Active magnetic bearing-supported rotor with misaligned cageless backup bearings: A dropdown event simulation model
A dynamic model of cageless backup bearing of an AMB system is proposed. A simulation model is used to study the effect of bearing misalignment. The model is verified by comparing the simulations to measurements. A parametric study of a system with two misaligned cageless backup bearings is done. The dropdown is found to be fatal when misalignment is 75% of the air gap.
