Computer-aided Magnetic Field Analysis Using the Boundary Element Method

Efficient design of electromagnetic devices requires the analysis of electric and magnetic field distributions. To this end, the boundary element method (BEM) has been shown to be a powerful technique. This paper presents the use of BEM in computer-aided magnetic field analysis. The advantages of BEM over the finite element method (FEM) are stated. The recent introduction of BEM in a generalize...

Active Magnetic Bearings (amb)

A magnetic bearing is a bearing which supports a load using magnetic levitation. Magnetic bearings support moving machinery without physical contact, for example, they can levitate a rotating shaft and permit relative motion without friction or wear. In active magnetic bearings (AMB) a stable equilibrium is achieved by means of one or more control loops. The use of control loop for maintaining ...
