Nidec Now to Offer Stocked Inverter Duty Vertical TEFC Motors

OCT 02, 2017

ST. LOUIS –  October 2, 2017 – To respond to the growing demand for variable speed motors in municipal and industrial applications, Nidec Motor Corporation is adding U.S. Motors® brand vertical totally enclosed fan cooled (TEFC) inverter duty motors to its stocked offerings.

The use of inverters (variable frequency drives) in water/waster pumping applications has increased dramatically over the past few years in the quest for energy savings, process optimization and improved system reliability. 

Nidec has always, and will continue to, engineer inverter duty motors to meet individual customer specifications, but its new offerings will provide smaller municipalities and industrial customers the ability to purchase off-the-shelf product that meets their needs.

These vertical HOLLOSHAFT® high thrust motors for use on turbine, mix flow and propeller pumps range from 5 HP to 300 HP, and are suitable for variable frequency drive (VFD) operation per NEMA standards.

The HOLLOSHAFT® motor was developed to meet the specific needs of the vertical turbine pump industry. The pump shaft is extended through the hollow shaft, so adjustments required to lift impellers and give a running clearance with the pump casing, can be made by a nut threaded on the shaft at the accessible top portion of the motor.
