Abstract
An apparatus for protecting an electrical machine in the event of a fault, the electrical machine having six phase terminals includes a monitoring unit for detecting a fault of the electrical machine and a switchover unit for switching the electrical machine from a normal operating state into a short-circuit operating state if a fault of the electrical machine is detected. The switchover unit is designed to short-circuit the six phase terminals of the electrical machine asynchronously in accordance with a predefined pattern.
