Abstract (en)
[origin: EP2549113A2] The rotor (1) has a permanent magnet (8) sheathed within an outer encapsulation (6) by a metal casing (7), where the rotor is encapsulated by the encapsulation. The encapsulation comprises fluoridated hydrocarbon. The permanent magnet is connected with the metal casing in a form- and/or force-fit manner. The metal casing is connected with the encapsulation in a form- and/or force-fit manner. A recess (9) is formed between the permanent magnet and the metal casing. A thermal compensation unit (10) compensates different thermal expansions of the metal casing and/or the permanent magnet. An independent claim is also included for a rotary pump.
