摘要
A permanent-magnet synchronous machine includes a stator in which a stator winding is arranged, a rotor which can rotate about a rotation axis and in which permanent magnets are arranged, wherein the rotor is connected to a motor shaft via a connecting device which is formed such that it initially connects the rotor to the motor shaft in a rotationally fixed manner, such that a torque which is generated by the interaction of stator winding and permanent magnet is transmitted to the motor shaft, where the connecting device is further configured automatically break the rotationally fixed connection of the rotor in the event of a short circuit of the stator winding, such that a torque that acts on the motor shaft is no longer transmitted to the rotor.
