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 T-Frame Motors to operate more efficiently.

Wide Range of Applications

The low-noise, low-vibrations design of Aurora T-Frame Motors features advance cooling capabilities and makes them perfect for a variety of applications including compressors, ventilators, and pumps for petrochemical, medical, and mining environments.
