Digital Simulation of Three-Phase Induction Motors

The problem of solving the general three-phase induction motor performance equations is discussed and methods of digital solution for both the three-phase motor and the two-axis model are described.

Analysis of Balanced Three-Phase Induction Motor Performance under Unbalanced Supply using Simulation and Experimental Results

Induction motors are known to affect the electrical power system in terms of harmonics. Induction motors fed by unbalanced power systems produce additional current harmonics. These harmonics cause additional power losses in the machine. The method of symmetrical components is often used in this kind of unbalanced operation analysis. In this study, the performance of a three phase induction motor supplied by unbalanced power system due to the various causes has been examined using both experimental method and Matlab/Simulink model.

The zero-sequence parameters and performance of three-phase induction motors

The authors have already demonstrated1 that zero-sequence currents can produce a finite torque in a 3-phase induction motor, and that it is the predominant component torque in certain cases of asymmetrical connection. The present paper shows, for the first time, how the relevant parameters for zero-sequence operation may be determined from certain test results, and how they may be utilized to predict the performance of the machine when zero-sequence voltages only are applied to the primary winding.It is suggested that the considerable torque available may find useful application in providing a speed reduction of 67% for brief periods of operation.
