ABSTRACT OF THE DISCLOSURE
A rotor arrangement for an electrical machine,
specifically for a transversal flux machine. The rotor
is in peripheral direction provided in alternating
succession and in an annular arrangement with a plurality
of polarized magnets and magnetizable collector elements.
In axial direction, the rotor features a rotor disk that
can be secured to the rotor shaft and to which rotor disk
the polarized magnets and the magnetizable collector
elements are secured in a concentric annular arrangement.
For fastening, fasteners are employed which extend
through the polarized magnets and are secured to the
rotor disk or an axially spaced insulating ring element
joined to the rotor disk.
