I componenti simmetrici ai valori istantanei per avvolgimenti lineari a guaina (Instantaneous Value Symmetrical Components for Linear Sheath Windings)

After a brief review of the expressions of the instantaneous value symmetrical components for discontinous and circular sheath windings, the extension of the application of the symmetrical components to linear sheath windings is presented. First of all it is shown that this problem arises when in the air gap the m. m. f. drops due to the unknown current density distribution in the linear sheath, the end effects of the linear induction motor are taken into account. The interest and usefulness of the results in the analysis and in the physical interpretation of end effects are then discussed.
