Energy efficiency of induction motors in agriculture

Abstract

The paper points to some possibilities for increasing the energy efficiency of asynchronous electric motors with special emphasis on the use and energy efficiency in agricultural production. The most important measures in this regard should be taken are: the application of energy-efficient induction motors, selection of motors based on electric power, replacing the old motors with low level of efficiency, setting the value of supply voltage, reactive power compensation and optimization of regulated electric drives with induction motors.

U radu je ukazano na neke mogućnosti povećanja energetske efikasnosti asinhronih električnih motora sa posebnim osvrtom na primenu i energetsku efikasnost u oblasti poljoprivredne proizvodnje. Najvažnije mere koje u tom smislu treba preduzeti su: primena energetski efikasnih asinhronih motora, pravilan izbor motora po snazi, zamena starih motora niskog stepena korisnog dejstva, podešavanje vrednosti napona napajanja, kompenzacija reaktivne energije i optimizacija regulisanih elektromotornih pogona sa asinhronim motorima.
