Industrial Commutator
An industrial commutator is the rotary electrical switch on a DC motor or DC generator that reverses current in the armature winding and allows smooth torque in one direction. In real plants, the industrial commutator is still the heart of countless brushed DC motors in heavy-duty applications where high starting torque, precise speed control and robustness are critical.
Wherever brushed DC motors deliver from 10 kW up to 5000 kW, XDC industrial commutators are engineered to provide stable commutation, low sparking and extended carbon brush life.

The high-density 57-bar configuration optimizes voltage distribution, significantly reducing the risk of flashover. Built with a robust 95.4mm OD, it delivers smooth power transmission for large DC motors.
17-Segment Commutator
Engineered with a prime 17-segment configuration, this unit effectively suppresses magnetic harmonics and cogging torque. It ensures smooth rotation and vibration-free performance for specialized industrial motor windings.
36-Segment Industrial Commutator
Featuring a high-density 36-bar design on a 36.5mm OD, this unit optimizes current distribution. It reduces localized heating at the brush interface, extending maintenance intervals for continuous-duty motors.
Testing and Quality Control from a Trusted Industrial Commutator Corp
As a dedicated industrial commutator corp, XDC invests heavily in testing and inspection to ensure each unit performs reliably from day one. Our quality system is based on ISO 9001 principles, and we support CE-compliant documentation where required.
Spin and Overspeed Tests
• Spin testing at elevated speed (often above rated rpm) and temperature to verify mechanical integrity
• Overspeed margins designed to meet or exceed OEM specifications, giving you wide safety margins in service
Electrical and Insulation Tests
• High-voltage dielectric testing between adjacent segments and between segments and ground
• Routine verification of creepage and clearance distances
• Resistance and continuity checks to confirm correct connections and uniform current distribution
Dimensional and Surface Checks
• Detailed dimensional checks for OD, ID, length and segment pitch
• Surface finish and runout inspections on the brush track
• Verification of the brush seating area to help achieve low-sparking operation from commissioning
Materials and Engineering
XDC engineers each industrial commutator from high-quality raw materials selected for mechanical strength, electrical performance and thermal stability.
Copper Segments and Insulation
- Electrolytic copper or silver-bearing copper segments for high conductivity and low losses
- Mica and resin-based insulation systems to withstand high voltages and limit partial discharges
- Heat-resistant insulation up to Class F or Class H depending on your specification
Mechanical Strength and Balancing
- Robust hubs in cast steel or SG iron for high mechanical strength
- Precision machining to ensure tight runout and concentricity tolerances
- Dynamic balancing of each commutator to reduce vibration and extend bearing life

- V-ring / shell-type commutators for large traction and mill motors
Why Choose XDC as Your Industrial Commutator Company?
Choosing the right industrial commutator company is about more than price. It is about reliability, technical support and long-term partnership.
Focused Expertise
XDC is not a general motor parts supplier. We are a commutator specialist. That focus means:
• Deep knowledge of DC motor and traction motor commutator design
• Practical experience with common failure modes such as bar lifting, sparking and uneven brush wear
• The ability to optimize segment geometry, materials and insulation to match your real operating conditions
Broad Capability
As a global-facing industrial commutator company, we support:
• Single emergency replacements and short runs for repair shops
• Medium batches for regional OEMs and system integrators
• Long-term series production with strict change-control for major motor manufacturers
Reliable Performance and Lifecycle Cost
Our goal is not just to sell a component. We help you reduce life-cycle cost by:
• Extending commutator and carbon brush life
• Minimizing unplanned outages
• Lowering maintenance effort through stable commutation and high build quality
Applications of XDC Industrial Commutators in Heavy Industry
Wherever you see a heavy-duty brushed DC motor, an XDC industrial commutator can be designed to fit.
Steel and rolling mills

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 – Industrial Commutator Selection and Use
A: Start from the motor nameplate and existing commutator. We need OD, ID, length, number of segments, operating voltage, speed and power. With this information and your application details, XDC can propose a matching or upgraded design.
A: Yes. Send us your drawing or a used commutator, along with photos and basic motor data. We reverse-engineer the design, define materials and tolerances, and supply a sample for validation before series production.
A: Our products operate in steel and rolling mills, cement and power plants, mines, paper and textile lines, marine applications, cranes and lifting systems, rail traction and many other heavy-duty environments.
A: Lifetime depends on load, speed, brush grade, maintenance and environment. With correct brush selection, proper seating, regular inspection and clean operating conditions, XDC commutators can run reliably for many years before resurfacing or replacement is required.
A: XDC focuses on commutators and related solutions for brushed DC motors and traction motors. If you also need industrial slip rings, our team can review your requirements and propose an appropriate solution or introduce trusted partners.
A: We provide installation guidelines covering shaft fits, keyways, tightening procedures, brush seating and recommended checks before start-up. For critical projects, remote support is available to help your team achieve low-sparking operation quickly.
