| 摘要 |
This electric machine, notably a motor (2), comprises a stator (6), a rotor (8), a first main bearing (12), designed to support the rotor (8) with respect to the stator (6) in a main range of speeds, and a first secondary bearing (16) designed to support the rotor with respect to the stator when the first main bearing fails. The or each secondary bearing (16) is a passive electrodynamic bearing comprising at least one permanent magnet and a mobile electrically conducting element. Application to electric machines, notably to asynchronous or synchronous motors. |
