DC Motor Commutator for Handheld Power Tools

High-Performance DC Motor Commutator for Handheld Power Tools – Professional Grade Components from Angu Group

Angu Group manufactures precision-engineered DC Motor Commutator for Handheld Power Tools designed for professional-grade applications. Our model J-229 has 12 segments, 18.9mm outer diameter, 8mm inner diameter and 13.5mm height, quality silver copper and resin materials are used in the construction. We have more than 20 years of specialised manufacturing expertise and ISO 9001 and IATF 16949 certifications, and we produce commutators with Total Indicated Runout (TIR) of less than 0.005mm. Our plant can create 50,000 pieces within 30 days. It is a trusted supplier for power tool makers who need consistency and a longer motor life.

Why Choose Our Commutators for Power Tool Applications

Power tool manufacturers face constant challenges: motor burnout, inconsistent torque delivery, and premature component failure. Our products addresses these critical issues through precision engineering.

Each commutator undergoes strict quality control. We use silver-bearing copper that delivers electrical conductivity exceeding 95% IACS. This superior conductivity reduces heat buildup during continuous operation.

The 12-segment design ensures smooth current transfer. This configuration minimizes brush sparking and electromagnetic interference, extending both motor and tool life. Your customers get power tools that perform reliably, job after job.

Technical Specifications of DC Motor Commutator for Handheld Power Tools

Material Excellence That Delivers Results

Material selection determines commutator performance. We exclusively use Tuy Silver Copper grades 03 and 08 for segment construction.

Silver content increases the softening temperature of copper bars. This prevents deformation when your power tools operate under heavy loads. The material maintains structural integrity even when temperatures exceed 180°C during extended drilling or cutting operations.

Our phenolic resin insulation system provides dielectric strength up to 2000V AC. Bar-to-bar insulation resistance exceeds 100MΩ at 500V DC. This prevents electrical leakage and ensures safe operation for end users.

Surface finish stays below Ra 0.8µm. This smooth surface reduces friction between brushes and commutator, minimizing carbon dust accumulation that causes short circuits.

Precision Manufacturing Process

Twenty years of manufacturing expertise shows in every commutator we produce. Our production facility maintains strict dimensional tolerances critical for high-speed power tool motors.

We control segment height differences to within 0.005mm. This precision prevents brush bounce and arcing during rotation. Your motors run smoother with less vibration.

Mica undercut depth ranges between 0.4mm and 0.8mm. Proper undercutting prevents carbon dust buildup between segments. This extends maintenance intervals for your power tools.

Our assembly process ensures concentricity throughout the commutator body. Even at speeds exceeding 15,000 RPM, our components maintain balance and stability.

Customization Capabilities for Your Brand

Every power tool design has unique requirements. We support full OEM and ODM services to match your specifications.

Need different segment counts? Require modified dimensions? Our engineering team works with your designs. We hold 3 invention patents and 6 utility model patents, giving us the technical foundation to develop custom solutions.

Minimum order quantities start at 10,000 pieces for standard sizes like our J-229 model. Larger models require 5,000 pieces minimum. Custom orders have flexible MOQ based on your requirements.

We offer new mold development services. The mold fee becomes refundable when your total purchases reach 500,000 pieces within three years. This makes customization affordable for growing brands.

Quality Assurance You Can Trust

Our quality management system follows international standards. ISO 9001 certification ensures consistent manufacturing processes. IATF 16949 compliance brings automotive-grade quality control to power tool components.

Every production batch undergoes SGS certification testing. We verify electrical properties, mechanical strength, and dimensional accuracy before shipment.

Free samples are available for testing. You can evaluate our DC Motor Commutator for Handheld Power Tools in your actual power tool designs before placing volume orders.

We support both online and on-site factory audits. Visit our Xuzhou, Jiangsu facility to see our production capabilities firsthand.

Flexible Global Logistics

Getting components to your assembly line matters as much as quality. We offer multiple shipping options to meet your timeline and budget.

Sea freight works well for large volume orders. Air freight accelerates delivery for urgent requirements. Express services through DHL, FedEx, and UPS handle small shipments and samples quickly.

Standard lead time stays within 30 days for orders up to 50,000 pieces. Our stable production scheduling ensures you can plan inventory with confidence.

FAQ

Q：What is your price?

A：Price depends on SMM/LME metals, material, size and quantity. Contact us with your specifications for accurate quotation.

Q：What is your MOQ?

A：MOQ is 10,000 pcs for small sizes and 5,000 pcs for larger models; custom MOQ depends on requirements.

Q：Can you make new mold? Price?

A：We support new molds, and mold fee is refundable if total purchase reaches 500,000 pcs within 3 years.

Q：Do you support factory audit?
