However, the values reported are often different from the measured values. Thus, this work presents the results obtained from testing 435 Three-phase Induction Electric Motors with Squirrel Cage Rotor from 38 different manufacturers tested between 2015 and 2016. The data were collected through standardized tests performed at the Laboratory of Electrical Machines of the Institute of Energy and Environment of the University of Sao Paulo. The values reported by the manufacturers were compared with the values measured in the laboratory. The results indicate that 58% of the values measured for the power factor of the motors were lower than those reported by the manufacturer. Similarly, 55% of the measured values for the performance were lower than the values reported by the manufacturer.</p> ER -
