Speed Variation of a Cage Induction Motor under Square Voltage Modulation

Scientific Journal of Gdynia Maritime University
Cyclic voltage fluctuations can be considered as a superposition of the fundamental voltage component, subharmonic and interharmonic components – that is the components of frequency less than the fundamental one or not being its integer multiple.
