Abstract
The invention relates to a method for operating a multiphase electrical machine () in the event of a fault, wherein the electrical machine () is driven with the aid of a driver circuit (), wherein the driver circuit () has half-bridge circuits (), each associated with a phase (U, V, W), and bridge paths () for connecting or disconnecting predetermined voltage potentials to/from the respective phases (U, V, W) of the electrical machine (), wherein one or more of the bridge paths () are operated according to a first fault operating mode if a fault is detected, wherein, in the first fault operating mode, the one or more bridge paths () are controlled in such a manner that said paths connect a first of the predetermined voltage potentials to the phase (U, V, W) via a predetermined electrical resistor.
