StarRotor has a 3,200 sq. ft. facility with a temperature-controlled machining environment and supporting metal welding/fabrication shop. Our current milling capability allows the manufacture of rotors as large as 17 inches in diameter to accuracies better than 60 millionths of an inch (linear scale feedback). Six workstation computers host commercial software including Inventor (3-D solid modeling), Algor (FEA analysis of stress, deflection, heat transfer, and fluid flow), and FeatureCAM (computer-aided manufacturing). Proprietary software is used to determine gerotor geometry, efficiency, and bearing loads. Compressor designs are evaluated on a fully instrumented test stand equipped with a 100-kW, 10,000-rpm, variable-speed electric motor, appropriate sensors (speed, torque, temperature, pressure, vibration, and mass flow) and a LabWindows CVI-based data acquisition system.
