ABSTRACT:
In a method for fabricating a permanent magnet rotor for an electrical machine, a rotor support having an axis of rotation is provided. At least two poles are provided on the rotor support, each pole having at least one permanent magnet. A screen made essentially from a highly conducting material is provided on the surface of the permanent magnets facing a stator of the electrical machine. The screen is applied galvanically. On the screen an annular fiber reinforced support is fitted. The rotor support comprises two partially conical parts interacting with each other to prestress the rotor radially.
