Voltage quality of power supply for three-phased induction motors is defined with value of voltage, voltage asymmetry and harmonic distortion of voltage. In this paper, an influence of voltage quality on energy efficiency of three-phased induction motors has been pointed, with particular review on energy efficiency of induction motors with squirrel-cage rotors in agriculture. Increase of energy efficiency of induction motors is achieved not only with applying energy efficient induction motors, but also with optimization of costs of consumed electrical energy, on which significantly influences the quality of voltage power supply and the choice of optimal value of voltage power supply, considering nominal power, working mode, load and constructive characteristics of induction motors being applied.
