Engineered to meet tight tolerances, custom gear ratios, and dynamic load profiles.
At TTM Motor, we don’t just manufacture motors—we engineering 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.
How specialized Chinese manufacturing ecosystems drive global automation innovations.
China's Yangtze River Delta is home to the world's most concentrated micro-drive supply chain. At TTM Motor, we leverage localized access to high-grade NdFeB magnets, copper wires, and hardened steels, dramatically shortening lead times and reducing inbound material costs.
Unlike Western boutique workshops, China's high-tech facilities balance rapid prototyping with large-scale automated runs. Our production lines seamlessly shift from custom shaft modifications to high-volume output of thousands of units daily.
By automating labor-intensive processes like copper winding, dynamic balancing, and terminal soldering, we offer globally competitive unit costs without compromising on raw material quality or processing tolerances.

How TTM Motor DC brush and geared drives power next-generation automated systems.
Utilizing micro-cylindrical DC gear motors (such as the N20 series and 2215 steering gear), our solutions deliver high holding torque and low noise parameters, ensuring smooth actuation in domestic and industrial smart door locks.
Our micro permanent magnet DC motors are calibrated for linear speed-torque control. This response curve is vital for peristaltic dosing pumps, laboratory mixers, and surgical equipment requiring precise fluid management.
Combining heavy-duty planetary gearboxes (such as the 28mm and 36mm assemblies) with customizable magnetic/optical encoders enables seamless closed-loop control on Automated Guided Vehicles (AGVs).

|---|---|---|---|---|
| 8mm - 16mm | 1.5V - 12V | 50 RPM - 25,000 RPM | Up to 0.5 N.m | Smart Locks, Medical Devices, Micro Optics |
| 20mm - 28mm | 6V - 24V | 10 RPM - 15,000 RPM | 0.2 N.m - 3.0 N.m | Automotive Actuators, Dosing Pumps, Robotics |
| 32mm - 45mm | 12V - 48V | 5 RPM - 8,000 RPM | 1.0 N.m - 30.0 N.m | Rolling Doors, AGV Drive Wheels, Blenders |
How TTM Motor supports procurement teams with robust engineering documentation, compliance standards, and risk mitigation.
International procurement of electro-mechanical components demands more than competitive pricing. It requires strict adherence to international quality management guidelines and predictable logistical execution. TTM Motor matches these criteria, supplying complete PPAP (Production Part Approval Process) documentation, including FMEA (Failure Mode and Effects Analysis) and control plans, to our automotive and medical OEM partners.
Every micro motor manufactured at our facility complies with RoHS Directive 2011/65/EU and its amendment directives, along with the REACH regulation. We source raw materials from verified suppliers who provide material certificates for steel, copper wire, magnets, and synthetic lubricants. This protects our European and American customers from import compliance issues and liability risks.
To mitigate the risk of assembly-line stoppages, we offer flexible shipping agreements (FOB, CIF, DDP) and maintain safety stock options at our Shanghai warehouse. This guarantees that variations in shipping schedules do not disrupt your manufacturing operations.
Evaluating the future landscape of coreless, slotless, and specialized permanent magnet brushed drives.
High-end applications are increasingly moving toward coreless brushed DC motors. By removing the iron core from the rotor, inertia is reduced, permitting faster acceleration/deceleration cycles, while eliminating cogging torque for smooth rotation at low speeds.
Innovations in brush materials—such as carbon-gold alloy composites and advanced precious metal structures—are increasing the service life of traditional brushed DC motors up to 5,000 hours in demanding applications, bridging the gap with BLDC motors.
Modern micro drives require precise feedback. TTM Motor is leading the integration of high-resolution magnetic encoders (up to 1024 lines) directly onto the rear shaft extension of micro motors, enabling compact closed-loop servo control.
Addressing technical design, material specification, and compliance inquiries from procurement and design engineers.
The lifespan of a brushed DC motor is primarily limited by the wear of the carbon or precious metal brushes and commutators. Typically, precious metal brush systems operating under low-load conditions last between 1,000 and 3,000 hours, whereas heavy-duty carbon brushes operating at nominal loads average 2,000 to 5,000 hours. Proper bearing selection (ball bearings vs. sleeve bearings) and speed management also play key roles in lifespan optimization.
Planetary gearboxes (like our Planetary Geared series) offer high torque transmission efficiency (typically 70-90%) and a compact coaxial output, making them ideal for high-power-density applications. Worm gearboxes (such as the 12V Worm Gear series) provide lower efficiency (35-60%) but deliver right-angle output orientation and self-locking capabilities, which is advantageous for overhead doors and safety actuators.
Brush commutation inherently creates electrical arcing that generates high-frequency electromagnetic noise. We mitigate this by integrating varistors, ceramic capacitors, or transient voltage suppressor (TVS) diodes directly inside the motor housing. For applications with strict EMC requirements, we can supply specialized metal shielding sleeves and custom-designed LC filters on the external lead wires.
We offer extensive shaft customization options, including D-flats, keyways, external and internal threads, snap ring grooves, and cross-drilled pinholes. We also manufacture integrated worm or lead screws directly onto the motor shaft to reduce alignment errors and assembly costs for linear motion systems.
Our in-house metrology lab supports a complete suite of environmental validation tests, including salt spray testing (up to 96 hours for corrosion resistance), thermal shock cycling, ingress protection (IP54 to IP67 seals verification), humidity tests, and vibration/shock resistance profiles according to industrial standards.
