This paper describes how to extract the fundamental-frequency components from the voltage and current waveforms in a split-phase induction motors that is fed through a static voltage controller. These components are derived not from conducting a fast Fourier transform, but rather from few phase angles that are easily provided by zero-crossing and peak detectors. It is shown that knowledge of these...
Before arbitrarily selecting a conventional electromechanical motor starter, solid-state energy-saver starters should be evaluated. With the ever-increasing cost of electrical energy, conventional starters, and downtime, solid-state starters are becoming practical and cost effective in the 50-400-hp range.
