A dynamo-electric machine includes a laminated stator, a laminated rotor and a winding system disposed in the laminated stator and/or the laminated rotor and forming a winding overhang on end faces of the laminated stator and/or laminated rotor. The winding system includes a signaling line to detect interturn faults generated by a high heat. An insulation of signaling lines or a wire of the signaling lines is configured to be temperature-sensitive so that a melting point of the insulation or of the wire is about 30 degrees Kelvin above the temperature class of the dynamo-electric machine.

Dynamo-electric machine comprising a signaling system for recognizing short circuits in the winding system

The invention relates to a drive system (). The drive system () has at least two inverters () and at least two motors (). Each of the motors (), each of which has a stator and a rotor, has at least one first coil system () and a second coil system () in the stator. Each first coil system () is connected to a first inverter () in an electrically conductive manner, and each second coil system () is connected to a second inverter () in an electrically conductive manner. The invention further relates to a method for the redundant operation of a drive system (), wherein at least one motor exchanges electric energy with the second inverter () and/or one or more additional inverters () if the first inverter () fails.
