Deploying state-of-the-art permanent magnet technology, precision gear assemblies, and strict thermal validation for critical vehicle applications.
At TTM Motor and Shunli, 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.
The automotive sector is undergoing its most radical transformation since the introduction of the assembly line. Driven by electrification, autonomous driving systems (ADAS), and a surge in luxury cabin automation, the modern passenger vehicle requires an unprecedented array of electric motors. While traction motors drive the wheels, a typical high-spec EV utilizes up to 100 micro-drive systems to operate sub-assemblies ranging from automated charging doors and flush handle actuators to thermal valves, LiDAR optical drives, and electronic parking brakes.
Currently, the automotive electric motor supplier landscape is segmented into Tier-1 mega-manufacturers (such as Nidec, Bosch, Mitsuba, and Denso) focusing on high-volume standardized powertrain motors, and specialty suppliers like TTM Motor and Shunli, which focus on highly customized, high-reliability micro-drives. These micro-drives require specific structural geometries, complex planetary and worm gear arrangements, and compliance with strict automotive environmental metrics.
Maximizing electromagnetic flux paths within ultra-compact spatial limits. Essential for power locks and compact actuators.
Advanced shielding designs integrated directly onto the motor PCB to ensure zero interference with automotive CAN bus lines.
Engineered to operate reliably in wide temperature profiles ranging from -40°C to +125°C, matching global automotive norms.
From initial design optimization to rigorous raw material sourcing, automated assembly lines, and severe stress-testing regimes, every phase of production is subject to total traceability control.
To achieve the tight mechanical tolerances required for low-backlash automotive planetary gearboxes and low-noise worm actuators, we invest in the world's most advanced tool manufacturing systems.
To achieve IATF 16949 compliance, every production batch is subjected to comprehensive testing in our dedicated verification laboratory, simulating up to 10 years of harsh vehicle operation.
Our quality control inspectors utilize precision digital micrometers to conduct double-pass inspections on custom gearmotor shafts before main housing assembly.

Micro-drives must operate under varying dynamic loads while complying with international automotive standards. To meet these demands, we offer specialized micro-drive solution architectures:
1. Smart Cabin Comfort & Automation: Utilizing low-noise brush and brushless DC gearmotors for power seats, steering wheel columns, and electronic air conditioning vents. Our JGY-370 and JGY-385 series offer low-noise, high-torque reduction profiles suited for interior cabin integrations.
2. Automated ADAS & Exterior Actuation: Incorporating high-efficiency planetary gearboxes (such as our customizable 22mm and 36mm series) for active aerodynamics (grille shutters, retractable spoilers) and sensor cleaning systems. These require robust seals to protect against dust and water ingress.
3. Secure Entry & Locking Assemblies: Engineering high-efficiency, sub-compact worm-gear and screw-drive configurations for automated door locks, sliding trunk lids, and electronic fuel-filler or charging-port latch mechanisms.

The micro-motor industry is shifting from traditional brushed topologies to brushless designs (BLDC) and integrated smart electronics. Our engineering roadmap focuses on three main developments:
Transition to High-Density Brushless Drives: By eliminating physical brushes, BLDC architectures extend operational life, minimize acoustic noise, and eliminate electromagnetic arcs. This is essential for clean-room medical components and high-integrity automotive actuators.
Integration of Embedded Sensors: Incorporating high-resolution magnetic Hall-effect encoders directly into planetary gearheads to provide precise closed-loop feedback, allowing control systems to monitor angular speed and shaft positioning within fractions of a degree.
Advanced Metallurgy & Material Selection: Utilizing premium sintered NdFeB magnets and plastic-metal hybrid planetary gear carriers. This reduces total assembly mass, improves thermal dissipation, and helps prevent gear teeth failure during mechanical block conditions.
