Abstract

A method for operating an electric machine having a power inverter, which is electrically connected to a relative ground potential, and a ground differential voltage between the relative ground potential and a reference ground potential is monitored, and if the ground differential voltage reaches an upper limit value, the electric machine is operated in a current-delivering operating state, and if the ground differential voltage reaches a lower limit value, the electric machine is operated in a non-current-delivering operating state.
