OEM Automatic Stator Winding, Lacing & Assembling Equipment
Streamlined turnkey equipment specifically configured to meet European CE standards, standard 400V/50Hz grid specifications, and high-duty continuous operation across manufacturing hubs in Skopje, Bitola, Prilep, and Tetovo.
Stator Coil Lacing Kinematics & Mechanical Integrity in Modern Motors
Automated coil lacing is far more than a cosmetic bundling step. It is the definitive phase that dictates mechanical resistance against electromagnetic harmonic vibration, thermal expansion shock, and partial discharge failure.
Dynamic Cord Tensioning
Unlike manual tying where human fatigue causes varying cord tensions (from 8N to over 35N), our servo-controlled lacing needles maintain a steady, uniform tension (programmable between 12N to 22N ±1N). This completely prevents micro-abrasions on the magnet wire enameled coating while eliminating copper loose slack.
Simultaneous Dual-Head Indexing
Equipped with dual hooked lacing needles actuated by dual servo axes, our automatic double-side machines lace both upper and lower coil overhangs simultaneously. Cycle times drop from over 180 seconds in manual operations to under 14 seconds for a standard 24-slot stator core.
Thermal & Dielectric Security
By securing intermediate phase insulation papers tightly against phase winding boundaries, automated lacing eliminates air voids. This tight compaction drastically increases varnish resin uptake during vacuum pressure impregnation (VPI) and prevents phase-to-phase shorts under high thermal stress.

| Insulation Film Damage Risk | High (Friction from hand tools) | Medium (Standard guides) | < 0.002% (Polished ceramic eyes) | Drastically lowers partial discharge rates |
| Phase Paper Stability | Prone to displacement | Good alignment | Pre-clamped during needle stroke | Meets high dielectric breakdown thresholds |
Industrial Applications Across North Macedonia's Manufacturing Zones
North Macedonia is rapidly establishing itself as a strategic Southeastern European nearshoring hub. Driven by substantial industrial expansion within the Technological Industrial Development Zones (TIDZ), our machinery meets the exacting demands of regional OEM operations.
Automotive Actuators & Auxiliary Motors
Suppliers located in TIDZ Skopje 1 (Bunardzik) and TIDZ Tetovo manufacturing brushless DC (BLDC) motors, cooling fans, and seat adjustment drives for major European automotive brands rely on micron-level stator repeatability and complete traceable parameter logging.
Industrial Water Pumps & Agricultural Irrigation
From submersible drainage pumps to agricultural water distribution across the Vardar River basin, motor stators must withstand continuous duty in humid, thermally demanding conditions. Automated lacing ensures end-turns stay bonded under extreme torque spikes.
Commercial HVAC & Industrial Exhaust Systems
Producers of heavy-duty ventilation fans, refrigeration compressors, and heat pump blowers in Bitola, Prilep, and Kumanovo require custom-tooled lacing machines capable of handling variable stator stack heights from 20 mm up to 180 mm without tedious mechanical changeovers.
Trends Transforming Electric Motor Manufacturing in North Macedonia
Key macro factors driving motor manufacturers in the Western Balkans to modernize from manual winding tables to integrated CNC stator manufacturing cells.
EU Nearshoring Influx
German, Austrian, and Italian tier-1 OEMs are shifting supply chains closer to continental borders. Stator production facilities in North Macedonia must match European quality certifications to secure long-term purchase agreements.
Rising Labor Competitiveness
As regional industrial wages steadily rise across the Western Balkans, relying on labor-intensive manual coil tying leads to unsustainable unit costs. Automated lacing eliminates manual bottlenecks and allows a single operator to supervise four lines.
Transition to IE3/IE4 Motors
Stricter European energy efficiency mandates dictate that motor stators achieve higher slot fill factors. Automated coil insertion and precise end-turn forming are mandatory to accommodate increased copper cross-sections without short-circuiting.
Digital Traceability
Modern quality auditing requires real-time parameter tracking. Our machines feature industrial Ethernet interfaces (Modbus, Profinet) that feed lacing tensions, speed, and count data directly to plant-wide MES systems.
Direct Manufacturer Capabilities & Engineering Assurance
Operating out of Dongguan’s world-renowned hardware and motor manufacturing core, Zunqi brings 17+ years of dedicated export experience, offering direct factory engineering pricing with robust Western industrial reliability.

Video Factory Acceptance (FAT)
Prior to packing, your actual stator samples and enameled wires are tested on the completed machine. We provide high-definition, multi-angle trial videos and parameter sign-off sheets.
Zero-Moisture Export Crating
Machines bound for European and Balkan destinations are treated with heavy VCI anti-rust oil, heat-sealed in vacuum-barrier foil, and bolted inside fumigation-free solid plywood sea cases.
Frequently Asked Questions by North Macedonia Buyers
Practical engineering, electrical compatibility, customs clearance, and spare parts insights for operations managers and procurement engineers in North Macedonia.
Are Zunqi stator lacing and winding machines compatible with North Macedonia’s electrical grid?
Yes, absolutely. The electrical power distribution across North Macedonia operates on a standard 400V 3-phase (±10%) at 50Hz, with single-phase lines at 230V 50Hz (TN-S/TN-C-S earthing configurations). Our machinery is built to order with matched transformers, CE-certified servo drives, and Siemens or Mitsubishi PLCs tuned directly for 400V 3-phase 50Hz industrial mains, eliminating any need for local external phase converters or aftermarket transformers.
What is the typical shipping route and customs clearance protocol for machinery arriving in North Macedonia?
As North Macedonia is landlocked, containerized sea freight typically dispatches from Shenzhen or Guangzhou port directly to the Port of Thessaloniki (Greece) or the Port of Durrës (Albania). From Thessaloniki, transit via bonded freight rail or road carrier directly through the Bogorodica/Evzoni border crossing into Skopje or your designated TIDZ free zone takes merely 1 to 2 business days. We provide comprehensive export documentation, including full Bill of Lading, Commercial Invoice, Packing List with accurate HS Code classifications (typically under 8479.81 or 8479.89), and Certificate of Origin to streamline clearance through the Customs Administration of North Macedonia (Carina).
Can a single stator lacing machine accommodate multiple motor frame sizes and slot counts?
Yes. Our automatic stator coil lacing machines feature modular, quick-changeover mechanical tooling fixtures. Stator stack height adjustments (e.g., from 30 mm to 120 mm) are electronically set via the HMI touchscreen by altering the servo needle's vertical stroke limit. If you produce motors with distinct outer diameters (OD) or inner diameters (ID), you only need to swap the precision locating cup and push-rod assembly, which takes less than 20 minutes for a trained technician.
What lacing cords and needle threads can be utilized?
Our feed mechanisms and needle eyelets are optimized for heavy-duty industrial polyester lacing cords, braided nylon twine, and Nomex-compatible high-temperature ties ranging from 0.8 mm up to 2.2 mm in thickness. The wire tensioner and pneumatic cord-cutting scissor unit can be dialed in to ensure a neat, fray-free cut after the automated end knot is formed.
How does Zunqi provide installation, training, and warranty support in North Macedonia?
Every machine is covered by a 1-year comprehensive warranty on all structural, electrical, and pneumatic assemblies. Prior to shipment, we provide exhaustive wiring schematics, English-language HMI interfaces, and step-by-step video setup guides. Our senior application engineers provide remote commissioning support via video link within 9 hours. For turnkey line installations in major industrial facilities across Skopje or Bitola, on-site commissioning and operator training engineers can be dispatched upon request.
How quickly can replacement wear parts (needles, knives, guide fingers) be delivered?
We supply a complete 1-to-2-year consumable wear-and-tear kit inside the wooden crate with every machine, which includes extra tungsten-carbide lacing needles, hooking fingers, cord-cutting blades, springs, and pneumatic cylinders. For emergency reorders, standard replacement components are dispatched via DHL/FedEx International Express, reaching Skopje International Airport within 3 to 5 business days.
