FEMLab software applied to Active Magnetic Bearing analysis

Adam Piłat (2004)

International Journal of Applied Mathematics and Computer Science

Similarity:

This paper presents how the FEMLab package can be used to perform the magnetic field analysis in the Active Magnetic Bearing (AMB). The AMB is an integral part of the industrial rotational machine laboratory model. The electromagnetic field distribution and density analysis allow verifying the designed AMB and the influence of the shaft and coil current changes on the bearing parameters.

Numerical approximation of self-consistent Vlasov models for low-frequency electromagnetic phenomena

Nicolas Besse, Norbert J. mauser, Eric Sonnendrücker (2007)

We present a new numerical method to solve the Vlasov-Darwin and Vlasov-Poisswell systems which are approximations of the Vlasov-Maxwell equation in the asymptotic limit of the infinite speed of light. These systems model low-frequency electromagnetic phenomena in plasmas, and thus "light waves" are somewhat supressed, which in turn allows thenumerical discretization to dispense with the Courant-Friedrichs-Lewy condition on the time step. We construct a numerical scheme based on semi-Lagrangian...
