MiTi - Motors

MiTi has developed a family of 5 to 200 HP high-speed permanent magnet or induction motors with operational speeds ranging up to 180,000 rpm. 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.
