Feasibility of Wheel-Based Magnetostrictive Energy Harvester

Park Y.W., Wereley N.M., Park Y.W., Chungnam National University, KR

Manually-pushed carts with rotating wheels are easily seen around us. Also, active RFID has been gaining ground toward commercial usage. Currently possible power supply may be a rechargeable or disposable battery for the reader. The [...]

Modeling and Simulation of a Permanent Magnet Array in Elliptical Configurations

Lee S.J., Jiles D.C., Iowa State University, US

Permanent magnet arrays have advantages for magnetic field generation over the traditional current based magnetic flux sources, such as electromagnets, in that they do not require a power supply and cooling system. Magnetic flux density [...]

Semianalytic Modelling of a Magnetic Levitated Disk with Nonuniform Polarization

Michael S., Scheinert G., Uhlman H., Technical University of Ilmenau, DE

A magnetic bearing for a high rotating electromagnetic drived disk with regard to future applications like the Laser-TV is modelled and designed. For modelling of the system consisting of permanent magnets and copper coils a [...]
