High Permeability Electrical Steels

Cogent Power continues to develop new products tailored to deliver benefits in performance for bespoke applications.  Cogent offers a range of high permeability non-oriented grades which offer comparable loss performance coupled with a guaranteed minimum permeability. These grades of material offer finished motor designs improved torque as the electrical steel is easier to magnetise due to the higher permeability of the steel.

The magnetic characteristics of the steel originate from silicon hot rolled coil feedstock which can then heat treated  and cold rolled to give outstanding thickness control.

High Strength Electrical Steels

Cogent recognises that new motor designs continue to ask for improved performance parameters from materials and for fast rotating machines, and in particular for rotors with “very narrow” load bearing parts (e.g. internal permanent magnet rotors), the strength of the material is an important factor.

Cogent offer a number of grades with guaranteed mechanical strength levels.

In addition to our service offerings we can offer guaranteed mechanical properties combined with detailed fatigue and durability analyses.
