WebOct 16, 2024 · Now my topic: I am working on a specific shaped mu-metal shield, optimizing shape, thickness and material (B-H curves from different suppliers, all either loaded manually in FEMM or via Lua script). For the time being I want to benchmark the simulation with some lab measurements using permanent magnets of known grade, arranging them … WebJan 23, 2024 · Given the original curve spans the second quadrant, the curve should be translated along the H -axis by abs (Hc). When doing so, the input B-H curve will start at (0,0) and reach the remanent flux density Br at the value abs (Hc). Further instructions can be found in the AC/DC Module User’s Guide. c5系樹脂

WebThe objective of the analysis is to determine the flux density at the center of the iron bar, and to plot the field along the r=0 axis. This analysis defines a nonlinear B-H curve for the iron and employs an asymptotic boundary condition to approximate an "open“ boundary condition on the edge of the solution domain. AC conduction WebJun 14, 2008 · It probably needs adjustment, since FEM warns of accuracy errors if your B-H curve does not include your operating region. The next model should run some tests manually so the amount of saturation can … Web“Weird” B-H curves can result if you have entered too few points around relatively sudden changes in the B-H curve. Femm “takes care of” bad B-H data (i.e. B-H data that would result in a cubic spline fit that is not single-valued) by repeatedly smoothing the B-H data … dj juice mp3
