The technical literature on this topic is extensive as can be seen from several recent reviews ( 1 2 3 4 ). durability electric machines engines fracture toughness...

... the controllability of the rotor system and the elimination of oil supply. However, both bearings also have their limitations. JBs are limited by the instability mechanism known as oil whirl and oil whip ( 2 3 ), while AMBs have lower load capacity and tend to be larger for the same load. damping electric...
