Explore our top-performing precision brushed and customized motors engineered for high torque, low noise, and reliability.
Despite the rapid rise of brushless motor (BLDC) solutions, compact brushed DC motors (PMDC) remain an irreplaceable pillar in global industrial and consumer applications. Valued for their exceptional torque-to-volume ratio, linear speed-torque control curves, and highly cost-effective drive electronics, brushed motors dominate sectors that require high start-up torque, absolute mechanical simplicity, and robust operation in extreme environments.
Modern industrial automation, medical peristaltic pumps, automotive actuators, and precision consumer robotics demand extreme miniaturization. When coupled with high-reduction planetary or worm gearboxes, compact brush motors deliver tremendous locking torque and ultra-smooth low-speed movement. This makes them the ideal mechanism for smart door locks, automated valving, and critical security camera pan-tilt systems.
The manufacturing efficiency of China's brush motor factories extends far beyond raw labor cost savings. It is built on a highly integrated industrial ecosystem.
Instantaneous sourcing of high-grade NdFeB magnets, copper wiring, precision brush commutation materials (noble metal or carbon), and micro-gear hobbing. This proximity minimizes raw material lead times to just a few days.
Integration of high-precision horizontal gear hobbing machinery (such as Ningjiang machines), slow-feeding NC wire-cut machines, and EDM tools ensures components operate within sub-micron tolerances for minimal mechanical noise.
Rapid prototyping is our signature. Whether designing customized shaft configurations, integrating optical/magnetic encoders, or adjusting winding resistances to achieve optimal speed-torque operating points.
At TTM Motor, we don’t just manufacture motors—we engineer motion. We understand that in the world of advanced robotics, medical equipment, and smart automation, a fraction of a millimeter or a micro-level torque variance can dictate the success of your entire project. That is why our Shanghai-based R&D facility is dedicated entirely to pushing the boundaries of micro-drive performance.
Every micro DC motor, planetary gearhead, and brushless drive (BLDC) we produce is a result of rigorous cross-disciplinary engineering. Armed with advanced CAD/CAM software, automated winding technologies, and precision dynamic balancing testing equipment, our in-house engineering team bridges the gap between your conceptual design and volume manufacturing.
True to our Top Quality & Customization ethos, we specialize in solving complex integration challenges. Whether your application requires an integrated encoder for precise feedback, a custom-molded lead screw shaft, or a high-vacuum-compatible enclosure, TTM Motor has the technical expertise to customize and deliver ready-to-install motion sub-assemblies that meet your exact specifications.
From raw material selection to automated assembly and testing, every motor undergoes a standardized and highly controlled workflow.

From smart homes to industrial fields, customized PMDC and BLDC motors drive modern automated mechanical solutions.
High-torque micro gearmotors (such as 12mm N20 planetary setups) are essential for smart door locks, security safes, and home automation systems. The integration of high-reduction plastic or metallic gearboxes ensures a large holding torque in a very compact footprint, preventing manual override.
Customized 37mm gearboxes matched with high-RPM DC motors are widely deployed in coffee brewers, vending machine dispensers, and commercial ice makers. These systems require consistent rotation, food-grade lubricants, and high starting torque to grind or dispense materials reliably.
Lawn mower actuators require robust protection from moisture, dirt, and mechanical impact. High-power PMDC motors with 100mm square gearboxes or brushless alternatives handle extreme radial load stresses, providing 100kg+ torque levels to adjust blade heights or drive the wheels.
Compact brushed motors with low electromagnetic interference (EMI) profiles are utilized in automated massage chairs, medical pumps, and diagnostic equipment. They provide silent, vibration-controlled operations that respect strict patient comfort regulations.
Answers to critical technical queries for global engineering and procurement professionals.
A: By mating high-RPM micro motors (like the N20 or 390 series) with multi-stage planetary gearboxes. Planetary configurations distribute torque loads across multiple planet gears, increasing torque capacity while keeping the diameter under 12mm-28mm.
A: Absolutely. Our Shanghai factory supports full customization of output shafts (D-cuts, cross-drilled, keyed, thread-milled, or custom lengths) and custom harness terminations (JST, Molex, or custom PCBs).
A: Brushed motors offer lower initial drive cost, simpler control requirements (requiring just two wires for voltage application), and linear torque-speed delivery. This makes them highly reliable for basic actuation tasks without complex encoder electronics.
A: We use specialized noise testing chambers to measure decibel levels at set distances. Life cycle testing is executed in our automated aging shelves and constant temperature-humidity chambers to replicate extreme environmental degradation.
A: We offer both options based on application requirements. Heavy-duty applications use precision sintered steel gears for maximum lifetime. Light-load applications (like smart toys) utilize injection-molded plastic gears to minimize cost and acoustic noise.
A: Standard modifications (shaft changes, wire harnesses) take about 2-3 weeks for samples and 4-5 weeks for mass production. Complete ground-up developments require 6-8 weeks for mold building and validation.
