    摘要： A system is provided for transmitting control signals to the internal devices of a compressor. The compressor includes a housing, a hermetic power terminal and a motor for powering the compressor. The system includes a frequency converter that is located external to the compressor housing and a frequency decoder that is positioned inside the compressor housing. The frequency converter can convert a control signal from a controller to a high frequency signal. The frequency decoder decodes and converts the high frequency signal to a control signal for an internal device of the compressor. An AC input power source provides electrical power to the motor, and power transmission lines connect the AC input power source to the hermetic power terminal. The frequency converter is electrically coupled to the frequency decoder by two power transmission lines.

    摘要： A system and method is provided for controlling the speed of the compressor to ensure adequate lubrication oil is provided to the components of the compressor. During operation of a capacity control program for the compressor, a preselected operating parameter of the compressor or motor drive is measured. The measured preselected operating parameter is compared to a preselected range for the operating parameter. If the measured preselected operating parameter is not within the preselected range, the output frequency of the capacity control program can be increased to provide proper lubrication for the components of the compressor.

    摘要： A heater is provided inside a hermetic compressor to heat the fluid in an oil sump of the compressor. The heater can be substantially submerged in the fluid even at low fluid levels. The heater can raise the temperature of the fluid to a predetermined temperature to substantially maintain non-lubricant fluids in a gaseous state and prevent non-lubricant fluids from mixing with the lubricant in the sump. A feed through assembly in the compressor housing is used to supply power to both the compressor motor and the heater.
