Desenvolvimento de plataforma experimental para o estudo do desempenho dinâmico da máquina assíncrona operando em velocidade variável para aplicação em tração elétrica

Abstract

This work contributes to the implementation and structuring of atests bench with three-phase induction motors, observing the recommendations of NBR 17190-3 standardof the Brazilian Association of Technical Standards (ABNT). The platform hasresistant andadjustable base, allowing to be studied motors until 10cv, with different types of motor housing. Tests base do ntechnical standards attestto the verification of the state of the motorin terms of efficiency, as well as assisting in the identification and correction of possible electrical and mechanical problems. The acquisition and monitoring data such as voltage, current, power, speed, torque, and others, is made with precision and reliability, and with safety for people and equipment guarantee. The operating principle and main characteristics of three-phase induction motors are discussed, as well as the presentation of the elements of the testbench. The out come of the work goes through the details of the tests performed as well as the analysis of the results obtained.
