Questions

Frequently Asked Questions

What makes a motor 'farm duty'?
Sealed or protected enclosures against dust and moisture, overload protection, and bearings rated for long continuous run times. A standard open motor in a grain environment fails early. Farm duty units are built for exactly that abuse.
Do your farm motors meet efficiency standards?
Yes. All of our energy-saving motors meet NEMA and EPAct efficiency standards, which matters on motors that run all day.
How fast can you get a motor to my operation?
In-stock motors ordered by noon ship the same day, with overnight delivery available nationwide via FedEx and freight.
