Explore our leading product range, engineered to meet strict tolerances and extreme torque requirements.
TQC Micromotor is a forward-thinking Chinese manufacturer redefining precision motion control in the micro-drive industry. We design and build high-efficiency micro DC and BLDC motors that power next-generation technologies worldwide.
Driven by our core philosophy—Top Quality & Customization—we combine advanced manufacturing tech with flexible engineering to provide global B2B clients with the transparency of a local partner and the cost benefits of a premier Chinese factory. Built to last. Engineered to fit.
Our micro precision gear solutions leverage advanced raw material technologies, such as carbon-fiber reinforced polyamides and high-performance polyetheretherketone (PEEK), to achieve superior wear resistance, excellent thermal stability, and low noise profiles. Through vertical integration, from tool design to high-volume injection molding, we ensure our global partners receive componentry that operates flawlessly in high-demand ecosystems.
Our end-to-end manufacturing capability spans from die parts processing and mold making to state-of-the-art metrology.
Driving the boundaries of micro motion transmission to achieve ultimate torque density and sub-minute rotational backlash.
The micro precision gear market is undergoing a transition from basic plastics to highly engineered polymers and metal injection-molded (MIM) alloys. TQC is pioneering the use of PEEK (Polyetheretherketone) combined with carbon fiber additives to design self-lubricating gearboxes operating from -40°C to +125°C. Key milestones on our technical roadmap include:
High-precision applications in surgical robotics and smart locking systems demand close-to-zero backlash to maintain positional accuracy. Through optimization of tooth profiles (specifically involute and cycloidal variants), our engineering team achieves:
Empowering multi-industry platforms with optimized torque transmission and custom mounting integration.
In medical infusion pumps and surgical tool attachments, failure is not an option. TQC manufactures 6mm and 12mm coreless DC gear motors featuring ultra-low vibration profiles. Our medical designs adhere to biological safety and fluid sealing protocols, preventing ingress of sanitary chemical washes.
Electronic locks, smart trash bins, and automated flip-lids require high start-stop holding torques within space-constrained housings. Our 10mm to 28mm plastic and metal hybrid planetary gearboxes offer the perfect balance between long-term cycling lifespan and competitive cost structures.
Unmanned aerial vehicles (UAVs) require high responsive frequency actuators for payload stabilization and gimbal control. Micro planetary gear motors from TQC optimize mechanical efficiency while reducing dead-weight, translating directly to extended battery life for field operations.
Combining the absolute velocity of local manufacturing ecosystems with digitalized smart factory controls.
Our facility integrates the complete downstream supply chain under a single operating standard. By housing CNC machining, EDM wire cutting, precision mold making, automated plastic injection, assembly, and coordinate-measuring inspection under one roof, we eliminate cross-company logistical delays and administrative friction. This creates a vertical production loop that directly increases speed-to-market.
China's mature supplier base in high-grade engineered plastics and specialized structural alloys allows us to source raw materials at highly competitive bulk rates without compromising performance benchmarks. Furthermore, our automated testing suites track production data in real-time, matching digital assembly files with individual batch profiles for comprehensive batch traceability.
In-house mold design and fabrication reduce lead time for prototype modifications from weeks to days.
Robotic pick-and-place systems assembly reduces human error while maximizing daily volumetric output.
Digital logging of all dimensional testing guarantees zero-defect shipments reach international distribution hubs.
Understanding and mitigating risks for procurement officers, sourcing managers, and system integrators.
Sourcing customized gear motors requires strict design coordination to prevent downtime. TQC aligns with international procurement teams by supporting every stage of the design-in process.
We analyze and optimize custom parts for injection molding or machining to reduce tooling costs and ensure high material yield rates.
Providing raw material test reports, dimensional inspection layouts, and prototype performance verification reports before mass production kickoff.
Standardizing guaranteed lead times, safety stocks for key materials, and dedicated account support for high-priority projects.
Supporting EXW, FOB, CIF, and DDP shipping configurations with robust shockproof, humidity-controlled outer packaging.
Ensuring absolute compliance with target market regulations to enable hassle-free customs clearance and end-product certifications.
To support global deployment, TQC ensures all plastic raw materials, metallic inserts, lubricants, and electronic connections are certified according to international standard frameworks:
We operate in compliance with ISO 9001:2015, with continuous updates targeting IATF 16949 pathways for automotive applications. Every batch of micro gearboxes receives:
Answers to critical engineering and supply-chain inquiries commonly asked by global procurement partners.
Plastic micro gears (such as POM, Nylon, or PEEK) offer excellent low-noise properties, self-lubricating characteristics, and are highly cost-effective for high-volume injection molding. They are ideal for applications like smart trash bins or medical infusion pumps. Metal micro gears (made from steel, brass, or via MIM process) are utilized when high torque output, wear resistance, and high shock-loading capabilities are required, albeit at a higher unit cost.
Yes. Customization is our core principle. We design custom planetary gear arrangements to meet specific output torque and speed requirements. Shaft geometry (D-cut, round, splined, threaded) and electrical leads/connectors are fully customized to match your existing housing design.
We use high-precision CNC hobbing machines and advanced slow wire EDM systems to fabricate injection molds with micron-level tolerances. Concurrently, our quality control lab uses Gear Meshing Instruments and Coordinate Measuring Machines (CMM) to test runouts and tooth profile errors on every production run, keeping rotational backlash below our clients' targeted specifications.
For standard modifications (shaft customizations or lead changes), prototypes can be delivered in 2 to 3 weeks. For complete custom gearbox developments requiring new injection molds or complex CNC tooling, development and sampling cycles usually take 4 to 6 weeks, which includes comprehensive quality evaluation and testing data.
Yes, all raw materials, plastics, lubricants, and metal components used in TQC Micromotor products comply with environmental regulations such as RoHS and REACH. Full compliance declaration documents and raw material test certificates are provided to our customers during the product evaluation process.
We work with global clients at all stages. We support small batches for prototype testing and early clinical/market verification, and we have the capacity to scale up to millions of units annually using our high-speed injection molding machines and automated assembly lines.
Complete product range supporting low-vibration, high-reduction ratio requirements for smart applications.
