Comparação do Impacto do 2° e 5° Harmônicos no Rendimento de Motores Elétricos de Indução Premium de 1CV

This paper presents a work that aims to evaluate the 2
^nd
-harmonic and 5
^th
-harmonic voltage impact on a Premium electric induction motor’s energy efficiency operating in under, over and at nominal loading condition. During the development of this work, it was performed several tests in a 1-CV Premium Electric motor that consisted in supplying a voltage containing a 2
^nd
and 5
^th
order harmonic to the electric motor operating in under, over and at the nominal loading condition. The results were statistically analyzed using simple linear regression models and depicted that 2
^nd
and 5
^th
harmonic greater reduced the motor’s energy efficiency when operating in overloading condition, with the 2
^nd
harmonic component provoking greater reductions on motor`s energy efficiency.
