Ixellion aims to develop and industrialize innovative electric
Motors/Generators based on proprietary technology and know how on Soft
Magnetic Composites.
World energy demand is continuously growing,
the resources in use today are mainly fossil fuels which are present in
limited quantities and are also responsible for harmful emissions into
the atmosphere.T
o ensure a balanced and lasting supply of energy
and to intervene to mitigate the processes of climate change in
progress, world governments and primarily the European Union, have
decided to intervene on the levels and methods of consumption of energy
resources with the aim of reducing 20% of energy consumption by 2020
compared to current ones.
In order to achieve this goal, one of
the ways to be pursued is the improvement of efficiency in energy end
uses of existing plants. Particular attention is paid to the analysis
and management of the consumption of electric motors which, within the
production cycles, are the largest users and therefore consumers of
electricity.
Savings can be obtained both by
modifying the energy processes so that there is less waste, and with
technologies that are able to transform energy from one form to another
in a more efficient way. In particular, electric motors absorb up to 74%
of the total electricity attributed to the sector

Hysteresis cycle
The energy supplied to the ferromagnetic core during the magnetization phase is not completely returned during the demagnetization phase; in consequence, part of the energy remains stored in the material.
The quantity is proportional to the area of the hysteresis cycle and depends on the type of material, the maximum induction value and the frequency of the magnetizing current.
A variable magnetic field created by an alternating electric current produces transient voltage gradients in a conductive magnetic material which in turn generate parasitic electric currents and are the cause of energy losses due to the dissipation of heat by electrical resistance. The induced currents are inversely proportional to the resistance of the material.
The most obvious solution to counteract leaks and improve the efficiency of electric motors is the application of soft magnetic materials based on Fe metal powders or Fe alloys and other components covered with a thin layer of electrically insulating phenolic resin which has the function of glue.
