MagWeb database is a compilation of 1267 digital B-H Curves and core loss curves of almost all known soft magnetic materials. The database covers a broad range of permeability from 10 to 10,000. High permeability magnetic materials such as Electrical Steel, Metglas are mostly available as thin lamination sheet. Medium permeability materials such as mild steel, stainless steel and casting are available as machinable bulk solids such as round, wire, bar, slab or plate. Low permeability materials such as powder cores are available as nonmachinable solids. BHmag database presents magnetic properties of all these materials. So it is useful in the design of diverse electrical equipment such as electric motors, wind generators, transformers, solenoids, inductors, relays etc.
MagWeb database lists the Magnetization curve, Permeability curve and Core Loss Curves of almost all soft magnetic materials. Each file contains tabulated data and B(H) curve or Core Loss curve. The data preserve the nonlinearity inherent in the B(H) curves. It also lists the manufacturer, thickness and frequency and the annealing condition at which the magnetization curve is measured.
1.1 MagWeb Folders
The MagWeb database contains 12 folders. Each folder refers to a specific material category. Each folder contains a digitial B-H Curve or core loss curve and lists a table of values of specific points on the curve.
|Category||MagWeb Folder||B(H) Curves||Core Loss Curves||Total Files|
|A||Electrical Steel – Non Grain Oriented||293||116||409|
|B||Electrical Steel – Grain Oriented||141||134||275|
|C||Metglas & Nanocrystalline||23||10||33|
|G||Low Carbon Steel||89||1||90|
|I||Iron Powder Core||49||26||75|
|J||Alloy Powder Core||28||43||71|
|Total Files in MagWeb Database||829||438||1267|
The user can easily integrate the database into any commercial software used to design Electric Machines.. Such integration relieves the designer the burden of selecting a trial magnetic material, collecting B-H curves, normalizing them into standard units, digitizing them and manually entering the data into the software, designing the electric machine and repeating the tedious process with another material. A design software with built-in MagWeb database can be used to quickly run the “what-if” simulations to analyze how change of materials affects the performance of machines. With few clicks, the designer can change a magnetic material and evaluate the impact of changed material on the performance. Such fast what-if simulations greatly reduce the time for selection of optimal magnetic materials, significantly reducing the design cycle time.
1.2 User Manual
MagWeb database is supplied with a comprehensive User Manual when the digital curves are purchased online. The user manual contains more detailed information on the database format, magnetic saturation and quality of digitization and other useful information.
