Abstract
A high-speed rotor, in particular a permanent-magnet rotor (1) for dynamoelectric machines of high power density, and also its production are proposed. The permanent-magnet rotor (1) comprises a spindle (2) and armouring (4) coaxial with the spindle (2), a number of ceramic permanent magnets (3a-3d) that are distributed between the spindle (2) and the cylindrical sheath (4), and also a gap-filling filling compound. Said filling compound made of filled polymers seals the gaps in the permanent-magnet rotor (1) by injection moulding. Due to the remanent pretension, the permanent magnets (3a-3d) remain permanently rigidly joined even against high centrifugal forces.
Claims11
High-speed rotor, in particular permanent-magnet rotor (1) for dynamoelectric machines of high power density, comprising at least one spindle (2) and a cylindrical sheath (4) coaxial with the spindle (2), and also a number of bodies (3) that are distributed between the spindle (2) and the cylindrical sheath (4), characterized in that a cavity-filling, compressed and cured filling compound is used for the pretensioned sealing and rigid joining of said parts (1, 2, 3, 4).
