A method is proposed in this article to place sensors an electrical machine order be able reconstruct the magnetic field distribution. This based on empirical interpolation combined with Maxvol technique. The results applied a surface-mounted permanent magnet at no load show that distribution can accurately reconstructed even when sensor location imposed airgap of rotating machine.

Electrical characterization methods for the analysis of alternating current thinfilm electroluminescent (ACTFEL) devices are reviewed. Particular emphasis is devoted to electrical characterization techniques because ACTFEL devices are electro-optic display devices whose performance is to a large extent determined by their electrical properties. A systematic procedure for ACTFEL electrical asses...
