Delevitation modelling of an active magnetic bearing supported rotor
(2014)The problem addressed in this thesis is the delevitation modelling of an active magnetic bearing (AMB) supported rotor. A system model needs to be developed that models the highly non-linear interaction of the rotor with ... -
Experimental validation of a rotor delevitation model with quantified severity indicators
(Elsevier, 2018)This paper presents the experimental validation of BBSim: a non-linear model for simulation of rotor delevitation in an active magnetic bearing system with backup bearings (BBs). The rotor delevitation model’s purposes are ... -
Investigation into backup bearing life using delevitation severity indicators
(North-West University (South Africa) , Potchefstroom Campus, 2016)Active magnetic bearings (AMBs) are inherently flawed in terms of possible failure from either mechanical, electronic or software components. Component failure could induce a rotor delevitation event (RDE) during operation ... -
Non-linear model of rotor delevitation in an active magnetic bearing system including parameter estimation
(Elsevier, 2017)Backup bearings (BBs) are used to protect active magnetic bearings in the event of rotor delevitation. To gain insight into the design, selection and operation of BBs, a model that can accurately simulate the behaviour of ...
