A novel type of “bearingless” permanent magnet (PM) synchronous motor is presented. The motor consists of two conical air gap bearingless PM half-motors, mounted on a single shaft. Each conical stator houses two separate three-phase distributed AC windings with different magnetic pole pair counts. The motor winding has the same pole count as(More)
Gold (3 wt. %) catalysts on Y-doped (1, 2.5, 5 and 7.5 wt. % Y2O3) ceria supports prepared by coprecipitation (CP) or impregnation (IM) were studied in complete benzene oxidation (CBO). A low-extent Y modification was chosen to avoid ordering of oxygen vacancies. The samples were characterized by XRD, TGA, XPS and TPR techniques. A positive role of air(More)
