Electrical steel strips for generators, motors and static machines
isovac® is the non-grain-oriented electrical steel made by voestalpine, a cold-rolled steel strip made of iron-silicon alloys with special magnetic, mechanical and physical properties. These properties are crucial to a wide variety of applications, such as transformers, motors and generators. Such properties determine how economically energy resources can be used and ultimately the attractiveness of end products on the market.

Where isovac® is used
All motors, generators and static machine have one thing in common in that they have a core made of iron that generally consists of stacked laminations.
The primary areas of application are these:
- Systems dedicated to the generation of power: Creation of electricity in generators
- Power transmission and distribution Transformers
- Utilization of electrical energy by consumers: Motors

Worth knowing: grain-oriented and non-grain-oriented electrical steels
Significant differences appear in the magnetic properties of grain-oriented electrical steels between structures in the direction of rolling (very good characteristics) and structures crosswise to the direction of stock flow (poor characteristics). Processing steps must be selected to achieve favorable properties (direction of rolling).
Differences in the magnetic properties of non-grain-oriented electrical steels can occur, but they are substantially less pronounced. The material is characterized by low directionality (anisotropy) with respect to the magnetic and mechanical properties. The main applications for non-grain oriented electrical steel are motors of all sizes, generators, ballasts and much more.
Non-grain-oriented electrical steels are further differentiated as fully processed or semi-processed. The difference between these two types of electrical steel lies in the final manufacturing step.
