The three-phase induction motor was the fundamental component for productivity and growth in second industrial revolution Europe United States late nineteenth century. Presently, it is main charge electrical systems on a global level. In Brazil, reaches more than 65% of total electricity consumption. Policies were established minimum efficiency level to improve energy Brazilian system. legislation performance electric motors recent because first document issued 2002. Based policies improvement motors, what changes that occurred with squirrel-cage rotors marketed Brazil? Therefore, this study evaluated 435 tested between 2015 2016, powers 1 HP 250 four normalized speeds based three laws performance: Presidential Decree No. 4,508/2002; Interministerial Ordinance 553/2005 1/2017. All data collected via standardized laboratory tests accredited by National Institute Metrology, Standardization, Industrial Quality (INMETRO) International Laboratory Accreditation Cooperation (ILAC). results show 97% have higher performances 4,508/2002. Relatedly. 64% compared stipulated 553/2005. Also, only 21%
