ELECTRODYNAMIC MAGNETIC BEARING
Device for magnetic suspension of a rotor (10, 20, 30) in relative rotationa l 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 un...

| description | Device for magnetic suspension of a rotor (10, 20, 30) in relative rotationa l 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 means (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 means is disposed to give rise to a rotation symmetric magnetic field concentric with the rotational axis. When and only when the rotational body (11, 21, 31) tends to leave the predetermined path and rotate eccentric, the magnetic field generates induced eddy currents in the rotational body (11, 21, 31), said eddy currents give rise to restoring stabilising forces. |
