1-15. (canceled)
An electrical machine, comprising:
- a rotor rotatably mounted for rotation around a rotor shaft;
- at least one outer bearing mounting said rotor at a radial distance from said rotor shaft;
- and
- said rotor shaft being connected to said rotor for transmitting rotational movements of said rotor to said rotor shaft;
- and
- a connection between said rotor and said rotor shaft enabling an axial relative movement between said rotor and said rotor shaft.
3 more elements
A bearing arrangement for a machine having a rotor shaft, a rotor rotatably mounted for rotation about the rotor shaft, the bearing arrangement comprising:
- at least one outer bearing mounting the rotor at a radial distance from the rotor shaft;
- a connection between the rotor and the rotor shaft configured to transfer a rotary movement of the rotor to the rotor shaft, said connection further enabling an axial relative movement between the rotor and the rotor shaft.
