Jershtech DC Motors
High-efficiency, dust-sealed, and heavy-torque 36mm planetary and spur micro gear motors optimized for Southern Africa's demanding mechanical layouts.
Namibia is rapidly positioning itself as a key logistics and industrial hub within the Southern African Development Community (SADC). With massive investments flowing into the Erongo region's uranium mining operations, deep-sea diamond extraction, utility-scale solar photovoltaic tracking systems in Otjozondjupa, and automated drip irrigation grids in the Hardap region, the need for robust motion control components is at an all-time high.
In these challenging environments, standard electric motors face high failure rates. The combination of intense ultraviolet radiation, fine airborne silica dust from the Namib desert, and high ambient temperatures exceeding 45°C requires specialized engineering. This is where the 36mm DC Planetary Gear Motor becomes essential.
By offering superior power density, high radial load bearing, and a compact outer diameter, our 36mm drive systems are engineered specifically to overcome these environmental and mechanical hurdles, delivering sustained uptime where off-grid operations depend on failure-proof components.
Windblown sand in coastal Walvis Bay and inland mining corridors requires IP65 or higher planetary gearboxes. Sealed ball bearings and specialized nitrile shaft seals prevent gear train contamination.
Continuous outdoor operation requires high-temperature class H magnet wire and heat-dissipating anodized aluminum alloy housings to prevent thermal runaway.
Remote operations rely on 12V or 24V battery systems charged by solar power. Highly efficient BLDC planetary gear motors maximize torque output per watt, preserving battery life.
Shenzhen Jershtech Technology Co., Ltd. bridges the gap between advanced manufacturing efficiency and global B2B 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 our clients in Namibia, we provide end-to-end export support, shipping directly to the Port of Walvis Bay and handling cross-border logistics smoothly. This ensures that major mines, agricultural centers, and infrastructure projects receive their custom drive assemblies on time and built to exact specifications.
Our manufacturing facility is equipped with automated winding systems, CNC hobbing machines, and highly accurate coordinate measuring equipment. Every 36mm gear motor production batch undergoes dynamic balance tests, noise analysis in soundproof chambers, and life-aging simulations to guarantee compliance with international CE, RoHS, and IEC standards.
Understanding the mathematical and structural differences to maximize efficiency and minimize gear train failures in high-load setups.
Planetary gearboxes route power through three or four planet gears rotating around a central sun gear, all encased within an outer ring gear. This configuration shares the mechanical loads across multiple teeth, providing high torque capacity in a small overall footprint.
For Namibia's heavy-duty industrial valves and solar tracking systems, planetary gearboxes offer high torsional stiffness and minimal backlash. However, they generate slightly higher friction than spur gears. To offset this, we use premium synthetic lubrication to keep temperatures low in warm climates.
Spur gearboxes transfer rotation via parallel shafts using straight-toothed gears. These systems are simple, highly efficient, and cost-effective, making them well-suited for light-to-medium loads where budget constraints are a priority.
Because the load is concentrated on a single gear tooth contact point, spur gear motors are best for applications with minimal axial and radial forces, such as smart home locks, retail display stands, and precision lab equipment.

How our exported 36mm gear motors integrate into local commercial and industrial sectors.
From the uranium fields in Erongo to gold mining operations near Karibib, 36mm high-torque brushless planetary motors are used to drive conveyor divert valves, automated sorting flaps, and core analysis equipment. Their steel gear trains handle continuous shock loads without tooth shearing.
Namibia's high solar irradiance index makes solar energy highly viable. Our high-torque 36mm planetary gearboxes are built with ratios up to 720:1, providing the torque density needed to slowly steer heavy solar panels throughout the day while resisting high wind loads.
In areas like the Hardap region, automated farming setups use our 36mm DC gear motors to actuate high-pressure agricultural ball valves. Their high starting torque easily breaks through scale buildup in water pipes, protecting crops from irrigation system blockages.
We understand the logistical requirements of shipping critical industrial components to Southern Africa. Our export workflows are optimized to deliver hardware directly to your site, reducing import-related delays.
To provide reliable gear motors, Jershtech uses premium materials throughout the production process:
Rare-Earth Neodymium Magnets: NdFeB magnets provide high magnetic flux density, allowing for a compact motor design without sacrificing power output.
High-Grade Carbon & Copper Carbon Brushes: For our brushed DC variants, we use high-wear-resistance brushes to extend operational life and reduce maintenance requirements.
Hardened Steel Gear Sets: Unlike plastic gears that fail under load, our 36mm planetary gearboxes use precision-cut steel gears to handle peak torque demands without failure.
Engineered for versatile industrial roles, these models provide reliable performance across a range of applications.
Highly specialized, miniature, and high-speed motion systems engineered to meet advanced medical, robotic, and precision hardware specifications.
The shift from standard analog DC motors to integrated smart actuators with closed-loop communication protocols.
Integrating high-resolution magnetic and optical encoders into the rear shaft of the 36mm BLDC motor. This provides real-time position and velocity feedback, which is essential for solar tracking arrays and industrial pick-and-place robotics.
Eliminating external motor driver boards by embedding CAN bus, RS-485, and Modbus communication protocols directly into the motor end-bell. This simplifies system wiring and improves electromagnetic compatibility (EMC) in heavy industrial machinery.
Adding embedded thermal sensors and current monitoring diagnostics. By tracking deviations in temperature and current draw, the system can flag potential mechanical issues before a failure occurs, helping to minimize downtime in remote locations.
Answers to common technical, logistics, and customization questions from engineering and procurement managers.
A: For standard models, production takes approximately 15 to 20 days, while custom shaft or gear ratios require 25 to 30 days. Standard shipping from Shenzhen goes via ocean freight to the Port of Walvis Bay, taking about 30 to 35 days. For urgent requirements, air freight to Hosea Kutako International Airport (WDH) in Windhoek can deliver components in 5 to 7 business days.
A: Our planetary gearboxes can be customized with double-lip nitrile rubber (NBR) or fluororubber (FKM) shaft seals. The motor housing is sealed with O-rings, and wire outlets are protected with liquid-tight cable glands. This achieves an IP65 or IP67 ingress protection rating, preventing fine silica dust from entering the gear assembly or motor windings.
A: Brushed DC motors rely on carbon brushes that wear down over time, requiring periodic inspection and replacement. Brushless (BLDC) motors eliminate these wearing components, extending their operational life to over 20,000 hours. This makes BLDC motors highly suited for remote, difficult-to-access installations where minimizing field maintenance is critical.
A: Yes, we offer extensive customization options for output shafts. We can modify shaft lengths, machine D-flats, cut keyways, machine cross-drilled holes, or cut external threads. Custom shaft materials, such as high-tensile SUS303/SUS304 stainless steel, are also available for coastal applications exposed to salt mist.
A: We provide all standard documentation required for export, including a Certificate of Origin, detailed commercial invoice with HS codes (typically 8501.10 for micro motors), and complete packing lists. Our logistics team works with your designated clearing agents to ensure smooth clearance at the Namibian border.
