초록

Device for magnetic suspension of a rotor (10, 20, 30) in relative rotational movement along a predetermined rotation symmetric path with respect to a stator (14, 24, 26, 34, 36). Rotor (10, 20, 30) comprises a rotational body (11, 21, 31) which essentially consists of an electrically conductive unmagnetic material. Fitted at the stator (14, 24, 26, 34, 36) is at least one magnetic member (12, 22, 25, 32, 35), which comprises at least one rotation symmetric magnet (12, 22, 25, 32, 35) concentric with the rotational axis. The magnetic member is disposed t...
