The majority of electric energy is transformed on mechanical energy by means of induction motors so little increasing of them efficiency give big savings in scale of country and decreasing of exploatation costs. Considerable part of these motors often works in variable loading less nominal and them efficiency is smaller in these conditions. Computers calculations showed that choosed value of motors voltage in loading less then rated so it is possible to increase of efficiency even about several points of percent. For to confirm the results of calculation are made the measures of energy received from the mains for variable conditions of loading and suppling of motors frame number 132. The results of tests do not confirme the results of calculations. The efficiency of induction motors increases with voltage increasing just in loading less then 20% rated load and consumption of electrical energy deacreases but economical effect is discussional.
