Engineered specifically for extreme performance, high voltage stability, and long functional lifespans under continuous load conditions.
Hungary has transitioned into a major hub for European manufacturing, particularly in the automotive, smart household appliance, and industrial electronics sectors. Under the "Eastern Opening" policy and direct European integration, the country attracts substantial FDI. Regions like Central Hungary, Western Transdanubia, and the industrial centers of Debrecen, Győr, Miskolc, and Kecskemét are home to advanced processing factories, OEM parts suppliers, and high-tech electronic sub-assembly operations.
As global demands tilt toward resource efficiency, electrical safety, and precise actuation, manufacturing units across Hungary require micro-drive components that bridge cost-efficiency with uncompromising operational reliability. High-voltage (HV) brushed DC motors—typically operating in ranges such as 100V, 120V, and 240V—remain crucial. They power central vacuum systems, HVAC fans, medical treatment chairs, automated fluid pumps, and linear actuating systems.
For Hungarian design engineers and procurement officers, sourcing reliable high-volt brushed DC components means navigating critical trade-offs between electromagnetic compatibility (EMC), thermal limits under heavy cyclical load, and delivery lead times. Working with an ISO9001-certified exporter with established R&D pipelines ensures high yield rates, standardized safety certifications (CE, RoHS, REACH), and continuous engineering support.
All motor configurations are calibrated to meet CE EN 55014 and RoHS/REACH regulatory limits, ensuring smooth integration into European consumer products.
Efficient logistics directly to main logistical depots in Budapest, Győr, and Debrecen with flexible trade terms (FOB, CIF, DDP).
Shaft extensions, armature windings, brush configurations, and bracket mounts are customized to match exact mechanical envelopes.
High-voltage brushed DC (HVBDC) motors serve a unique niche where low-voltage solutions cannot deliver sufficient power density without drawing excessive current, and brushless (BLDC) motors present unacceptable cost, controller complexity, or electromagnetic interference (EMI) profiles.
Operating at voltages around 120V to 240V requires careful engineering of the mechanical commutation assembly. Commutator bars are made of high-conductivity oxygen-free copper, and segments are insulated using precision-cut mica sheets. Custom-formulated carbon-graphite brushes provide the optimal balance of electrical conductivity and friction properties. This extends brush life, reduces electrical arcing, and mitigates electromagnetic emissions.
High-voltage stresses demand advanced insulation. Our motors use Class F (155°C) and Class H (180°C) enameled copper wire. armatures are reinforced through a drip-impregnation system using high-temperature polymer resins. This ensures they resist centrifugal stress, withstand high thermal loads, and maintain insulation integrity to prevent turn-to-turn shorts during rapid acceleration.
A key challenge in brushed motors is suppressing high-frequency noise generated by commutation arcing. Our designs incorporate varistors directly on the commutator, along with inline inductance and capacitance filtering options. These measures absorb voltage spikes, keep conducted emissions within acceptable EN limits, and protect nearby microcontroller circuitry in smart systems.

At TQC Micromotor, we believe that global innovation shouldn't be limited by size. For two decades, we have dedicated ourselves to a single, relentless pursuit: designing, engineering, and manufacturing high-performance micro-drive solutions that keep modern industries moving forward. Based in China, we operate a state-of-the-art, ISO9001-certified production facility specializing in Micro DC Motors, DC Gear Motors, and Brushless DC Motors (BLDC).
The name TQC represents our foundational pillars: Top Quality & Customization. We understand that applications like smart home automation, medical devices, automotive electronics, and precision robotics demand uncompromised reliability. That is why every TQC micro motor is built with an exceptional power-to-size ratio, ultra-low noise acoustics, and an extended operational lifespan, backed by strict 100% in-house quality control and international certifications (CE, RoHS, REACH).
We don’t just supply standard hardware; we act as a strategic R&D partner. With a robust engineering team holding multiple industry patents, TQC thrives on solving complex mechanical challenges through flexible OEM/ODM custom solutions. From custom shaft configurations and custom voltage tuning to specialized bespoke gearheads, we turn your technical blueprints into high-volume, cost-effective reality.
The stability of a high-voltage brushed motor depends on the precision of its assembly line. At TQC, every stage—from lamination assembly to dynamic rotor balancing—is completed on automated and semi-automated machinery to eliminate manual variability. Check out our physical processes below:
In the modern B2B manufacturing landscape, product quality is only one part of the equation; supply chain security is equally critical. For industrial buyers in Hungary, sourcing components directly from our specialized factory in China provides a competitive balance of cost efficiency and manufacturing scale.
Our raw material supply chain—spanning high-coercivity permanent magnets, heat-resistant copper wires, and durable carbon brushes—is secured via long-term partnerships in China's industrial clusters. This structural depth buffers our clients from sudden price spikes and guarantees production continuity. Additionally, we work with direct rail shipping options via the New Silk Road (Chengdu-Budapest link), which delivers sea-freight economy at air-freight speeds. This allows Hungarian factories to optimize inventory turns and reduce safety-stock requirements.
Our comprehensive series features robust frame designs (36mm and 42mm) tailored for diverse installation configurations and power profiles.
Different operating environments require specialized micro-drive designs. Our engineering team designs motor configurations optimized for the operating profiles, ambient conditions, and mechanical setups of European systems.
Used in smart vacuum cleaners, coffee grinders, and motorized ventilation units. For these applications, we focus on acoustic optimization (reducing high-frequency brush whine to below 50dB) and custom brackets to simplify automated factory assembly.
Our 36mm (RS5512, RS5612) and 42mm (RS7712, RS7812) series supply high starting torque. This is critical for driving gear assemblies in heavy dampers, rolling shutters, and medical beds, ensuring reliable startup under mechanical loads.
Continuous duty in marine and industrial equipment requires reliable thermal management. Our motors utilize internal cooling fans and optional ventilation slots in the steel housing. This improves heat dissipation and prevents thermal runaway during continuous operation.
In the automotive sector, we optimize our motors for vibration resistance. Custom winding anchors, spot-welded commutator tabs, and dynamic balancing prevent mechanical fatigue under vehicle vibration profiles.
