A review of large scale applications of high current and high field superconductivity is given. Requirements to and properties of technically used superconductors are discussed. Superconducting magnets as research tools are widely used in elementary particle and solid state research. Applications of superconductivity for industrial purposes seem to be promising for electrical machinery, magneti...

Magnetic levitation is a popular topic of research over the years throughout the world due to its wide range of industrial applications. In any DC attraction type suspension system, actuator and guide-way (rail) plays most important role. In this manuscript FEM based analysis of different structures of actuator and rail (guide-way) has been carried out utilizing ANSYS software. Input power to l...

Results on design, fabrication, and testing of silicon micromachined magnetic actuators are presented. Electroplated, low-stress permalloy (Ni80Fe20) material is the medium for magnetic interaction and force generation. The permalloy piece is supported by a structural plate, which consists of polycrystalline silicon thin film prepared by low-pressure chemical vapor deposition (LPCVD). Magnetic ...

This paper presents the simulation of the dual electromagnet Active Magnetic Levitation System realized in the COMSOL Multiphysics software. The mixed mode of Partial Differential and Ordinary Differential Equations is used to realize the levitated object motion. Two control scenarios are given as illustrative example of the working model.

In this paper, we propose a nonlinear model for magnetic levitation systems which is validated with experimental measurements. Using this model, a nonlinear control law based on differential geometry is firstly synthesized. Then, its real-time implementation is developed. In order to highlight the performance of the proposed control law, experimental results are given.
