摘要：Within the EMAD Research Center was initiated researches about CEUS figures obtained by exposing the content of a cylindrical container on the progressive action of the magnetic field produced by a special winding associated with GROSU stator. Inside the recipient was stored a quantity of ferrofluid which surface were scattered gold or bronze particles. The assembly thus obtained was studied using a suitable video camera, obtaining the so-called CEUS figures that constitute true stamps that highlight and identify the particularities of the studied types of electric drives.
