A disc-type rotor magnetic bearing with 3-pole magnet is considered in the paper. The supported by electro-magnetic forces has potential industrial application especially flywheel energy storage systems. However, coupling phenomenon acting makes balancing control problem system challenging. Based on analysing rotor, mechanism identified, and a coordinate transformation formulated to decouple fo...

The active magnetic bearing (AMB) is an integral part of the industrial rotational machine. The paper deals with simulation study of three and four coil AMB utilizing Finite Element Method (FEM). This paper also presents how ANSYS software (Ver. 12.1) can be used to perform the magnetic field analysis in the AMB. This work reports ANSYS simulation for two different structure of AMB that uses th...

Abstract: This paper proposes a five-degree-of-freedom (5-DOF) hybrid magnetic bearing (HMB) for direct-drive wind turbines, which can realize suspension in the 4-DOF radial and 1-DOF axial directions. Only two sets of radial control windings are employed in the proposed HMB because only one set of radial control windings can achieve the 2-DOF suspension in the radial direction. Unlike the trad...

Herein, we present a water dispersable, magnetic nanoparticle supported "click and release" system. The cleavable linker has been synthesized by using a strain-promoted copper-free "click" reagent to establish the specific link and a fluoride cleavable silane moiety for mild cleavage. Small organic molecules, azide-bearing dyes and functionalized enzymes have been bound to the magnetic particle...
