The application of magnetic bearings has become more frequent during the last 20 years and represents a significant aspect improvements in construction machines with rotary motion. With advancement technology, number applications which have found their is increasing. In this paper, it shown how effect forces can annul negative influence unbalance, suddenly appeared rotor supported active bearin...

This paper explores the experimental issues associated with the implementation of the recently developed generalized complementary flux constraint (GCFC) flux-biasing scheme on a spacecraft reaction wheel that is magnetically suspended by a low-loss active magnetic bearing (AMB). Implementation of the GCFC depends fundamentally on the ability to estimate the electromagnet flux. Once addressed, ...

Magnetic levitation is an interesting phenomenon of lifting/ suspending objects without any physical contact using magnetic power, which finds multitude of applications in modern technologies. The objective of this article is to interactively demonstrate magnetic levitation using a simple experimental setup with intent to increase the efficacy of science and engineering pedagogy in teaching-lea...

A signal processing technique is presented by which the position of a rotor supported in magnetic bearings may be deduced from the bearing current waveform. The bearing currents are presumed to be developed with a two state switching amplifier which produces a substantial high frequency switching ripple. This ripple is demodulated using a model reference parameter estimation technique which ext...
