A family of 5 to 200 HP high-speed permanent magnet or induction motors with operational speeds ranging up to 180,000 rpm has been developed. Each motor uses MiTi® airfoil bearings, high power density motor elements and a VFD to provide motors with efficiencies greater than 95%. Because MiTi® oil-free airfoil bearings are used, no auxiliary lubrication supply system is needed, eliminating maintenance and hazardous waste disposal issues. Efficiency gains of from 30-35% over medium sized, high-speed motors using oil-lubricated bearings have been demonstrated. The VFD permits a wide operating speed range and precise speed control. As with our other products, the single moving part and MiTi® bearings assure long life and low maintenance in a compact package. Custom designs requiring higher power levels and speeds to meet special needs are available.
