Abstract
A magnetically levitated rotor includes a magnetically effective core and a sheathing made of a thermoplastically processible fluoropolymer. The sheathing completely encloses the magnetically effective core. The magnetically effective core comprises at least one permanent magnet and each permanent magnet has a metallic coating for protection against acidic or chemically aggressive substances. A plastic coating is disposed between the metallic coating and the sheathing, and includes a polymer belonging to the family of parylenes.
