Implementação de uma ferramenta computacional para obtenção das características de funcionamento de motores de indução

Abstract

This work presents a computational tool able to plot the induction motor´s characteristic curves and calculate stator current, power factor, induced torque, converted power and maximum torque for any load condition, from the collected data with the locked rotor test and no-load test. Such tool can assist electrical engineering students or technicians in analyzing induction motor´s performance by comparing characteristics obtained with this tool and the data provided by manufacturers in their catalogs. In that way, students and professors may use it in practical classes on induction motor and exercises. Also, in situations where motor´s performance is needed to be evaluated due to time or bad operation, and it is not possible to be done with visual inspection, the present tool could be useful.
