Baldor’s Grain Dryer Motors Made Simple: What You Need to Know


Baldor has continually produced premium motors to ensure that industrial zones are as productive as possible. Since then, Baldor has developed a remarkable series of motors known as Grain Dryer Motors, which is a subcategory of Farm Duty Motors.

Baldor introduced the Farm Duty motors product line to increase productivity and strengthen safety in challenging agricultural conditions. Baldor’s Grain Dryer Motors offer the dependability required to maintain agricultural activities because they were built with features for harsh environments.

There are several variations of Baldor-Reliance Grain Dryer motors:

Grain dryer/centrifugal fans

These Grain Dryer Motors range in horsepower from 1 to 50, and their shafts are one inch longer than NEMA requirements. These motors have grease that is high-temperature and moisture-resistant. These Open Drip Proof (ODP) Motors include screens to stop trash and other debris from entering. These TEFC enclosure motors have sealed bearings that are permanently lubricated.

Grain dryer/vane axial fans

These motors can be found in OPAO (Open Air Over) or TEAO (Totally Enclosed Air Over) and range in power from 1 1/2 to 15 hp. These motors’ shafts are keyed, drilled, and tapped with an internal 1/4 – 20 tap that is 1″ deep. They are also 3/4″ longer than NEMA standards. For simple conduit connectivity, there is additionally a convenient lead location.

Universal Crop Dryer

These grain dryer motors are among the best available for the agricultural industries and have many benefits over other motors. The motors are specifically made to work with vane axial crop dryers. High full load efficiency, no mechanical switches to wear out and no noise or vibration from regeneration are all features of these motors, which help to lower running costs. 

The motors come in TEAO (Totally Enclosed Air Over) and OPAO (Open Air Over) configurations. This motor has a smooth start, Class F insulation, and is less susceptible to voltage changes. The motors’ shafts are 3/4″ longer than NEMA requirements. There is a single-phase permanent split capacitor (switchless) in addition to the normal thermostats in these motors. Power ranges for these motors are 5 to 15 horsepower. 

Features of Grain Dryer Motors

  • Two-part tan epoxy paint is available with P22 (Open) and IP54 (Enclosed) technology for harsh applications.
  • For better moisture resistance, these grain dryer motors have a V-Ring slinger and lip seal on the DE.
  • Double-sealed ball bearings are present that are lubricated for life increasing productivity and durability.

Common Applications of Grain Dryer Motors

  • Farm building fans
  • High-pressure grain drying
  • Vane axial fan crop dryers
  • Storage for commercial and farm applications

The agricultural sector is the main one where Grain Dryer Motors are widely used. There are several types of Grain Dryer Motors available, including:
