RESUMO

The main task of this work is to provide a contribution to help a more deep understanding on the operation of the asymmetrical twophase induction motor with return for applications in places where a possibility of a two-phase network feeding exists. important contributions where obtained with the help of a time domain dynamic model for symmetrical and asymmetrical two-phase machines developed as part of this work. With such contributions it was possible to show that a threephase induction motor can work as a two-phase asymmetrical induction motor with return through a phase or neutral conductor, without the need of some starting devices, such as, centrifugal switch and capacitors. this was proved through load and no-load tests and by way of comparisons between theoretical and experimental results. Hence, with such a work, we are seeking for the revitalization of the asymmetrical two-phase induction motor theory, a machine that presents a non-uniform magnetomotive force and electromagnetic torque.
