Abstract
In this paper, the equivalent circuit model of a three-phase induction motor with balanced nonsinusoidal voltage waveform is solved by the experimental test of a 3-phase, 3-hp induction motor with a variable voltage, variable frequency (VVVF) voltage source. The parameters are calculated by analyzing the test results with statistical methods.
The performance of an induction motor with nonsinusoidal voltage source is calculated by the computer simulation based on the circuit model derived. The simulation results are compared with the laboratory test to verify the accuracy of the equivalent circuit model.
