How Can We Help?
What Is Generator Rewinding?
Generator rewinding is a cost-effective solution for restoring older generators and electric motors to peak performance. Over time, winding coils naturally deteriorate, reducing efficiency and increasing the risk of power loss. Our generator rewinding service replaces worn copper windings within both rotating and stationary components, returning your generator to optimal operating condition. Where required, supporting steel laminations are also renewed to enhance durability, reliability, and long-term performance – helping you avoid costly generator replacement and unplanned downtime.
How Can Generator A Rewind Help You?
If your generator is relied upon to supply power to critical areas of a building site or forms an essential part of your daily operations, maintaining its condition is vital – particularly where no alternative power source is available. Generator rewinding should be viewed as a natural extension of routine generator servicing, helping to restore efficiency, improve reliability, and extend equipment lifespan. By reducing the risk of failure and delaying the need for costly replacement, rewinding offers a practical, cost-effective solution for long-term power continuity.
How Do You Know You Need A Generator Rewind?
One of the clearest indicators that a generator rewinding service is required is deterioration or failure of the stator windings. The stator, a ring-shaped component wound with copper cables, plays a critical role in converting the generator’s rotating magnetic field into usable electrical current. When these windings begin to degrade, generator performance is significantly affected.
Depending on the extent of the damage, failing stator cables can prevent a generator from starting altogether. This often leads to the assumption that a full generator replacement is necessary, when in many cases, professional generator rewinding provides a far more cost-effective solution. Stator rewinding is a normal and recurring part of a generator’s lifecycle.
Additional signs that generator rewinding may be required include poor winding resistance, reduced insulation resistance, overheating, and malfunctioning electrical components. Early detection and timely rewinding help restore performance, prevent unexpected downtime, and extend the operational life of your generator.

We offer a cost-effective generator servicing and maintenance services all across the UK.
For many businesses, the cost of going offline, even temporarily, can be detrimental. Emergency power supply is crucial.
Short-term or long-term – no matter what you need, our experienced team can handle the logistics.
The Common Causes Of Generator Rewinds
Our experts at Pleavin Power recommend monitoring three key indicators that may signal the need for a generator rewinding service. The first and most common is a drop in winding resistance, even if the change appears minor. Identifying this early helps determine whether shorted coils are the root cause of performance issues.
Optimum winding resistance values are typically engraved on the generator nameplate or outlined in the manufacturer’s documentation. If testing shows a consistent decline from these specified levels, a generator rewind is likely required to restore safe and efficient operation.
The second indicator is a reduction in insulation resistance, which is often the underlying cause of winding faults. Effective insulation is essential for controlling internal heat. When insulation resistance falls, the risk of overheating increases significantly, potentially leading to serious internal damage.
Finally, general deterioration of generator components is an unavoidable factor over time. Depending on usage and operating conditions, issues such as burn marks, corrosion, rust build-up, and mechanical failure can develop. For this reason, generator rewinding is considered a core element of generator servicing, helping to maintain reliability, extend lifespan, and prevent costly breakdowns.
How Can Pleavin Power Help You?
We carry out rigorous testing before any generator rewinding work begins. This includes comprehensive before-and-after burnout assessments. If test results show an increase of 20%+, this is flagged as a serious concern and addressed accordingly.
We perform detailed resistance measurements to identify changes in copper losses, alongside testing for rotor losses. If rotor damage is detected, it is prioritised immediately.
Whether you have already identified warning signs within your generator or it has been some time since its last condition assessment, the decision to rewind ultimately lies with you.
Why Choose Pleavin Power for Generator Rewinds?
Our generator rewinding service is just one of the many solutions we offer to help protect and extend the life of your generator. By restoring your generator to optimal condition, rewinding provides a cost-effective alternative to replacement while improving reliability and long-term performance.
