Relative Permeability Of Steel Laminations

This product group consists primarily of 006 029 low carbon and silicon alloy steels.

Relative permeability of steel laminations.

Our average lead times on new tooling range from 10 12 weeks. A magnetic core is a piece of magnetic material with a high magnetic permeability used to confine and guide magnetic fields in electrical electromechanical and magnetic devices such as electromagnets transformers electric motors generators inductors magnetic recording heads and magnetic assemblies it is made of ferromagnetic metal such as iron or ferrimagnetic compounds such as ferrites. Small hysteresis area resulting in low power loss per cycle low core loss and high permeability. There are two types of electrical steels used for rotor laminations semi processed and fully processed.

Our high speed tooling offers a low cost alternative to maufacturers with moderate to high volume stamping requirements. Both are non oriented steel grades. Electrical steel lamination steel silicon electrical steel silicon steel relay steel transformer steel is an iron alloy tailored to produce specific magnetic properties. The corresponding degradation for laser cut laminations is 65 iron loss density increase and 65 per meability drop.

More detailed information about these two types of steels can be found in the metals handbook. The magnetic properties namely the iron losses and the relative permeability of sife electrical steel laminations after mechanical and laser cutting are studied. Steel cores or laminations can usually be removed from the protective atmosphere at 600 700 f 325 375 c without ill effect. Electrical steel is usually manufactured in cold rolled strips less than 2 mm thick.

Material of lower thickness but with the same si content shows lower. It has been used primarily for transformer cores magnetic shielding ground fault circuit interrupters tape wound toroids and laminations operating at very low magnetic. Laminations mechanical cutting causes up to 35 higher iron loss density and 63 lower permeability compared to standard epstein strips 30 mm wide. Small hysteresis area resulting in low power loss per cycle low core loss and high permeability.

Cartech hymu 80 alloy is a nonoriented 80 nickel iron molybdenum alloy with extremely high initial permeability and maximum permeability with minimum hysteresis loss. Custom steel laminations represent over 50 of all sko die stampings. Mechanical cutting with guillotine shears and cutting by means of fiber and co2 lasers are considered. The magnetic measurements are conducted on the epstein frame for frequencies of 50 100 and 200 hz.
