Abstract
A current discharge assembly for an electric machine in an electric vehicle, includes a rotor shaft defining a channel, a ground element positioned within the channel, and a connector positioned within the channel of the rotor shaft and extending circumferentially between the rotor shaft and the ground element. The connector is configured to electrically couple the rotor shaft to the ground element when the rotor shaft is rotating to allow current to flow from the rotor shaft to the ground element via the connector. Other example current discharge assemblies and methods for manufacturing current discharge assemblies are also disclosed.
