    Motor Overhauls & Reconditions

    Whether your motor needs some minor reconditioning, or a complete restack and rewind, TAW Service Centers have no equal. Our technicians are fully equipped to tackle the most complex motor issues and get your equipment running better than new.

    TAW’s technicians first test your motor, then share their diagnostic findings and proposal of work to you before any work occurs. We use the highest rated materials and equipment to provide outstanding overhauls and other modifications like voltage upgrades, insulation reinforcement, and rewinding for horsepower upgrades. We can also make complex mechanical changes such as shaft straightening or replacement, rotor restacking, stator lamination repair, frame modifications, and cooling enhancements.

    If your motor doesn’t need a total overhaul, but still requires some TLC, TAW also offers reconditioning services:

    • Disassembly
    • Cleaning
    • Reinsulating and undercutting
    • Balancing and reassembly
    • Bearing replacement
    • Commutator turns

    Motor Retrofits & Redesign Services

    Whether you need a lighter, faster, more efficient, or just more powerful piece of equipment, we can redesign it to be safe and reliable while meeting your specifications and US safety standards. Our design team is capable of frequency conversions, speed change rewinding, conversion to inverter duty, horsepower improvement, voltage changes, reconnections, and more.
