed by the slip-ring module and by the brush module, from the housing. The insulating disc also comprises one or more fastening elements which make it possible to fasten the insulating face to the brush module and/or to the housing of the electric machine.

1-16. (canceled)
An insulation disk for an electric machine, comprising:
- a slip ring module, arranged on a rotor shaft of a rotor of the electric machine, and a brush module, arranged on a housing of the electric machine;
- wherein the insulation disk comprises:
- an insulation surface which is configured to shield a brush space, formed by the slip ring module and by the brush module, spatially from the housing;
- and,
- one or more fastening elements which are configured to fasten the insulation surface to the brush module and/or to the housing of the electric machine.
A method for electrically insulating a brush space of an electric machine from a housing of the electric machine, wherein the brush space is formed by a slip ring module, arranged on a rotor shaft of a rotor of the electric machine, and a brush module, arranged on a housing of the electric machine, the method comprising:
- arranging an insulation surface between the housing of the electric machine and the brush module, with the result that the insulation surface shields the brush space spatially from the housing.
