The paper presents a set of experimental investigations related to the study of the dynamic behavior of supercapacitors. The experimentally-inferred results are then used as inputs for an improved version of one of the most common supercapacitor RC-circuit ...
This paper presents a 3-D finite-element modal analysis to reduce the acoustical power radiated by a brushless permanent-magnet synchronous machines and avoid any resonance phenomena. The method is able to analyze the impact of some design parameters on al ...
This paper proposes a new experimental investigation of the ageing mechanisms of super capacitors. Starting from the main ageing mechanisms of these devices reported in the literature, the paper proposes a suitably developed procedure aimed at evaluating t ...
Industry applications involving torque brushless dc motors require high efficiency over a large speed range. In order to achieve such specifications, flux weakening is necessary, which could lead to relative high electromagnetically induced vibrations and ...
