Claim:
1. A multi-phase electric circuit, comprising: an electric machine comprising a stator and a rotor, the stator being configured to connect to an electric energy supply grid; an inverter configured to connect to the electric energy supply grid; the rotor being connected to the inverter via at least two brushes for each phase, and each of the at least two brushes of each phase is connected to the inverter via a separate brush line; a multi-phase short-circuiting device connected to the brush lines coupling the rotor to the inverter; and each of the brush lines being connected to the multi-phase short-circuiting device via a short-circuiting impedance, the impedance being a resistor and an inductor connected in series within the brush line, and wherein the multi-phase short-circuiting device is embodied to short-circuit the phases connected to the multi-phase short-circuiting device.
