Experts in rewinding industrial AC motors
AC motors work in tough conditions where heat, vibration, and electrical stress can cause the winding to fail or the insulation to break down. We use high-quality copper and insulation materials to completely replace damaged windings in our industrial AC motor rewind service. This brings the motor back to its original performance and efficiency. We fix and rewind:
We also offer related servo motor repair and DC motor repair services all in one place for applications that need precise control.
How We Fix and Rewind AC Motors
We use a controlled, quality-driven process for every AC motor rewind:
Initial inspection and diagnostics done in-house with our motor testing facilities
Remove and burn out bad windings
Core inspection and assessment to find hidden damage
Rewinding with OEM-grade copper for accuracy
Varnish impregnation for protection against heat and electricity
Replacing bearings and fixing up machinery
Last tests of the electrical and mechanical parts before they are sent back
We add condition monitoring services when needed to help stop future failures and support maintenance plans that are meant to keep things from breaking.
Common AC Motor Faults We Repair
Our engineers regularly resolve issues such as:
Burnt or shorted windings
Insulation breakdown and overheating
Bearing failure and shaft wear

Frequently Asked Questions
Below are answers to some of the most common questions we receive about AC motor repairs and rewinds. If you need further information or urgent support, our engineering team is always happy to help.
What is an AC motor rewind?
An AC motor rewind consists of removing damaged windings and replacing them with new copper windings and insulation materials. By following this procedure, we can restore the motor’s electrical performance while also extending its service life. As a result, this comprehensive overhaul ensures that the motor will continue to operate at peak efficiency for many years.
When should an AC motor be rewound rather than replaced?
Rewinding is often the best option when the motor is large, specialised, or obsolete. AC motor rewinds are typically more cost-effective and faster than sourcing a replacement, especially in breakdown situations.
What types of AC motors do you repair and rewind?
We repair and rewind single-phase and three-phase AC motors, including low and high voltage units, across all major manufacturers and industrial applications.
Do you replace bearings during an AC motor repair?
Yes. As part of our comprehensive AC motor repair and rewinding process, we thoroughly inspect bearings and other worn mechanical components. As a result, we replace any faulty parts as needed to ensure optimal performance. Furthermore, by taking an integrated approach, we ensure that we not only repair the electrical windings but also address any underlying mechanical issues. As a result, your motor is returned to optimal electrical and mechanical condition.
How long does a typical repair take?
Repair time depends on the equipment type and extent of damage. Standard repairs are often completed within a 15 days, while emergency jobs can be turned around in hours.
Can you repair obsolete or unsupported AC motors?
Yes. We specialise in repairing and rewinding obsolete AC motors that the OEM no longer supports. By focusing on legacy systems, we can help customers avoid the high costs associated with complete machine replacements. Furthermore, because we can recreate windings for discontinued models, we ensure that your current machinery continues to function for years to come. As a result, you save time and money by extending the life of your proven assets.
Are AC motor rewinds covered by a warranty?
Yes. Our 12-month warranty covers all AC motor rewinds and repairs. By offering this comprehensive guarantee, we demonstrate our complete confidence in the quality and dependability of our work. As a result, you can return your equipment to service with complete confidence, knowing that we fully support every repair we perform.
Do you offer emergency AC motor repair services?
Yes. Neutronic provides a 24/7 emergency AC motor repair and rewind service, including nationwide collection and delivery.
How do you test AC motors after rewinding?
Before we return any equipment, each motor is thoroughly tested electrically and mechanically. This process includes critical checks like insulation resistance and winding assessments, as well as complete performance verification. Furthermore, by conducting these rigorous evaluations, we ensure that each unit meets our exacting quality standards. As a result, you will receive a motor that is guaranteed to operate reliably from the moment it is reinstalled.
