Influence of Unbalanced and Waveform Voltage on the PerformanceCharacteristics of Three-phase Induction Motors

Abstract

This paper examines the proper application ofthree-phase induction motors when supplied by unbalanced andharmonics voltage. The proposed is show that a poor powerquality voltage have bad effects over the motor performance:loss, temperature rise, rated horsepower, efficiency , magneticnoise and reliability. Finally this paper presentrecommendations in order to increase the reliability ofinductions motors operations.
