Jershtech DC Motors
Direct from Jershtech Shenzhen: Specialized drive configurations engineered to deliver maximum starting torque, high efficiency, and custom gear integration.
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.
In today's hyper-automated market, the demand for reliable, cost-efficient brush motors remains strong. While brushless variants (BLDC) capture industry mindshare, brushed permanent magnet DC (PMDC) systems continue to dominate applications requiring robust start-up torque, simplified control electronics, and lower overall system costs.
The central challenge for international buyers is navigating the variations in manufacturing tolerances, quality drift, and material compliance among suppliers. Jershtech eliminates these friction points by combining state-of-the-art testing equipment with automated manufacturing processes. This approach ensures consistent batch quality and complete compliance with European and North American environmental directives.

Jershtech is actively testing and transitioning to custom carbon-copper composite brushes and advanced synthetic lubricants. This technology roadmap aims to increase the operating life of standard PMDC brush configurations by up to 40%, meeting the demands of modern industrial actuators without the higher cost of brushless conversions.
The Shenzhen-Dongguan industrial corridor provides an efficient ecosystem for electromagnetic motor production. Jershtech leverages this ecosystem to secure raw materials—such as high-grade electrical steel, high-purity copper magnet wire, and rare-earth NdFeB magnets—quickly and cost-effectively.
We operate fully automated winding, pressing, and testing lines. This reduces our reliance on manual labor, ensures consistent assembly tolerances, and maintains competitive B2B pricing.
Additionally, our proximity to the Port of Shenzhen simplifies global logistics, ensuring reliable and cost-effective shipping routes to international ports.
Spectrometer checks on copper alloys and magnetic permeability tests on iron laminations.
Automated shaft deflection monitoring and winding tension control during production.
100% testing of noise levels in our anechoic room and comprehensive electrical performance checks.

The lifespan is primarily determined by brush wear, electrical arcing, and bearing friction. Under nominal operating conditions, our precious metal brush systems achieve between 1,500 and 3,000 hours of continuous operation. The lifespan can be optimized by reducing the source voltage, using carbon-brush replacements, or adding EMI suppression circuits (varistors/capacitors) to limit brush arcing.
Our engineering team uses CAD software to customize shaft configurations (D-cut, round, splined, or threaded), modify gear ratios on planetary/spur gearboxes, and adjust winding configurations to meet specific torque-speed targets. Our minimum order quantity (MOQ) for custom runs typically ranges from 1,000 to 5,000 units, depending on the complexity of the tooling updates.
Yes. All raw materials used in our factory—including copper windings, rotor cores, commutators, and magnet alloys—are audited to ensure full compliance with EU RoHS and REACH directives. We maintain updated material declaration sheets (MDS) and provide certificates of compliance with every export batch.
We mitigate quality drift through automated manufacturing lines and strict statistical process control (SPC). Critical steps—such as commutator slotting, armature winding, and balancing—are performed by automated machinery. In addition, our QC team uses Coordinate Measuring Machines (CMM) and comprehensive electrical testers to catch dimensional and electrical deviations before shipment.
