OPERATION OF INDUCTION MACHINE WITH SINGLE AND DOUBLE UNBALANCES

Abstract

Problem of unbalance opeiatton of induction manly has been of Mat interest to a large mbar of authors (1, 3, 4). Metho8 at symmetrical cnponont have been the def tool foa studying this problem. The unbalanced oration can be tThiided. into two a ri 5; (t) Sin& Unbalence $so* lapedanco unbalozee either sLde of aigap. (ii) Double Unbaluine i.e. .impedance unbalance on both amiss of air*gap* The principle of spec", scion always makes it possible to ezond the an2rsia of e above two categories of unbalance to the still more general case where stator voltage unbalance is also present siuttaneoua1y. For this reason the voltage unbalance has not been considered in separate category of unbalance.
