Many of the tactical and political movements of recent years, even military movements that are underway at this time, have to do with the so -called rare earths, and these are in the hands of very few countries. It is not really called rare earths because they are not common, but because it is uncommon to find them purely.
This implies that those who have direct access to these deposits have great advantages, not only for their internal development, but to establish an enriching trade. The big problem in this regard is that the deposits are, as we said, in the hands of a few, mainly China, and therefore have a dominant position on the rest.
And what have to do with rare earths with electric motors?
That is the big question that many can ask, but that is answered in a simple way. From some of the elements called rare earths, magnets are generated, with which electric motors are then manufactured, in addition to other elements.
Therefore, a challenge is to create electric motors in which it is not necessary to use these rare earths that, in addition, have a great environmental impact both when extracting them and later when recycling the engines.
It is for this reason that Green Silence Group, an Italian consortium formed by the companies Settima Meccanica, Motive and Spin, is trying to revolutionize the sector eliminating rare earths, increasing efficiency and reducing costs.
For this they are developing synchronous engines that have already patented and that do not use rare materials or permanent magnets. Even so they achieve good energy performance, they say that superior and constant compared to current engines, and are also recyclable.
Thanks to this point, the cost is reduced by minimizing dependence on external materials, and is also a significant advance in environmental issues. The big difference is in the rotor design, as explained by Alessandro Tasi (spin CEO):
“In the Spinrel engine, instead of permanent magnets, we take advantage of the alternation between iron-sailor and air. We have optimized the shape of the rotor and its barriers, using the principle of resort“
As for applications, the potential of this type of engines could be raised, passing from the use in industrial and commercial vehicles to agricultural machinery, excavators, forklifts and even ultra -silent humanoid robots.
One more step in the world of electric mobility that continues to evolve.
