The Shop That Fixes What Others Won't Touch
Out of options on an unusual motor? Bring it to the counter. Three generations of repair knowledge plus a network of industry connections means we devise solutions, not apologies.
Repairs, Rewinds, and Motors Rearranged to Fit
If you have an unusual motor you can't find parts for, you haven't exhausted your options until you've been here. Our staff repairs, rebuilds, and modifies motors, from fractional horsepower units to large electric motor repair for industrial equipment. That includes physically rearranging components so a motor fits into a tight spot the original never had to.
Whatever the custom project, the combination matters: three generations of hands-on experience and supplier connections throughout the industry. Call (314) 531-1888 or contact us to start.
Eight Steps Between a Dead Motor and a Like-New One
A motor rebuild here isn't a cleaning and a prayer. Every repair follows the full protocol:
- Complete disassembly and chemical cleaning to remove carbon buildup and debris
- Detailed inspection of stator windings, rotors, and shafts for structural integrity
- Bearing replacement with sealed, high-temperature grades rated for continuous operation
- Precision motor rewinding using Class H or F insulation to withstand thermal stress
- Vacuum pressure impregnation (VPI) with epoxy varnish against moisture and contaminants
- Dynamic rotor balancing to eliminate vibration and ensure quiet performance
- Full load testing under simulated operating conditions to verify amperage draw and efficiency
- Final quality assurance check of alignment and mounting specs before delivery
This is why a rebuild from this shop offers longevity comparable to a new unit, and why HVAC techs across the region send us the motors they can't save.
