Abstract:
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.

Claim (Index 19):
The synchronous machine as claimed in  claim 14 , wherein the rotor is supported to rotate on the motor shaft;\n wherein the connecting device comprises a ring, which is connected to the rotor in a torsion-proof manner at an axial end of the rotor; wherein the connecting device comprises at least one bolt, which is arranged partly in a recess of the ring and partly in a recess of the motor shaft, such that the torque generated by the interaction of stator winding and the permanent magnets is transmitted via the at least one bolt to the motor shaft; wherein the connecting device comprises a retaining element via which a radial displacement of the at least one bolt from the recess of the motor shaft is initially prevented; and wherein the retaining element consists at least partly of a material, of which at least one of (i) the strength and (ii) the cohesion is reduced such that, in the event of the short circuit of the stator winding, by at least one of (i) the occurrence of overheating of the stator winding and (ii) the occurrence of arcs, the bolt is displaced from the recess of the motor shaft.
