Abstract

The present disclosure relates to electrical machines comprising a rotor (13), a stator (12) and a radial air gap (39) between the rotor (13) and the stator (12), wherein one of the rotor and stator comprises an endplate driven on one side of the electrical machine, a central support (32) radially surrounding the other of the rotor (13) and stator (12), and a stiffener ring (33) on an opposite side of the electrical machine. The stiffener ring comprises an outer ring (34) connected to the central support (32), and an inner ring (35) connected to the outer ring (34). The outer ring (34) comprises a plurality of removably mounted outer segments (44). The present disclosure further relates to wind turbines and to methods for repairing parts of an electrical machine.
