TQC Micromotor
Explore our flagship series of engineering-grade permanent magnet brushed motors. Engineered to supply extreme torque density, low acoustic signatures, and high RPM capabilities for automation 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.
Navigating the requirements of international commerce and precision engineering in smart technologies.
Modern applications require compact footprints that deliver high torque. Our motors (like the RS997 delivering up to 550W) utilize high-grade Neodymium and Ferrite magnetic compounds to maximize output without increasing frame size.
Continuous-duty applications in home appliances and marine pumps require low operating temperatures. The integration of silicon steel laminations and pure copper rotors minimizes core losses and thermal degradation.
Long brushes and carbon-copper commutators ensure consistent electric contact. Our specialized carbon brush composition reduces mechanical wear and electromagnetic interference (EMI) levels.
In high-speed operations exceeding 10,000 RPM (such as the RS7512 and RS7712 series), micro-vibrations can accelerate bearing wear and increase noise. TQC Micromotor integrates automated rotor balancing machinery to ensure residual unbalance is kept within precision thresholds, extending the service life of both carbon brushes and internal ball bearings.
