This non-oriented fully processed high frequency grade has guaranteed magnetic properties in accordance with EN 10303:2015, which specifically concerns thin electrical steels for use at frequencies above 100 Hz. Full magnetic characterisation curves at various frequencies are available on request.
High frequency electrical steels have very low loss levels, especially at high frequencies. These properties are a result of the thin gauge of this material (0.20 mm), its particular chemical composition and specific thermomechanical processing.
This grade is designed for high speed rotating machines (100 to 5000 Hz). It allows minimisation of losses due to higher harmonics and clearly increases machine efficiency in the case of non-sinusoidal power supply. This thin, fully processed grade is also used when weight and volume reduction are of major importance, such as in medical or aviation applications.
Recommendations for use
The above properties are obtained without heat treatment after stamping. The material as supplied possesses all the required magnetic properties.
