1. A discharge device for discharging at least one of an electrical charge or voltage from a rotor of an electric motor from a first discharge partner to a second discharge partner, the discharge device comprising:
a support body device having a connecting portion for electrical and mechanical connection to one of the discharge partners; and
a contact device having a contacting portion for electrical connection to an other of the discharge partners, and the contact device being connected to the support body device;
wherein the support body device has expanding portions for expanding the connection of the support body device to one of the discharge partners, and the expanding portions have the connecting portion; and
wherein one of the discharge partners is a housing, and the expanding portions are pre-loaded radially outwards against the housing.
