The efficiency of Hybrid Electric Vehicles (HEVs) may be substantially increased if the energy exhaust gases, which do not complete expansion inside cylinder internal combustion engine, is efficiently recovered by means a properly designed turbogenerator and employed for vehicle propulsion; previous studies, carried out same authors this work, showed potential hybrid fuel increment up to 15% em...

about internal defects within the insulation. The index k is defined as the proportionality constant between the changes at high voltage of capacitance ∆C and of the dissipation factor ∆tanδ . ∆C and ∆tanδ values were highly correlated when small flat defects were within the insulation and that correlation was lost in the presence of large narrow defects like electrical treeing. The discriminat...

In active magnetic bearing control systems, the performance of closed-loop and application can be impaired by external disturbances. This article analyzes unbalanced pull forces produced eccentricity a high-speed 1MW 3-phase solid rotor induction motor. The effect on five-degree-of-freedom resulting vibrations are studied. Finite-element-method-based modeling electrical machine is carried out, ...
