Patent ID: 8287245

Claim:
A system for transmitting control signals to internal components of a compressor, wherein the compressor comprises a hermetically sealed housing and a motor positioned inside the hermetically sealed housing, the system comprising: a first signal converter located external to the hermetically sealed housing, the first signal converter being configured to receive a control signal and convert the control signal to an output signal; a second signal converter located internal to the hermetically sealed housing, the second signal converter being configured to decode the output signal and generate a control signal for an internal component of the compressor; a power terminal configured and positioned to provide a hermetically sealed electrical connection through the housing; a plurality of power lines connectable to a power source to provide an operating voltage to the motor, the plurality of power lines connected to the power terminal external to the hermetically sealed housing; a plurality of motor leads positioned inside the hermetically sealed housing, the plurality of motor leads connected to the power terminal at one end and to the motor at an opposite end; the first signal converter is electrically coupled to at least one power line of the plurality of power lines to transmit the output signal through the at least one power line and the power terminal to the plurality of motor leads; and the second signal converter is electrically coupled to at least one motor lead of the plurality of motor leads to receive the output signal and the at least one motor lead is connected to the power terminal at a location corresponding to the connection of the at least one power line of the plurality of power lines to the power terminal.
