Towards practical quantification of induction drives mixed eccentricity

As far as industrial applications of induction drives are concerned, one of the most critical issues is the statement of acceptable mixed eccentricity degree and of other mechanical abnormal conditions. These troubles cause characteristic spectral components in many drive quantities, but for economic reasons the electrical quantities, already sensed for drive control purposes, are preferable; among them current signals (i.e. MCSA) are the electric signals of choice to detect the machine conditions.
