Incidence of harmonic in asynchronous three-phase motors

The objective of this work is to analyze the incidence of the time superior harmonics over the characteristics of a motor behavior. For this purpose, a computer program in Matlab was made, and it was possible, for different voltage supply waves, by the Fourier Series Analysis, to find the incidence of each harmonic over the motor parameters. Besides this, the machine general behavior can be obtained when all the harmonics of the highest order are present applying the superposition method. The importance of this work is focusing firstly on the possibility to simulate the effect of each harmonic that is present in the wave that is analyzed over the motor behavior. In second term, from the didactic point of view because it allows to compare the machine characteristics over the influence of the different time harmonics. (C) 2011 Published by Elsevier Ltd.
