Jershtech DC Motors
Shenzhen Jershtech Technology Co., Ltd. stands at the forefront of the precision micro-motion industry. As a leading China DC motor factory, we integrate over a decade of mechanical engineering experience with the agility of "Industry 4.0" manufacturing. The 12mm DC motor—often referred to in the industry by its N20 form factor—has become the gold standard for applications requiring high torque density in a compact footprint.
The global demand for micro motors is pivoting toward "high-efficiency, low-noise" profiles. As IoT devices and wearable tech evolve, the 12mm DC motor is being redesigned with NdFeB (Neodymium) magnets to provide up to 30% more torque without increasing physical dimensions. We are seeing a 15% YoY growth in medical surgical robotics and smart lock sectors specifically for 12mm geared solutions.
Modern B2B buyers no longer look just at the "unit price." The focus has shifted to TCO (Total Cost of Ownership) and ESG (Environmental, Social, and Governance) compliance. Our factory addresses this by providing full material traceability and energy-efficient motor designs that exceed EU RoHS and CE standards, ensuring seamless integration into global supply chains.
In a volatile global economy, Jershtech offers "Supply Chain Resilience." Located in Shenzhen, the heart of the world’s electronics ecosystem, we leverage a localized supply of raw materials—from high-purity copper wiring to precision-cut gears—reducing lead times by 25% compared to regional competitors.
Our philosophy is simple: Engineered to last, built to fit. Every 12mm DC motor that leaves our Shenzhen facility undergoes a battery of tests using advanced instrumentation, ensuring that the performance you see on the datasheet is exactly what you get in the field. From automatic winding machines to coordinate measuring machines (CMM), our equipment represents the latest in precision manufacturing tech.
In North American and European medical markets, 12mm DC motors power insulin pumps and portable diagnostic tools. The low EMI (Electromagnetic Interference) signature of our micro motors ensures they do not interfere with sensitive laboratory sensors.
In the burgeoning Asian and Middle Eastern smart city projects, our motors are used in facial-recognition smart locks. High torque at low RPM (revolutions per minute) is critical for moving heavy deadbolts reliably over thousands of cycles.
Weight is the enemy of flight. Our 12mm N20 series provides the necessary actuation for gimbal stabilizers in micro-drones. The balance between weight (approx. 10g) and output force makes them indispensable for lightweight robotics.
The lifespan depends heavily on the load and duty cycle. Typically, a high-quality brushed 12mm motor with carbon brushes can achieve 500-1,000 hours of continuous operation. For applications requiring 5,000+ hours, we recommend moving to our 12mm brushless (BLDC) variants.
Yes. As a direct factory, we offer customized gear ratios ranging from 1:10 up to 1:1000. Our engineering team can adjust the material of the gears (brass, steel, or plastic) to balance cost and durability based on your torque needs.
Consistency is managed through our automated production lines. By using automated winding and soldering machines, we minimize human error. Furthermore, each batch undergoes a 100% comprehensive electrical parameter test before shipping.
For stock items, we ship within 3-5 days. For custom OEM orders, the typical production lead time is 15-25 days. We offer air, sea, and express (DHL/FedEx) shipping options to meet global procurement schedules.
