Special Issue "Magnetic Bearing Actuators"
A special issue of Actuators (ISSN 2076-0825).
Deadline for manuscript submissions: 31 January 2019
Active magnetic bearings have several distinguishable advantages over other bearings—complete contact-free suspension of a rotating object, controllable and observable bearing force, lubrication-free and maintenance-free characteristics, etc. The range of applications steadily increases and novel systems are still being developed. This Special Issue is aimed at presenting this technology with a focus on the various aspects of actuators: Geometric design, choice of materials, modeling, analysis, measurement, control, and evaluation. Linear magnetic bearings for non-rotating objects are also targeted, even though “magnetic bearing” implies a rotating object.
Encouraged contributions related (but not limited) to novel configurations/functions, designs for special-condition operations, power amplifier and drive schemes, sensing/estimating techniques, sophisticated control schemes, coupled with motor drive, minimization of loss, and reduction of hardware, are welcome.Prof. Takeshi Mizuno

Abstract: Active magnetic bearings (AMBs) have attracted the attention of researchers to find new applications and make them viable for industrial applications. AMBs technology has now achieved a considerable level of maturity, and represents one of the most promising solutions for several applications involving rotating machinery. In such devices, the rotating shaft levitates suspended by magnetic forces, preventing from any wear due to mechanical contact between the bearings and the rotor journals. AMBs are lubricant free, reaching high speeds without any relevant heating. In this context, the present work is devoted to the design of a reduced model of an experimental test rig composed of a flexible shaft supported by two radial AMBs. For this purpose, this study was divided into two parts. The first part is dedicated to the development of individual numerical models to represent the dynamic behavior of each subsystem that composes the rotor system, as based on the design characteristics of each subsystem. Thereafter, the models of the subsystem are assembled together to obtain a representative model of the entire system. Then, model reduction techniques are applied to make the system simpler and still representative. Next step is the correlation of the numerical models with the experimental results for validation purposes. Based on the data obtained, the stability analysis of the system is performed by considering existing standards for magnetic bearings. The obtained results demonstrate the representativeness of the reduced model.
