In the rapidly evolving landscape of electromechanical engineering, the 28mm gear motor has emerged as the industry standard for high-density power delivery within constrained spatial envelopes. As a premier Custom OEM 28mm Gear Motor Factory, Shenzhen Jershtech Technology Co., Ltd. understands that motion control is no longer just about rotation—it's about the synergy of efficiency, noise reduction, and long-term reliability.
Modern applications in robotics, medical diagnostics, and automotive haptics demand motors that can provide high starting torque while maintaining a compact diameter. Our 28mm series, ranging from high-speed DC brushed variants to sophisticated BLDC (Brushless DC) models, serves as the heart of these complex systems. By integrating advanced planetary or worm gearboxes, we achieve reduction ratios that precisely match the target application's "Load-Speed" profile.
Information Gain: Unlike standard off-the-shelf motors, our OEM process involves magnetic circuit optimization. By adjusting the winding density and magnet grade (such as N42SH Neodymium), we can increase torque by up to 15% without increasing the motor's physical footprint.
The next generation of 28mm gear motors will feature integrated Hall-effect encoders and thermal sensors. This allows for real-time telemetry, enabling predictive maintenance and precise closed-loop control in robotic arms and surgical tools.
While brushed motors remain cost-effective for car door locks, the industry is shifting toward Brushless DC (BLDC) technology. Our BL2838 series offers a lifespan exceeding 10,000 hours, significantly reducing the Total Cost of Ownership (TCO) for industrial applications.
We are exploring the use of PEEK gears and advanced powder metallurgy for gearboxes to achieve "Ultra-Quiet" operation (below 35dB) for luxury automotive interiors and smart home devices.
Our 28mm gear motors are not just components; they are critical enablers for global industries. We provide tailored solutions that address specific sector pain points.
From central locking actuators (FC280 series) to rearview mirror steering, our motors are designed to withstand extreme temperatures (-40°C to 125°C) and high-vibration environments. Compliance with automotive-grade standards ensures zero-failure performance in critical safety modules.
In the smart home sector, noise and aesthetics are paramount. Our 28mm motors power automatic curtains, smart locks, and kitchen appliances with a focus on smooth startup curves and minimal acoustic signatures.
Precision is non-negotiable in medical pumps and diagnostic equipment. We offer 28mm solutions with zero-backlash gearboxes to ensure dosage accuracy and steady fluid movement.
Collaborative robots (Cobots) require high torque density. Our motors provide the necessary power-to-weight ratio for end-effectors and joint movement in small-scale logistics robots.
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.
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.
For global enterprises, the "China + 1" strategy is often discussed, but the depth of the Shenzhen motor supply chain remains unmatched. Our location allows us to source raw materials—from high-grade silicon steel to specialized lubricants—within a 50-mile radius, ensuring rapid prototyping and resilient mass production.
Efficiency Advantages: By employing fully automatic winding machines and hobbing equipment, we minimize human error and maximize consistency. This is crucial for large-scale OEM orders where a variation of 0.1mm in shaft dimensions can halt an assembly line.
Local Support, Global Reach: We understand the importance of compliance. All our products meet RoHS and REACH directives, and we provide comprehensive documentation (PPAP, IMDS) for automotive and industrial partners in Europe and North America.
A 28mm diameter provides a significant increase in torque density. While 12mm motors are excellent for ultra-compact devices, the 28mm series can handle higher loads and offers more space for robust gear stages, making it ideal for actuators requiring between 1kg.cm to 10kg.cm of continuous torque.
Absolutely. As an OEM factory, customization is our core strength. We can modify the gearbox reduction ratio (from 1:5 to 1:1000+), shaft length, flat (D-cut) positions, and even the material of the gears (plastic, brass, or steel) to meet your specific application requirements.
For standard modifications, samples are usually ready within 10-15 days. For full custom designs requiring new molds, the lead time ranges from 30 to 45 days. Mass production typically follows a 25-30 day cycle depending on volume.
Every batch undergoes rigorous testing in our Salt Spray Chamber, Constant Temperature Room, and Life Aging Machines. We also use Coordinate Measuring Machines (CMM) to ensure that every mechanical component meets the micron-level tolerances required for high-precision motion control.
Yes, both our brushed and BLDC motors are designed to be fully compatible with standard Pulse Width Modulation (PWM) controllers, allowing for precise speed and position management.
