초록

A foil bearing operable with a magnetic field providing for magnetic suspension of a shaft. In one embodiment, the bearing construction relies upon a plurality of magnetic field generating members arranged to provide a shaft forming space to envelopingly receive the shaft and effectively suspend same in a composite magnetic field. In one embodiment, each of the magnetic field generating member include coils which are energizable with an electric current. In another embodiment, the magnetic field generating members comprise permanent magnets which are use...
