What Is Electric Monitor Rewinding?
What are electric motor rewinding services and why do you need them? Rewinding is the process that we sometimes use as a way to repair shorted, grounded or damaged motor coils. When we perform our DC motor rewinding service for your motor, we can then return the rewound coil and reinstall it with rebuilt armatures or other components as needed to get your motor functioning properly again.
Steps for Motor Rewinding
When we perform our motor rewinding services, there are several steps we go through:
Record Pertinent Data
We start by recording all the necessary data that is needed to rewind the motor, including the number of slots, number of coil turns, pitch and necessary wire size for making coils to rewind the motor.
Remove Faulty Windings
Once we record the necessary data and enter it into our database, it’s time to remove the faulty windings. Following removal of the faulty windings, we must remove any leftover varnish, insulation or contaminants before rewinding the motor.
Use the buttons at the top of this page to contact us or to get a free quote on our machining and rewinding services for electric motors. We have a piece of equipment called a media blaster that is effective at removing debris and particles without damaging the motor.
Steam Clean the Stator and Paint With Insulation Paint
After this, we steam clean the stator and all the other parts of the motor to make sure they are free of contaminants. Once it is all clean, we paint inside the stator with insulation paint. We then install liner insulation in the stator slots so that the coils do not make contact with the core.
Make New Coils and Add to Stator Slots
Now its time to make new coils. The type of winding head we will use to wind the motor will depend on what type of motor it is. The person doing the winding tests the wire for any defects while the winding process is taking place.
Once the coils have been created, it’s time to add them to the stator slots as appropriate. When the coils are in place, we add wedging to insulate and protect the coil.
The next step is to add lacing for additional stability. Finally, we connect new motor leads followed by a thorough quality test. A dielectric test confirms the integrity and quality of the windings. The last step is to heat the motor in an oven for dipping in varnish. The varnish bonds the windings together and prevents the coils from moving. It also is a way to protect the windings from contamination.
Cure the Motor and Test
The last step is curing the motor and then re-testing to make sure that the motor is working optimally and as intended.
While this seems like an intense and heavily involved process, it is practically automatic for our trained technicians at Global Electronic Services. Our technicians have wound countless motors and know the process by heart. You can be confident that when you contact Global Electronic Services for your motor rewinding repair services, you will find yourself with a quality motor that works virtually like new at the end of it.

Global Electronic Services has perfected the process to rewind AC & DC motors, assuring exceptional repair and rebuild.
A properly planned and executed motor rewind will cause no efficiency loss in electric motors, but you may see improvements in power density, reliability and overall efficiency thanks to leading equipment and practices that your GES certified technician will use.
Your rebuild and motor rewind may include some additional improvements you haven’t considered, such as upgrades to the latest resins and insulating tapes that can improve overall thermal dissipation, especially when working on older motors.
As a qualified service provider, we always ensure your rewound motor is brought back up to OEM standards and efficiency expectations. Giving you the best rewinding service for electric motors starts with a complete review to understand if there is any problem with your motor that you were unaware of during submission.
If we discover anything, we’ll contact you right away with an updated quote and information on our concern. You must give us approval before any work is performed, so we are both in agreement for the final cost.
GES technicians hate it when we take our car to the garage for one thing and end up getting a bill for 20 others. We promise never to do that to you, which is why we have a thorough quote and approval process.
Our rewinding services for motors follow a very strict process to maximize speed and efficiency while minimizing any risk to core integrity. Core elements of our process include:
Windings are stripped carefully while the strength and structure of the core are maintained
Coils are rewound by a computerized machine to maintain regularity and accuracy
Rewind materials include copper and insulation
Windings are then tested electronically
Stators and armatures are processed through varnish machines to finalize the rewind
