    摘要: A demagnetization system for demagnetizing magnet elements (10) of a wind turbine generator component is provided. Each magnet element (10) comprises at least one permanent magnet block (15). The demagnetization system (100) comprises at least one heating station (21, 22), wherein each heating station comprises an induction heater (30) configured to heat a magnet element (10) and an automatic transport system (50) configured to transport each magnet element (10) to each of the at least one heating station (21, 22), wherein the demagnetization system (100) is configured to heat the magnet element (10) at each heating station (21, 22) by means of the respective induction heater (30).

    摘要: Disclosed is a housing wall (100) for a rotor housing of a rotor (40)for an external electric power generator (10) of a, for example direct-drive, wind turbine, or a housing wall (100) for a rotor housing of a rotor for an external rotor of an electric machine, for example an electric generator or an electric motor. The housing wall (100) is an outer housing wall and has: an inner wall surface (110), an outer wall surface (114) and an axial length (124). The inner wall surface (110) is cylindrical. The outer wall surface (112) has at least one indentation (130), which extends over at least a part of the axial length (124), in particular over the total axial length (124), of the outer wall surface (112). The outer wall surface (112) may have a plurality of such indentations (130). The indentations (130) may, or may not, be equally spaced along the circumferential direction (108) around the outer wall surface (112). The indentations (130) may extend at a spiral angle (132) with respect to the axial direction (104) of the housing wall (102). The at least one indentation (130), in particular each indentation (130), may have, when viewed parallel to an axial direction (124) of the housing wall (102) in a cross-section that contains a cylinder axis (104) of the housing wall (102), a cross-sectional shape that is selected from the group that includes a substantially rectangular shape (140), a substantially trapezoidal shape (142), a substantially zig-zag shape (144), a substantially undulating shape (146).
