The fourth revolution of the industry is powered by a wide
range breakthrough, new technology, innovative ideas
and creative activities. All these things were naturally born,
mostly, by the interdisciplinary science and technology. Soft
magnetic composites are the bright example of the different
technologies integration to get final commercial products
with enhanced properties. In the report we systematized
the methods, technologies and structures of this type of
heterogeneous materials with soft magnetic properties,
pros and cons are discussed. The main mechanisms of
magnetization reversal of such structures are reviewed, as
well as the effect of inhomogeneities on the main magnetic
properties: magnetic induction, permeability, coercive force,
and loss. The basic requirements to these materials for
practical use in advanced electric machines, electric vehicle
motors, electromagnetic micromotors and generators,
magnetic memory, and MEMS are analyzed.
We developed the technology of iron powder treatment to
create the nanometer coating on the surface of each particle.
The final magnetic details are produced by technology of
powder metallurgy. Unique specific parameters of a soft
magnetic composite material were achieved: magnetic
induction of saturation – 2.1 Т, working frequency range - up
to 1MHz, permeability – up to 1000, total loss – 8W/kg, Curie
temperature - above 800С. These allow to produce machines
with the large number of poles and high frequency of
switching, thus improving specific mass and size parameters.
LIGA-likeMEMS technology was developed to produce hybrid
stepper micromotor based on soft magnetic composites.
