Latest Technologies, Highest Quality
Aurora NEMA Premium Efficiency T-Frame Motors are three-phase induction, TEFC (Totally Enclosed Fan Cooled) squirrel-cage motors manufactured with the latest technologies. Our stator core is manufactured with high-quality laminated electrical steel. The high permeability and low loss of the steel enables Aurora frame motors to operate more efficiently.
Wide Range of Applications
The low-noise, low-vibration design of Aurora T-Frame Motors features advance cooling capabilities and makes these NEMA T-frame motors perfect for a variety of applications including compressors, ventilators, and pumps for petrochemical, medical, and mining environments.
