| Summary: | The article presents the results of mathematical modeling of
induction motors powered by frequency converters taking
into account slot harmonics of EMF and stator current due to
corresponding pulsation of magnetic field induction in air gap. The
results of calculations for low, medium and high-power engines
are presented. It is shown that the spectrum-current analysis
method can be used to determine rotation speed of induction
machines when they are tested by the mutual load method using
various schemes. The method for determining the intervals for
searching for slot harmonics is proposed. |
