RESUMO

This dissertation has the aim of determining a mathematical model for asymmetrical two-phase induction motor with T-connected stator windings and to investigate some properties such as free acceleration, steady-state torque-speed characteristic and steady-state currents. This motor is designed to operate from supply of two phases and neutral, and a particular value for the stator tums ratio is required. First, a transformation of variables is accomplishedto obtain an equivalent motor that do not have electric connection and that presents the same m.m.f. of original motor. Making use of the concept couple circuits, the basic equations are derived. Second, these variables are written in the stationary referencefTameand an equivalentcircuit is obtained. By using this equivalent circuit, computer simulationis presented and compared with experimental results. The tests exhibited a good agreement, showing that the mathematical model is adequate
