Abstract: A system includes a refrigerant compressor including an electric motor, a current sensor that measures current flow to the electric motor, a switching device configured to close and open to allow and prevent current flow to the electric motor, respectively, a maximum continuous current (MCC) device that includes a resistance corresponding to a maximum continuous current for the electric motor, and a motor protection module. The motor protection module communicates with the MCC device, the current sensor, and the switching device and determines a first MCC value for the electric motor as a function of the resistance of the MCC device. The motor protection module also selectively sets a predetermined MCC to the first MCC and controls the switching device based on a comparison of the current flow to the electric motor and the predetermined MCC.

Abstract: A refrigerant compressor includes an electric motor. A current sensor measures current to the electric motor. A switching device is configured to close and open to allow and prevent current flow to the electric motor, respectively. A maximum continuous current (MCC) device generates an output that one of: (i) is an MCC for the electric motor and (ii) is a value indicative of the MCC for the electric motor. A motor protection module: is remote from the MCC device; receives the output wirelessly from the MCC device via an antenna; one of sets a first MCC to the MCC for the electric motor and determines the first MCC based on the value indicative of the MCC for the electric motor; selectively sets a predetermined MCC to the first MCC; and controls the switching device based on a comparison of the current to the electric motor and the predetermined MCC.

Abstract: An apparatus is provided and may include a compression mechanism, a valve plate having a plurality of ports, a header, and a plurality of cylinders disposed within the header. A plurality of pistons may be respectively disposed in the plurality of cylinders and may be movable between a first position separated from the valve plate and permitting flow through the plurality of ports and into the compression mechanism and a second position engaging the valve plate and restricting flow through the plurality of ports and into the compression mechanism. A chamber may be disposed within each of the cylinders and may receive a pressurized fluid in a first mode to move the piston into the second position and may vent the pressurized fluid in a second mode to move the piston into the first position. One of the chambers may include a different diameter than the other of the chambers.
