• A single-sheet tester to measure electrical steel loss under uniaxial magnetisation. Transverse magnetisation is shown occur in grain-oriented silicon steel. Losses due transverse fields are not detected conventional test methods. losses depend on grain size and mis- orientation oriented normally of practical importance machine cores. modified rotational tester, which a circular sample can be...

We present the first investigation of electrical corrosion in acupuncture needles after electrical stimulation. Using scanning electron microscopy, we observed the occurrence of electrochemical corrosion on the surface of stainless steel 304 acupuncture needles after electrical stimulation in the tibial muscles of rats. Biphasic pulse electrical stimuli with 10-Hz frequency, 1-mA intensity and ...

This paper deals with characteristics of interior permanent magnet synchronous motor considering anisotropic characteristics of electrical steel sheets. Motor characteristics of back electro-motive force (EMF), d-q axis inductances, and core loss are calculated by FEA considering anisotropy of electrical steel sheets and compared to the results from experiment and general FEA; using single mate...

The performance of vibration power generation using the inverse magnetostrictive effect increases with increasing its device size. In this study, grain-oriented electrical steel that can be largely produced was investigated as a core material, U-shaped unimorph at laboratory scale. (16 mm long 1.4 mm2 cross-section) rolling direction (RD) along stress exhibited effective open-circuit voltage 0....
