Totally Enclosed Fan Cooled Induction Motors

Product Detail Information

Totally enclosed fan cooled Induction motors

3000V, 6000V CLASS 37 TO 2000kW

HIEGN Induction Motor Types FE and HE feature tough and sturdy construction. These motors employ class F insulation and their dimensions comply with IEC Standards.
A cooling fan, mounted on rotor shaft at end opposite the drive end assures efficient ventilation.
They are easily inspected and maintained, and moisture. Low output motors are provided as CastIron Frame Motors and high output motors, as Sheet Steel Frame Motors.
