TEFC Enclosures

TEFC inverter-duty vertical pump motors

Aurora Totally Enclosed Fan Cooled (TEFC) Vertical Pump Motors are rapidly becoming the most recognized brand in the industry. Our robust motors perform under the most strenuous and extreme conditions and are built from the highest quality materials.

Standing up to the environment

Each component that goes into an Aurora motor is built to exceed your expectations. For example, the insulation system is designed to withstand a wide range of environmental conditions, thermal shock, and voltage stress. Windings are double vacuum-pressure impregnated (VPI) with a non-water-absorbent epoxy varnish for maximum protection. Tropicalization varnish is applied to motors used in coastal areas, mining applications, and in locations with high humidity or hazardous particles.
