Any type of engine converts the incoming energy to move the vehicle. As a rule, it is quite energy efficient process, but even it can be improved. And if we take into account the fact that according to the statistics of the University of Chicago only in the US 50% of all energy is produced by engines, even a small improvement in the process will significantly save. And recently, scientists have developed special magnetic materials that will help in the creation of high-energy electric motors of the future.
In order to convert electrical energy into kinetic energy for motion, all processes occur under the influence of a magnetic field. But the higher the engine speed, the greater its temperature and in the end part of the energy is simply dissipated as heat.
But what if you make sure that the material is not heated? A group of scientists led by Michael MC Henry, Professor of materials science and engineering at Carnegie Mellon University, wants to solve this problem by synthesizing metallic amorphous nanocomposite materials (MANCs). It is a class of soft magnetic materials that are effective at converting energy at high frequencies, allowing for smaller engine sizes to provide comparable power to larger counterparts.
Currently, the motors are mainly made of steel and silicon. MANCs are an alternative to these materials and because of their high resistance they do not heat up so much and can rotate at a much higher speed.
“As a result, you can either reduce the size of the engine at a given power or make the engine a higher power at the same size.»
For the synthesis of MANC, scientists use liquid metal alloys that harden at extremely high temperatures. Due to this, the material gets new and unique properties.
