- a centrifugal force can be achieved. witnessed elongation of the rotor cap by the temperature shrinkage are significantly suppressed, which assists a secure fit of the rotor cap.
- fiber reinforced plastic is highly corrosion resistant.
- ⁇ is in that fiber-reinforced plastic is standard unmagne ⁇ table.
- the runner cap can be formed flexible and varied by the use of the fiber reinforced plastic. Production costs and production times can also be significantly reduced as there is no need for a complex forging process and reworking process. In addition, material costs can be significantly reduced by a substitution of a high-alloy steel by the fiber-reinforced plastic. Fiber reinforced plastic is sufficient and available without difficulty.
- the fiber-reinforced plastic can be referred to as a plastic ⁇ matrix / fiber composite material.
- the fibers have at least one preferred direction.
- a particularly high strength in the direction of particularly high stresses can be achieved, which reduces a probability of failure, for example due to cracking, and increases a lifetime ⁇ .

- me ⁇ chanical stresses, in particular tensile stresses, which are based on a centrifugal force caused by circumferential extent be considered.
- a direction of an azimuth changing ⁇ angle with respect to an axis of rotation or longitudinal axis of the Läu ⁇ ferkappe can be understood in particular.
- the at least one preferential direction ⁇ comprises exactly one preferential direction, the fibers are thus at least locally oriented unidirectionally. As a result, a particularly high strength can be achieved in this preferred direction.
- the fibers may be or may have been provided in particular as a (bulk) unidirectional Fa ⁇ fibers, as a fiber fabric and / or a fiber scrim.
- the fibers comprise or are carbon fibers.
- Carbon fibers have the advantage of enabling high strength matrix / fiber composites, being inexpensive, widely available, easy to handle in manufacturing, and also electrically conductive.
- the fibers Kera ⁇ have micro fibers. Ceramic fibers have the advantage of a particularly high tensile strength and ductility as well as high temperature resistance .
- the ceramic fibers may in particular be oxidic ceramic fibers, in particular aluminum oxide fibers or silicon dioxide fibers.
- the ceramic fibers may alternatively or additionally be non-oxide ceramic fibers, in particular silicon carbide fibers.
- the fibers have boron fibers. These have an extremely high strength and rigidity.
- the fibers have aramid fibers.
- Aramid fibers are characterized by a very high strength, a high impact strength, a high Bruchdeh ⁇ tion, a good vibration damping and high resistance to acids and alkalis. They are also very heat and fire resistant. It is also an embodiment that the fibers are embedded in a plastic matrix of resin, in particular epoxy resin. Epoxy resin is well known and manageable as a matrix material for fibers. Epoxy resin is also high
- the rotor cap can be produced with respect to its fiber-reinforced plastic, for example by means of a filament winding ("filament winding"), by means of transfer molding (also referred to as "Resin Transfer Molding", RTM) and / or by means of a prepreg technology.

- a material of the insert ring has ⁇ in particular a lower electrical resistance than the fiber-reinforced plastic. This may prevent ⁇ that flowing high currents to at an unbalanced load of the rotor in the rotor cap to excessively high temperatures in the rotor cap.
- the rotor cap is thus attached to the rotor so that the fiber-reinforced plastic rests at least partially over the insert ring on the rotor.
- the insert ring is intended to rest on rotor teeth of the rotor.
- the insert ring is made of metal. This makes it possible to provide a particularly inexpensive and electrically highly conductive metal insert ring, in particular since no high mechanical requirements need to be placed on the metal. At the same time, the use of the insert ring results in improvements with regard to the mechanical properties of the rotor cap and with regard to simplification in the application. It is a special design that the insert ring is made of steel with a low alloy content. This is particularly inexpensive and has a sufficiently low electrical resistivity. It is a special embodiment that the insert ring is made of copper or an alloy with it. Copper has a particularly low electrical resistivity.

It is a case in which the insert ring on its inside has a thread, advantageous embodiment that is a matching to the thread of the insert ring Ge ⁇ gengewinde on bearing surfaces of rotor teeth of the rotor.
- This mating thread can be produced for example by a material-removing process or by gluing, screwing, welding or soldering of thread guides on the bearing surfaces of the rotor teeth.
- the rotor cap by means of an additional or alternative fixation in the form of a second screw (in particular lock nut) can be fastened to the rotor.
- the runner can set up the runner cap to make a bayonet connection with the runner cap.
- the rotor cap has first been cooled down to be mounted on the rotor and then shrunk onto the rotor. It is exploited that fiber-reinforced plastic at least in the fiber direction has a negative coefficient of thermal expansion, ie expands with decreasing temperature. Consequently, it will become In particular, a rotor cap suitable extend, in which the fibers are aligned substantially in the circumferential direction. In the cooled state, the rotor cap consisting of the fiber-reinforced plastic or its basic body can be pushed onto the rotor (and possibly onto the insert ring). By a subsequent heating the rotor cap or its body is shrunk onto the rotor. This method can also be considered as being inventive in its own right.
- the object is also achieved by an electric Genera ⁇ tor, in particular turbo-generator, with at least one rotor or with at least one rotor cap as described above.
- the generator has the same advantages as the rotor cap and the rotor and can be configured in an analogous manner.
