Constructed with high-grade structural alloys, precision CNC ground fly-arms, Mitsubishi/Siemens/Delta PLC architectures, and dual-station modularity. Each system is calibrated for slot-fill density, high tension consistency, and continuous duty cycles.
The port city of Wonsan represents an essential hub for maritime transit, fishing fleet logistical maintenance, ship repair yards, railway engineering, and expanding light-industrial infrastructure. Operating within coastal marine conditions presents severe operational bottlenecks for electric machinery. Elevated relative humidity, saline atmospheric exposure, and heavy cyclical loads necessitate electric motors with dense, void-free winding, robust slot insulation, and rigid mechanical stabilization.
As a leading Chinese designer and exporter of automated motor machinery, Zunqi Intelligent Equipment delivers turn-key winding, inserting, forming, and shaft-pressing solutions designed to handle both heavy-duty marine traction stators and commercial consumer motor lines. Our systems bridge the gap between expensive European automated lines and inconsistent manual winding setups, ensuring repeatable precision, minimal wire elongation, and zero dielectric enamel scratching.
By leveraging intelligent tension controllers, CNC servo flyers, and high-frequency lacing kinematics, our machines achieve slot-fill factors exceeding 78%, vital for heat mitigation in enclosed marine pump drives, cargo winches, ventilation turbines, and coastal refrigeration compressors.
Armature winding lines for heavy slip-ring motors and high-torque direct current (DC) traction systems used in wharf container gantry systems and dry-dock capstans.
Submersible pump stator automation using water-resistant slot liner insulation inserting and dual-side lacing, preventing salt-spray phase short circuits.
Multi-spindle ceiling fan, external rotor axial fan, and hermetic compressor motor stator lines guaranteeing 24/7 continuous duty at coastal chilling plants.

Understanding the transition from obsolete manual motor winding to semi-automated and fully automated manufacturing cells.
Older manual rewinding plants frequently suffer from insulation breakdown due to uneven human wire placement and surface scrapes on the polyester-imide coating. Transitioning to automated slot cell inserters and mechanical coil transfer mandrels eliminates manual friction damage. Slot liners are cut and hemmed with high edge accuracy, creating a sealed electrical barrier that withstands continuous condensing moisture and airborne chlorides common along the eastern coastal shelf.
Fluctuating raw copper availability encourages regional motor factories to introduce hybrid production lines capable of winding high-grade electrical aluminum wire alongside standard electrolytic copper. Zunqi winders feature micro-adjustable magnetic hysteresis tension pulleys and ceramic wire guides that prevent surface stretching of soft aluminum conductors, maintaining accurate circular cross-sections and predictable resistance values without breaking wire runs.
Regional modernization directives prioritize higher motor efficiency classes (IE2 to IE3 equivalents) across industrial utility fleets, industrial blowers, and port conveyers. Achieving higher efficiency ratings within restricted lamination frame sizes demands tighter winding packing factors, precise turns-per-coil counts, and minimal end-turn wire overhang. Automated CNC winding and forming machines ensure tight winding dimensions, reducing idle copper resistance loss (I²R) by up to 14%.
Located in the heart of Qishi Town, Dongguan, China's core electro-mechanical manufacturing epicenter, we deliver robust industrial automation supported by 17 years of specialized export integrity.
Tooling plates, inserting blades, and wire pushers are custom-machined from hardened SKD11 tool steel, precisely matched to your supplied stator stamping laminations.
Control panels incorporate accessible, industrial-grade PLCs, Weinview touchscreens, and Schneider electrics, ensuring local electrical technicians can easily manage maintenance.
Prior to export packaging, every machine runs test trials using customer-supplied stator stacks and wire samples. Full-length video validation is supplied before container loading.
Equipment is treated with thick VCI vapor-corrosion inhibitors, vacuum-sealed in multi-layer foil moisture barriers, and crated in solid fumigation-free hardwood cases for maritime freight.
Answers to common technical, electrical, and commercial questions from plant directors and procurement teams.
Yes. While standard machines are configured for single-phase 220V or three-phase 380V (50Hz), our power distribution units can be specified with wide-tolerance input power transformers (±15% voltage margin) and high-attenuation line filters. This prevents PLC controller lockups or servo drive position faults caused by grid spikes or inductive load drops from neighboring shipyard machinery.
Before initiating machine build, buyers send their CAD drawing files (DWG/DXF/STEP) along with critical motor parameters: stator outer diameter (OD), inner diameter (ID), stack height, slot dimensions, wire gauge, and winding schema. For highest accuracy, customers ship 5 to 10 sample lamination packs to our Dongguan facility, allowing us to machine-cut and test-fit tooling blades, guides, and transfer fingers before delivery.
We provide comprehensive digital commissioning support. Every machine is supplied with step-by-step video manuals covering uncrating, physical leveling, wire path threading, tension gauge zeroing, and touch-screen parameter inputs. All PLC interfaces feature clear, multi-language displays. If line issues emerge, our engineering team responds within 9 hours with annotated diagnostic videos and calibration guides.
Yes. Critical mechanical high-wear items—such as tungsten-carbide wire guide nozzles, inserting push fingers, wedge cutter blades, and pneumatic air seals—are kept in regular stock. Every machine order includes a comprehensive consumable spare kit with the shipment, covering typical operating needs for 1 to 2 years.
Yes. Models such as the HF-LO2-6G and our semi-automatic multi-head winders can be equipped with dual or triple pay-off stands and combined tensioner blocks. This enables parallel winding of two or more conductors simultaneously, essential for reducing skin effect in higher-frequency motors or achieving high copper cross-sectional areas in compact slot configurations.
The MOQ for our machinery is 1 set. For standard standalone winders (such as the HF-R40 ceiling fan winder or HF-BS20 lacing machine), production time is typically 15 to 20 working days. For complete integrated stator lines (insulating, winding, inserting, forming, lacing, rotor turning, shaft pressing), build and tooling calibration requires 30 to 45 working days prior to final acceptance and crating.
Send your stator and armature engineering drawings, required wire diameters, and daily target capacity. Our Dongguan technical center will configure an optimized machine proposal and complete tooling quotation within 9 business hours.
