Abstract: A system and method of sizing an inner diameter (604) of the center bore (104) of a laminated rotor (300) is provided. The inner diameter d of the center bore (104) is determined by taking a series of measurements in the center bore (104) with an electronic gauge (710) and then analyzing the measurements to determine the acceptability of the rotor (300). The electronic gauge (710) is inserted into the center bore (104) of the rotor (300) and measurements of the inner diameter d of the center bore (104) are taken at a variety of different depths and positions using the electronic gauge (710). The measurements are then analyzed to determine if the rotor (300) is acceptable for use by evaluating the measurements with respect to a reference diameter and a depth in the center bore (104).

Abstract: A two stage reciprocating compressor and associated HVAC systems and methods are disclosed. The reciprocating compressor includes a crankshaft having an eccentric crankpin, a reversible motor for rotating the crankshaft in a forward and a reverse direction, and an eccentric, two position cam rotatably mounted over the crankpin. The crankshaft and cam combine to cause the piston to have a first stroke when the motor operates in the forward direction and a second stroke when the motor operates in the reverse direction. The cam and crankpin also include stabilization means to restrict the relative rotation of the cam about the crankpin. A lubrication system is provided to lubricate the engaging surfaces of the crankshaft and cam and between the cam and the bearing surface of the connecting rod. There is also provided a control for selectively operating the motor either in the forward direction at a first power load or in the reverse direction at a reduced second power load. A protector for the motor is also provided. In addition, the application of the reciprocating compressor to both air conditioning and heat pump systems is disclosed.

Abstract: A pressure equalization system is provided for starting a compressor while maintaining the condenser at a high pressure and includes a valve and a bleed port. The compressor has a compressor inlet for receiving a fluid at a first pressure and a compressor outlet for discharging the fluid at a second pressure. The valve is proximate to and in fluid communication with the outlet and is movable to an open position when the compressor is operating to permit the fluid at the second pressure to flow through the valve and is movable to a closed position when the compressor stops operating to prevent backflow of the fluid at the second pressure through the valve toward the inlet. The bleed port is upstream of the valve and in fluid communication with the inlet to equalize the pressure of the fluid contained in the compressor when the compressor stops operating.

Abstract: A method of attaching a rotor to a shaft is provided to obtain increased motor performance. The increased motor performance is obtained as a result of a high impedance gap that is formed between the rotor bars and the rotor core during the heat shrinking operation to attach the rotor to a shaft. In the heat shrinking operation, the rotor is heated to between 600-800 °F. At this temperature the aluminum in the rotor bars expands faster than the steel in the rotor core and causes a deforming or yielding of one or both of the materials. As a result of this deformation of the material, the cooling of the rotor results in the formation of a gap between the rotor bars and the rotor core that operates as a high impedance barrier between the rotor bars and rotor core.
