The mechanism comprises at least one wedge element and a guide member. The guide member is attached to the second assembly and adapted for receiving the wedge element in a way that and at least an inactive position of the mechanism is defined where the first and second assemblies can be detached from each other, and an active position where at least one of the wedge element and the guide member presses against two different sectors of the first assembly such that the first assembly and the second assembly remain attached to each other.

Generator rotor comprising a rotor rim and a plurality of permanent magnet modules and a plurality of anchors arranged at an outer or inner circumference of the rotor rim such that the anchors substantially fix the permanent magnet modules to the rotor, wherein the permanent magnet modules comprise a base having a bottom surface, two axially extending side surfaces and a top surface, and one or more rows of magnets mounted on said top surface, wherein the two side surfaces of the permanent magnet modules each comprise an axially extending groove, and wherein the anchors have a shape that substantially fits exactly in axially extending grooves of neighbouring permanent magnet modules.
摘要:
In a first aspect, the invention provides a permanent magnet rotor for an electrical machine having a stator and a rotor and an air gap arranged between the rotor and the stator. The rotor has a rotor body configured for rotating around a central rotational axis and further comprises permanent magnets that are inserted in a magnetic material. The magnets have an inner end and an outer end, the outer end of the magnet being arranged in the proximity of the air gap at the circumference of the rotor delimiting the air gap, and at least a portion of the outer end of the permanent magnets is not covered by the magnetic material.
