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.

An electrical axial flux machine including a rotor shaft is provided. The rotor shaft is rotatable about an axis of rotation. Two rotors are arranged on the rotor shaft. The two rotors are spaced apart when viewed in a direction of the axis of rotation. The axial flux machine further includes a stator arranged between the two rotors when viewed in the direction of the axis of rotation. The stator includes stator teeth. Each of the stator tooth extends in the direction of the axis of rotation between two end regions. The stator teeth are arranged and distributed uniformly around the axis of rotation at a radial spacing from the axis of rotation and include a stator winding system. At least one ring structure is provided connecting the two end regions of the stator teeth. A housing further surrounds the stator radially on the outside.
