Abstract

The results of a study on electrical characteristics of hermetic compressor motors used in domestic refrigerators are described. The voltage and current waveforms during start and run states have been investigated for sinusoidal, near square wave and near triangular wave input voltages in the range 170-260V. An instrumentation system based on an ADC/DAC plug-in card in a personal computer is developed for this purpose. It is deduced that through a considerable redesign of the windings the optimal point of operation corresponding to nominal supply voltage and an improvement in the power factor can be achieved.
