摘要： In an operation control apparatus and a method thereof, the compressor can be protected from overloading through a current control device instead of an OLP (Over Load Protector) and a PTC thermistor (Positive Temperature Coefficient thermistor). The operation control apparatus includes: a stroke estimated unit for estimating a stroke of the compressor on the basis of a current and a voltage applied to an interior motor of the compressor and a motor constant of the interior motor; a control unit for generating a control signal for varying a stroke of the compressor on the basis of the estimated stroke value and a preset stroke reference value; and a current control means being turned on/off so as to vary a stroke voltage applied to the interior motor of the compressor.

摘要： In an overload protective apparatus of a compressor and its method capable of preventing damage of a compressor due to overload by removing an overload protector and using an operation control device operating the compressor, the overload protective apparatus includes a reference current setting unit for presetting a reference current value for operating the compressor normally; a microcomputer for generating a power cutoff signal when the detected current value is greater than the reference current value and generating a power supply signal when the detected current value is smaller than the reference current value; and a power supply unit for cutting off power applied to the compressor on the basis of the power cutoff signal or applying power to the compressor on the basis of the power supply signal.
