Vacuum Cleaner Motor Copper Commutator Spare Part

High-Performance Vacuum Cleaner Motor Copper Commutator Spare Part – Precision-Engineered Home Appliance Spare Part for Reliable Motor Operation

Jiangsu Angu Electric Appliances Co., Ltd specializes in manufacturing the Vacuum Cleaner Motor Copper Commutator Spare Part Model J-86, a segment-type commutator crafted from premium silver copper alloy (0.03% or 0.08% Ag content) combined with high-temperature phenolic resin. The precision element is made of 22 pieces with precise outside diameter of 23.4mm, inner diameter of 9.6mm and height of 19mm to fulfil the tough demands of high-speed motor applications. Angu is ISO 9000 and IATF 16949 certified to manufacture 50,000 pieces in 30 days with over 20 years experience in manufacturing and a comprehensive range of OEM/ODM assistance and SGS certification.

Superior Material Composition for Enhanced Durability

It is manufactured from a silver-bearing copper alloy, which has a much higher recrystallization temperature than the normal electrolytic copper. This material selection eliminates segment deformation under intense temperature conditions created by motors running at speeds above 30,000 RPM.

The silver concentration (0.03% to 0.08%) improves electrical conductivity and maintains structural integrity during high heat brazing operations. The advanced phenolic resin insulation combined with this arrangement provides dielectric strength above 2500V/50Hz/1s . It is a great performance for the tough environment in household appliance.

Our production method is hardened to 80-120 HRB for maximum balance between wear resistance and electrical contact stability. The regulated surface roughness of 0.4-0.8µm enables optimum patina coating growth and reduces carbon brush wear.

Technical Specifications of Vacuum Cleaner Motor Copper Commutator Spare Part

Precision Engineering for Zero-Defect Performance

Every commutator undergoes rigorous quality control protocols aligned with international motor industry standards. Our Total Indicator Runout (TIR) tolerance remains below 0.005mm, ensuring perfectly cylindrical contact surfaces that eliminate brush bounce and electrical arcing.

The reinforced hook structure design withstands centrifugal forces at extreme rotational speeds. Spin testing at 1.2 to 1.5 times rated RPM confirms zero segment displacement under operational stress conditions.

Bar-to-bar resistance testing verifies electrical uniformity across all 22 segments, preventing unbalanced current flow that causes motor vibration and premature failure. Precise mica undercutting depth maintains proper carbon brush seating while preventing insulation protrusion that triggers sparking issues.

Versatile Applications Across Home Appliance Motors

This Vacuum Cleaner Motor Copper Commutator Spare Part serves as a critical replacement component for various home appliance motor systems. Its design accommodates universal and DC motor configurations commonly found in vacuum cleaners, power tools, and floor care equipment.

The moisture-resistant phenolic resin insulation adds functionality for humid conditions and is ideal for wet-dry vacuum applications. The anti-corrosive copper alloy provides long-term durability under various working situations.

This item may be integrated into maintenance services, aftermarket spare part distribution or original equipment manufacture programmes. Standard sizes provide easy interchangeability and the variety of possibilities for the customisation for specific motor designs.

Flexible Customization and Scalable Production

Angu offers complete OEM/ODM capabilities with adjustable minimum order quantities. MOQ The standard MOQ for this model size is 10,000 pcs. Custom mould creation is available for unique applications.

Our mould fee refund policy allows purchases to accumulate over three years, reaching 500,000 pieces, making investment in bespoke tooling financially feasible for long-term collaborations. Engineering teams work on dimensional changes, number of segments, material grades.

Production scheduling is done for normal replenishment orders and also for urgent replacement requests. We provide maritime freight, air cargo and express courier services (DHL/FedEx/UPS) to deliver your orders on time anywhere in the world in well-protected packaging.

Quality Assurance and Technical Support

Each manufacturing batch undergoes dielectric/hi-pot testing to confirm the insulation integrity between segments and the shaft assembly. Laser micrometres are used to test the surface finish to verify dimensional correctness before shipping.

We provide 1 year guarantee on material and manufacturing faults, and you may return, exchange or replace it if there are quality concerns. Technical support may help you with installation problems, troubleshooting, and optimising motor performance via precise component matching.

Factory audit services (virtual & on-site) gives you insight into production operations. Documentation comprises test reports, material certificates and traceability records to meet your quality assurance needs.

FAQ

Q：What is your pricing structure?

A：Pricing fluctuates with SMM/LME metal market rates and varies based on material grade, dimensional specifications, and order volume. Contact our sales team for current quotations specific to your requirements.

Q：What is your minimum order quantity?

A：Standard MOQ is 10,000 pieces for smaller commutator models and 5,000 pieces for larger configurations. Custom orders have flexible MOQ depending on tooling and production complexity.

Q：Do you support custom mold development and what are the costs?

A：We fully support new mold creation for specialized designs. Mold fees are refundable when your cumulative purchases reach 500,000 pieces within a three-year period.

Q：Can you accommodate factory audits?

A：Both online virtual audits and on-site physical inspections are available to verify manufacturing capabilities, quality systems, and compliance certifications.

Q：How does the commutator prevent excessive sparking during operation?

A：Sparking typically results from high TIR runout, improper mica undercutting, or incorrect carbon brush grades. Our precision machining maintains TIR below 0.005mm, while controlled mica depth ensures proper brush contact, eliminating common sparking causes.

Q：Why choose silver-bearing copper over standard copper?

A：Silver additions significantly raise the softening temperature, preventing segment deformation during high-heat manufacturing processes and sustained high-speed operation. This extends commutator lifespan and maintains dimensional stability.

Q：What causes bar lifting failures in high-speed applications?

A：Bar lifting occurs when reinforcement structures cannot withstand centrifugal forces at extreme RPMs. Our hook-reinforced design and high-temperature resin compound pass rigorous over-speed testing to prevent this failure mode.
