  "textContent": "A method for operating an electric machine including a rotor and a stator is connected to a first or a second power electronics assembly (PEA), the first or the second PEA including a circuit arrangement that produces a freewheeling condition or an active short circuit condition for a winding of the rotor or the stator, to a DC voltage network having a battery, and the first or the second PEA including an inverter formed by the circuit arrangement. The method includes, in response to a primary fault signal indicating a fault the first or the second PEA, actuating the first or the second PEA to produce the freewheeling condition, and in response to a secondary fault signal indicating a nonreceptiveness of the battery for power fed by the electric machine to the DC voltage network, actuating both the first and the second PEA to produce the active short circuit condition.",
