A rotor grounding system for an electric machine includes a rotor including a shaft assembly configured to rotate about an axis. A housing supports the shaft assembly for rotation of the rotor. A bearing assembly has an outer circumference disposed against the shaft assembly. A discharge bar extends through at least a part of the bearing assembly. The bearing assembly has an inner circumference disposed against the discharge bar. A discharge circuit is defined between the rotor and the housing, where the discharge circuit extends through the bearing assembly and the discharge bar.
