  "textContent": "The invention relates to a method for operating an electric machine () comprising a rotatably mounted rotor () and at least one motor winding (). In said method, a temperature load of the machine () is ascertained, and an electric motor current is applied to the motor winding () to generate a specified desired torque (N) according to the temperature load. According to the invention, when a temperature load is ascertained that exceeds a specified load threshold, a field strengthening mode of the machine () is activated, in which field-strengthening mode the motor winding () is energized in such a way that the motor current has a positive field-forming current component (Id).",
