Jershtech DC Motors
Explore our highly integrated motor designs manufactured for automotive, medical, and specialized industrial automation applications.
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.
Our engineering expertise extends to optimizing high-power density motors frequently deployed in hydraulic micro-power units, compact lift valves, and rugged actuators. By analyzing the dynamic load curves of hydraulic applications, our design team enhances key parameters—such as peak starting torque and thermal dissipation—ensuring long-term operational resilience under extreme industrial environments.
Addressing the shifting paradigm from traditional high-friction brushed solutions to smart, brushless direct-drive hydraulics.
The industrial hydraulic landscape is undergoing a critical transition. Traditionally, micro-hydraulic power packs relied on standard brushed DC motors (typically 12V, 24V, or 48V PMDC) to drive fluid pumps in short duty cycles (S2/S3 rating). However, modern material handling, mobile machinery, and automotive systems demand high duty cycles, continuous speed control, and maintenance-free operation. This is where Brushless DC (BLDC) technology steps in.
By employing high-remanence Neodymium (NdFeB) permanent magnets instead of conventional Ferrite, our newer generations of DC motors shrink the physical footprint by up to 35% while maintaining the equivalent starting torque. This is particularly vital for compact hydraulic units where space is at a premium but high initial breakout torque is required to overcome system pressure.
Future iterations of hydraulic DC motor systems integrate the motor driver and pump interface directly onto the rear end-bell of the motor housing. This configuration minimizes electromagnetic interference (EMI), eliminates extensive external wiring, and supports smart communication protocols like CAN bus, MODBUS, or LIN bus. Real-time feedback on temperature, current draw, and rotational speed enables predictive maintenance for the hydraulic pump assembly.
| Motor Architecture | Efficiency Range | Thermal Profile | Typical Duty Cycle | Key Advantages in Hydraulics |
|---|---|---|---|---|
| Permanent Magnet Brushed (PMDC) | 70% - 82% | High heat build-up at brushes | S2 (Intermittent 5-10 min) | Low cost, simple two-wire connection, high starting torque. |
| Brushless DC (BLDC) Standard | 85% - 92% | Excellent thermal transfer via stator | S1 (Continuous duty) | Long lifespan, zero carbon dust, spark-free (safe in chemical environments). |
| Sensorless BLDC (High-Tech) | 88% - 94% | Optimized via vector control (FOC) | S1 / S3 continuous cycle | Extremely compact, highly resistant to moisture/vibration, variable speed. |
Inside Shenzhen Jershtech's production floor—leveraging automated fabrication to secure strict dimensional tolerances and scale economies.
Deploying robust electrical architectures across key global industries requiring high pressure, extreme loads, and continuous precision.
From hydraulic tailgates and cargo lift ramps to precision power steering assist systems in special utility vehicles, our high-torque 12V and 24V DC motors deliver instantaneous power. The mechanical interface is engineered for simple spline coupling, standard SAE pumps, or customized integrated tang drives to prevent alignment failures.
Scissor lifts, pallet jacks, and miniature dock levelers utilize our DC gear motors and custom high-torque motors to drive hydraulic fluid displacement loops. By utilizing high-grade copper wire insulation (Class H, up to 180°C) and robust carbon brushes, these motors withstand short-duration high-load spikes without thermal degradation.
As micro-actuation advances, N20 gear motors and compact high-speed brushless motors (such as the BL2929F) provide exact speed and torque vectors. These systems are used in smart lock mechanisms, medical devices, robotic arms, and complex consumer electronics where failure is not an option.
True engineering reliability is proven in the lab. We validate every parameter to meet strict IEC, CE, and global industrial mandates.
Our quality verification processes ensure that shaft runouts, mechanical vibration levels, sound intensity (measured inside our specialized Soundproof Room), and environmental seals (tested via Constant Temperature and Humidity Chambers) align perfectly with client technical draws. In-house CMM measurements ensure precision down to the micron, making Jershtech a trusted long-term OEM/ODM partner.
Navigating the complex technical requirements of custom motor manufacturing requires more than just high-quality hardware. It requires absolute reliability in international supply logistics, trade compliance, and deep local support.
All motor solutions leaving our Shenzhen factory conform to internationally recognized standards including CE, RoHS, and REACH. In addition, our manufacturing facilities adhere to strict ISO 9001:2015 quality management certifications, facilitating seamless integration into projects destined for North American, European, and Asia-Pacific markets.
From initial rapid-prototype runs using precise automated wire-winding setups to high-volume manufacturing, our engineers work directly with your research & development teams. We provide 3D CAD modeling, custom-shaft options, tailored terminal arrangements, and dynamic load simulation data before hard tooling commences.
By keeping core processes like toolmaking, precision gear hobbing, and electrical assembly in-house, we mitigate the risk of sub-tier component delays. Our strategic localization in Shenzhen, the tech manufacturing heart of China, allows us to secure raw materials (such as pure copper wire and rare-earth magnets) at stable pricing, insulating our B2B procurement partners from market volatility.
Whether you require ex-works (EXW), FOB, or DDP shipments, Jershtech ensures secure, moisture-controlled protective packaging to maintain pristine stator and commutator integrity across ocean transit.
