    摘要: In a method for operating an at least three-phase electric machine used as a drive assembly in a motor vehicle, which is actuated via an inverter, the inverter including switching elements in the form of half bridges which are in each case electrically connected to a respective phase of the electric machine, when a first switching element of a first half bridge connected to a first phase is permanently closed/opened on account of failure, a second switching element of the first half bridge is permanently opened/closed and, in a first angular range of an electrical rotation, which is uninfluenced by the first phase, all switching elements of the additional half bridges are actuated in the usual manner.
