Estudo comparativo sobre desempenho e operação entre uma máquina de indução trifásica e uma máquina de indução bifásica com mesmas características construtivas.

Abstract

This paper investigates the two-phase and three-phase induction motors with the same structural characteristics.The two-phase motor was originally a three-phase induction motors and was rewind. The paper also presents comparer the two motors about engineering aspects in terms of performance and operation.In chapter two the machines’ FMM are presented and compared. In chapter three a dynamic model for the open-end winding symmetrical two-phase induction machine is developed, as well as a bibliographic review of the dynamic model of the three-phase symmetrical induction machine. The equivalent circuit for the machines is described in chapter four. The tests in laboratory will represent real industrial mechanical loads and will be discussed in chapter five. In chapter six experimental data and simulations are presented as a comparison tool to qualify the machines for the transient regime and permanent regime.
