Motors are prone to damages and failure. As your motor ages, it may start showing some signs of degradation. When this happens, you may need to consider generator rewinding servicing.
Generator rewinding, more commonly termed as “alternator rewinding,” is the process of rewinding the stator of a generator. Its main purpose is to get the generator back to its best condition and prevent further disruption of its processes.
Alternator rewinding needs to be done from time to time as part of your generator’s regular maintenance. This is mainly because your generator’s stator requires rewinding throughout the lifespan of your alternator.
However, there are certain factors that you first need to consider and question that you first need to ask before you have your alternator rewound. To know what these questions are, read on.
Does your alternator show physical signs of deterioration?
Before bringing your generator to the attention of an engineer, it is important to determine first whether or not your alternator really needs some rewinding. The best way to do this is to look for physical signs of deterioration.
Check your alternator for any broken parts, depleted metals, or any other indication of corrosion. Seeing some oil, water, rust, or grease on it is an obvious sign that your alternator is corroded. When it refuses to rotate, it may also indicate that your alternator is up for some rewinding.
On the other hand, if physical inspection doesn’t suffice and inform you of your equipment’s exact condition – you should consider generator overhauling for a clear overview of its state of health. An experienced engineer will thoroughly examine the equipment internally for any issues and suggest or offer solutions to resolving the problem.
Does your alternator have low insulation resistance?
If your alternator is not showing some apparent and physical signs of deterioration, but you are quite sure that it needs some rewinding, the next question that you can ask is whether or not your alternator is having low insulation resistance.
As its name suggests, insulation resistance is the ability of the insulation material to resist the flow of current. As the material ages, the performance of the insulation deteriorates.
To know if your alternator needs to be rewound, measure its overall winding resistance. Doing so will give you an idea whether or not there are any short circuit coils around your alternator.
You can also compare your alternator’s current resistance to the regular resistance specified by its manufacturer. If your measurement reveals inconsistent results, then your alternator may require rewinding.
Where should you have your alternator rewound?
After you have fully determined that your alternator indeed needs some rewinding, the next question that you should be asking is where you should have your alternator rewound.
Alternator rewinding is quite a technical process that needs some professional hands. To ensure that your alternator goes back to its premium condition, you need to have it rewound only by engineers who are knowledgeable and skilled on the process.
After asking and addressing the right questions to determining if rewinding is needed for your alternator – all that’s left is for you to engage a suitable professional who’s able to deliver.
