A method for fastening permanent magnet magnetic poles to the rotor of an electric machine, rotor and mould for fastening the permanent magnets

摘要

The method involves forming magnetic poles to a support surface (1) of a rotor ring (2) of an electrical machine e.g. synchronous machine, and forming a mold by attaching a mold part (4) to the surface. A mold cavity of the mold is limited on a side by the surface. A permanent magnet (25) is inserted into the mold, and the inserted magnet is held in the mold in a desired position with respect to the surface. A hardened adhesive is filled into the mold, under adhesion of the magnet with the surface between the magnet and intermediate spaces forming a wall of the mold cavity.
