Dynamic and thermal modeling of touch-down bearings considering bearing non-idealities
(Lappeenranta-Lahti University of Technology LUT, 2020-06-26)
In an active magnetic bearing (AMB) supported rotor, the touchdown bearings support the rotor in case of an electromagnetic field failure or a fault in the control system. In this work, a dynamic and thermal model of ...
