VOLTAGE VARIATION IN HIGH EFFICIENCY MOTORS: A TECHNICAL AND COMPUTATIONAL APPROACH
Keywords: Efficiency classes, temperature, voltage variation, line-start permanent magnet motor, genetic algorithms
AbstractVoltage variation is a silent enemy in electrical systems and with considerable effects on electric motors. In this work, technical experiments were carried out to evaluate the impact of this disturbance in electric motors classes IE2, IE3 and IE4, then computational simulations were carried out using genetic algorithms to predict the temperature of the analyzed motors. The results showed how the voltage variation produces deviations in consumption and temperature, while excellent temperature approximations were obtained by computational techniques.
