Factory Recertification Program

Factory Certified Refurbished & Renewed Electric Motors

High-reliability, cost-effective fit & function electric motor solutions up to 10,000 HP. ISO 9001:2015 remanufacturing backed by a 1-year factory warranty.

Cost-Effective Industrial Solutions

Refreshed & Remanufactured Specialty Motors for Global Procurement

The Louis Allis Factory Recertification Program provides international industrial buyers with a rapid, high-quality, and budget-friendly alternative to a brand-new custom motor build. When facing unexpected equipment failures or extended OEM lead times, factory recertified motors deliver immediate operational continuity while reducing capital expenditure by up to 50%.

Operated out of our ISO 9001:2015 certified manufacturing facility in Warrior, Alabama, our experienced engineering team custom-modifies surplus and legacy motor frames—both mechanically and electrically—to create an exact "fit and function" replacement tailored to your site's physical footprint, shaft dimensions, and electrical requirements.

Every recertified electric motor undergoes rigorous 100% load testing, VPI insulation treatment, and dynamic balancing. All units come backed by our comprehensive 1-Year Factory Warranty and full compliance with MIL-STD-2037 Navy Sealed System Winding specifications for harsh environments.

Field-Proven Results

Real-World Case Studies & Cost-Saving Benchmark

Discover how international industrial plants avoided costly shutdown downtime and achieved substantial capital savings through Louis Allis recertified motors.

24-Hour Emergency Dispatch

Concrete Plant: Rapid Emergency Replacement Avoids Line Shutdown

A major heavy-construction concrete manufacturing plant suffered a catastrophic motor failure on their main drive system, halting production. Lead time for a new replacement motor from original manufacturers exceeded several months.

Solution & Impact: Louis Allis pulled a surplus motor frame, modified the electrical characteristics and mounting footprint, performed full factory recertification, and dispatched the finished motor in under 24 hours—restoring production immediately and saving hundreds of thousands in potential downtime losses.

Paper Mill: 2,000 HP GE Synchronous Motor Modification

A pulp & paper facility running four 2,000 HP GE synchronous refiner motors discovered that their legacy back-up spare motor had dimensional differences preventing direct drop-in installation.

Solution & Impact: Rather than scrapping the spare or procuring an expensive new motor, Louis Allis re-machined the output shaft to match the exact GE dimensional drawing, re-positioned the base mounting feet, converted the frame from Open Drip to WPII with custom air filtration, and fully certified the unit—saving the customer $474,301.00.

Chemical Plant: 500 HP Ammonia Compressor Motor Replacement

A chemical processing plant required an immediate replacement for a critical 500 HP ammonia compressor motor failure during high-demand operation.

Solution & Impact: Louis Allis provided an in-stock factory recertified unit adapted specifically for hazardous chemical environment specs. Delivered on site in just 3 days for $32,639, saving the facility $27,792 compared to a new motor price tag while slashing weeks off delivery.

Quality Assurance

Our Rigorous 6-Step Motor Recertification Process

Every recertified motor undergoes comprehensive testing and restoration to meet or exceed original OEM specifications.

01

Disassembly & Inspection

Complete mechanical teardown, core inspection, ultrasonic cleaning, and 10-point precision electrical diagnostic evaluation.

02

Stator & Rotor Rewinding

Precision VPI (Vacuum Pressure Impregnation) insulation treatment using Class H/H+ materials and MIL-SPEC sealed winding systems.

03

Precision Machining

CNC shaft modification, sleeve installation, end-bell re-boring, and foot re-alignment to match customer drop-in specs.

04

Dynamic Balancing

Rotor dynamic balancing to ISO 1940 / NEMA MG-1 standards to ensure minimal vibration and maximum bearing life.

05

Full Load & Surge Testing

Comprehensive electrical testing under voltage load, surge testing, partial discharge testing, and thermal imaging verification.

06

Certification & Export Prep

Final epoxy coating application, 1-Year Warranty documentation, and heavy-duty heat-treated export wood crating.
