Jershtech DC Motors
In the realm of electromechanical engineering, the 25mm DC gear motor stands as a benchmark for versatility. This specific diameter offers an optimal balance between torque density and space constraints, making it the "goldilocks" solution for designers of smart appliances, robotics, and automotive subsystems.
Shenzhen Jershtech Technology Co., Ltd. is a forward-thinking China DC motor factory bridging the gap between advanced manufacturing efficiency and global engineering standards. We design and build high-efficiency DC and BLDC motors that power modern robotics, automotive systems, medical devices, and smart automation worldwide.
Our 25mm series, often referred to as the GA25 or GM25-370, utilizes a spur or planetary gear train to reduce the high-speed output of a DC motor into usable, high-torque motion. By integrating cutting-edge manufacturing tech with reliable quality control, we provide global B2B clients with the transparency of a local partner and the cost advantages of a top-tier Chinese manufacturer.
Leveraging premium alloy gears and specialized lubrication, our 25mm motors achieve stall torques ranging from 1.5kg.cm to 10kg.cm, depending on the gear ratio (up to 1:500).
Engineered for 3V, 6V, 12V, and 24V DC systems, ensuring compatibility with mobile battery packs and industrial power rails alike.
For closed-loop control systems, our motors can be equipped with Hall-effect or optical encoders, providing real-time feedback for position and velocity.
Reliability in motion control isn't just about the design; it's about the process. Our facility is equipped with fully automatic motor production lines that minimize human error and ensure batch-to-batch consistency. "Engineered to last, built to fit" is our guiding philosophy.
Sourcing from Shenzhen Jershtech means tapping into the world's most concentrated ecosystem for motor components. From rare-earth magnets to precision gear hobbing, our proximity to upstream suppliers reduces lead times by 30% compared to international competitors. We offer Information Gain to our clients by providing detailed material data sheets (MDS) and manufacturing traceability that standard trading companies cannot provide.
UL-certified insulation and FCC-compliant EMI shielding for seamless entry into US and Canadian markets.
Fully REACH and RoHS compliant. CE marking available for all standard 25mm gear motor models.
On-the-ground engineering support and localized documentation for European and Southeast Asian distributors.






The 25mm gear motor market is shifting toward Miniaturization and IoT Integration. As devices become smarter, the demand for "silent" operation and "precise" feedback has skyrocketed.
