Solar Electric Motor on Superconducting Bearings in Liquid Nitrogen - Vertical Configuration - 190 rpm

<p>A solar electric motor, immersed in liquid nitrogen, and levitated on superconducting bearings, has been designed and tested at the GREEN Laboratory. This video shows the permanent regime that represents a speed around 190 rpm, with a configuration of superconducting bearings called "vertical configuration" and a Plexiglas cylinder around the cubic rotor in order to reduce the frictions in the liquid. It's the same rotor than in [10.5281/zenodo.154095] but the Plexiglas cover has been added, which leads to an increase of the speed from 75 rpm to 190 rpm.</p>
