Precision Commutator Solutions for OEM Motor Manufacturers
As an OEM, you need every commutator to install easily, run smoothly and pass your outgoing inspection without rework. XDC focuses on the details that matter inside your production line:
Tight mechanical tolerances
We control commutator runout to ≤ 0.002 inch, helping you achieve smooth rotation, low brush vibration and consistent torque. This stability supports long-term brush performance and reduces the risk of sparking.
Uniform commutator bar geometry
Each commutator bar and commutator segment is machined using CNC equipment and verified for width, height and angle, ensuring even current distribution across the armature.
Optimized mica insulation and slot design
We precisely undercut and deburr mica insulation and commutator slots, then thoroughly clean the assembly to remove all burrs and dust. This stable geometry supports quiet operation.
Controlled surface finish
The final surface finish is designed to quickly form a thin, uniform copper-oxide film during motor run-in. A stable film improves brush contact, reduces localized heating and keeps the surface easy to restore if your customer ever needs cleaning electric motor commutator surfaces in service.
Maintenance-centric design philosophy
We design from the viewpoint of your service team. Smooth surfaces, clean slots, and stable geometry mean less time with garnet paper and commutator stones, and more time with your DC motors in operation.


Consistent quality across batches
Our quality system is built so that the commutator you receive next year matches the performance of the one you install today. This consistency is essential for fleet maintenance, where cleaning procedures must behave the same way on every unit.
Broad application coverage
XDC produces commutators for:
- Industrial DC motors and generators
- Universal motors for power tools and appliances
- Traction and heavy-duty electric machinery
In each segment, we align our design with relevant IEC / NEMA-style requirements and leading OEM practices.


Engineering support from China’s premier commutator manufacturer
Our engineers can advise on:
- Matching commutator specifications to your carbon brush grade
- Optimizing geometry for your cooling and dust-collection environment
- Setting inspection points that keep cleaning and visual checks straightforward
Complete In-Factory Testing
Every production batch is checked using a combination of mechanical and electrical tests:
- Runout measurement – confirming the ≤ 0.002 inch limit on finished commutators.
- Bar-to-bar testing – verifying that each commutator segment carries current consistently.
- Insulation resistance – confirming robust isolation between copper bars and the core.
By the time an XDC commutator reaches your assembly line, it has already passed the key checks that support stable motor performance and straightforward commutator cleaning procedures if required in the field.

XDC Precision Customer Feedback
What we appreciate most about XDC is how fast they reply. If there’s ever a delay or any issue, they tell us directly instead of hiding it. That makes planning on our side much easier. Their attitude is very straightforward and cooperative.

We tried a few suppliers before, but either the price was too high or the quality was unstable. XDC gave us a very reasonable price, and the commutators are performing well in our tools. Our failure rate in testing has clearly gone down since we switched to them.

During a new motor project, XDC helped us adjust the design of the commutator several times. They gave practical suggestions instead of just doing exactly what we asked. That saved us time and a lot of trial and error. We’re very satisfied with the technical support from their team.

We’ve placed some urgent orders with XDC, especially before peak season. They managed to deliver on time and kept us updated on the production schedule. This helped us avoid shortages and kept our production line running smoothly.

We’re based in Europe and were a bit worried about the time difference at first. But the XDC sales team arranges calls at times that work for us, and emails are answered quickly. The communication has been very smooth, so the distance hasn’t been a problem.

FAQ – XDC Commutators & Maintenance
Here you will find answers to the most common questions regarding our manufacturing processes, ordering details, and quality standards. If you have a question that isn’t listed here, please contact our sales team directly.
XDC commutators are manufactured with tight runout tolerances, carefully undercut mica and smooth bar edges. This makes it easier for your team to wipe the surface clean, use light non-conductive abrasives when needed, and re-establish a stable running film without deep rework.
Yes. As a dedicated commutator manufacturer, we can customize diameter, bar count, slot design, insulation system and mounting interfaces to match your motor design and your preferred commutator cleaning practices.
Our products are engineered for applications where dust, moisture or process contamination demand regular commutator maintenance. Robust bonding of commutator bars, controlled copper hardness and precise slot geometry help the surface withstand repeated cleaning and inspection.
XDC builds its process around widely recognized DC motor repair and overhaul specifications for runout, mica undercutting, bar chamfering and electrical testing, while applying our own FMEA-based improvements to reduce high-risk failure modes such as grooving and copper drag.
We regularly collaborate with OEMs and repair centers worldwide. Our engineers can provide guidance on inspection intervals, suitable tools and recommended surface conditions that are compatible with XDC commutators, helping you formalize a clean, repeatable maintenance standard.
