Jershtech DC Motors
The Direct Source for Precision Motion Control: 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.
In the landscape of electromechanical engineering, the 27mm diameter DC motor (often referred to within the RC390/RC395 series framework) serves as a critical "sweet spot" between compact form factors and substantial torque output. As industries move toward miniaturization without sacrificing performance, understanding the nuances of 27mm motor technology is vital for procurement heads and R&D engineers alike.
The demand for 27mm DC motors is projected to grow by 6.4% CAGR through 2028. This is driven by the rise of "last-mile" delivery robots, portable medical diagnostic tools, and high-precision automotive actuators. We are seeing a significant shift from traditional brushed commutation to coreless and brushless (BLDC) designs in the 27mm frame size to achieve higher power density and thermal efficiency.
Global enterprises are moving away from "lowest-cost-only" sourcing toward "resilient supply chains." For a 27mm motor, reliability (MTBF) and EMI suppression are now the primary KPIs. Buyers in the EU and North America increasingly require ISO 9001:2015 certification and RoHS compliance, making the choice of a verified Chinese exporter like Jershtech a strategic necessity rather than just a cost-saving measure.
At Jershtech, we have transitioned into the Industry 4.0 era. Our production lines integrate fully automatic winding machines and real-time QC monitoring. This reduces human error in delicate tasks like commutator soldering and hobbing, ensuring that every 27mm motor—whether it's for a car central lock or a robotic arm—meets the exact same performance curve.
We operate with a simple philosophy: Engineered to last, built to fit. 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.
Our lab is equipped with the Coordinate Measuring Machine (CMM) and Salt Spray Test Chambers to simulate harsh environmental conditions. Every 27mm motor design undergoes life aging tests in our soundproof rooms to guarantee decibel levels stay within your specific application requirements.



Utilizing our FC280 motors, global car manufacturers implement reliable central locking systems and mirror adjustments. These 27mm-width motors provide the high stall torque needed for safety-critical components while maintaining a low weight profile.
From automatic window blinds to smart door locks (N20 series), our motors integrate seamlessly with wireless controllers. The low-noise battery-powered permanent magnet construction ensures longevity in consumer electronics.
Precision is non-negotiable in medical pumps and diagnostic tools. Our 24mm to 28mm brushless solutions offer the sterilized, quiet, and maintenance-free operation required for clinical environments.
