Engineered directly in Dongguan by Zunqi Intelligent Equipment Co., Ltd., our machinery matches the operational envelopes, electrical constraints, and rugged performance standards required by motor assembly plants and repair workshops in Maliana and across Southeast Asia.
Why modern electric motor manufacturers and mechanical overhaul stations transition from manual cord tying to automated hook-needle single-side lacing systems.
The single-side lacing mechanism utilizes a high-carbon alloy hook needle paired with a synchronized bottom looper. Driven by an eccentric camshaft or independent servo axis, the needle pierces between coil end-turns, captures the lacing cord (polyester or Nomex), and loops it over the winding crown. Rotary indexing tables ensure pitch-to-pitch consistency with zero missed stitches.
Manual lacing inevitably produces uneven tension, resulting in loose coils that vibrate under electromagnetic torque or overtight loops that cut through slot phase paper. Our machine incorporates an adjustable mechanical friction and pneumatic damping tensioner, maintaining cord pull between 18N and 35N. This compacts the coil head securely while safeguarding copper enamel integrity.
Properly bound stator coil crowns eliminate harmonic vibration, preventing inter-turn short circuits caused by micro-abrasion of magnet wire coatings during continuous start-stop duty cycles. The consistent geometry of single-side laced end-turns promotes uniform varnish penetration and optimizes laminar cooling air flow inside electric fan and pump casings.
How our motor manufacturing and coil lacing systems support agricultural mechanization, municipal water pumping, and residential cooling infrastructure in the Bobonaro municipality.
Maliana is the primary rice and grain production hub of Timor-Leste, centered around the fertile Maliana Plain. Submersible pumps and centrifugal irrigation motors face harsh duty cycles with muddy water and high ambient temperatures. Our lacing machines secure the heavy-gauge copper windings of 0.75kW to 3.7kW agricultural water pumps, preventing coil displacement under sudden hydraulic load swings.
Due to logistics lead times from Dili and overseas ports, local agro-processing enterprises and utility repair depots in Maliana prioritize rebuilding burned-out stators over importing complete replacement motors. Introducing semi-automatic single-side coil lacing reduces rewinding turnaround time from hours to under two minutes per stator, restoring factory-grade mechanical stability.
Tropical heat requires ubiquitous table fans, ceiling fans, and exhaust blowers in homes, commercial spaces, and processing facilities. Our HF-R40-2C winding machine and HF single-side lacing unit handle standard 8-pole and 16-pole fan stators. They streamline localized assembly and component refurbishing, significantly lowering consumer retail and maintenance costs.
Automatic paper feeding, creasing, cutting, and slot lining to prevent phase-to-ground dielectric failure.
Single or multi-station winders load copper or aluminum magnet wire into precise coil groups with digital turn count.
Wound coils and insulating top wedges are pushed into lamination core slots simultaneously in a single stroke.
Expanding internal mandrel and outer hydraulic jaws pre-shape end-turns to clear the rotor clearance bore.
Automated needle mechanism binds end windings with high-strength cord, securing leads and end geometry.
Secondary forming press sizes coil head exterior envelope to strictly match motor frame and end-bell housings.
Lathe tool faces the rotor lamination OD, maintaining exact air-gap tolerances (0.25mm - 0.45mm) without burrs.
Controlled hydraulic press fits SC45# motor shafts into the rotor core with monitored tonnage and concentricity.

Navigating grid stabilization, decentralized mechanical assembly, and sustainable equipment sourcing along the Timor-Leste western corridor.
Maliana's grid infrastructure, supplied via transmission links from Betano and regional substations, experiences load shifts during peak agricultural milling seasons. Equipment deployed in local workshops must withstand voltage fluctuations between 190V and 245V on single-phase lines. Our machines integrate heavy-duty copper-wound transformers and industrial relays to prevent nuisance tripping during sudden line drops.
Local government policies actively encourage domestic rice processing, maize drying, and coffee pulping within Bobonaro rather than exporting raw commodities. This macro shift creates sustained demand for durable electric motors driving threshers, dehullers, and blowers. Establishing localized stator rewinding and small-batch production reduces regional downtime and equipment dependency on overseas spares.
Timor-Leste's tropical monsoonal climate presents humidity levels exceeding 85% during wet seasons, accelerating atmospheric corrosion on exposed metal tooling and electrical contacts. Zunqi applies electroplated anti-rust coatings to machine guides, cam gears, and fixtures, housing all PLC logic in sealed IP54-rated electrical enclosures with heat-dissipating cooling fans.
Headquartered in Qishi Town, Dongguan, Guangdong, China — delivering specialized motor stator and rotor manufacturing automation for over 17 years.
Every motor core has unique slot geometry, stack height, and tooth curvature.

Shipments depart from Shenzhen or Guangzhou ports directly to the Port of Dili (Tibai Port) via feeder vessels calling through Singapore or Surabaya. Ocean transit to Dili typically takes 18 to 26 days. From Dili, road transport westward to Maliana (Bobonaro Municipality) takes approximately 4 to 6 hours over the renovated coastal and inland highway. We provide complete commercial invoices, packing lists, and export certificates of origin for customs clearance.
Yes. Timor-Leste's standard public distribution is 220V single-phase / 380V-400V three-phase at 50Hz. The HF Single Side Lacing Machine can be ordered with either a 1000W 220V 50Hz single-phase drive or a 380V three-phase motor. For facilities relying on diesel or solar generator mini-grids, we equip the control system with wide-tolerance electromagnetic contactors to ensure reliable operation despite frequency jitter.
To fabricate the clamping fixture, hook needle height, and indexing cam:
1. Stator outer diameter (OD) and inner bore diameter (ID).
2. Lamination stack height (core thickness).
3. Total slot count (e.g., 8, 16, 24, 36 slots).
4. Magnet wire diameter (enamelled copper or aluminum) and coil head protrusion height.
Sending a mechanical 2D/3D CAD drawing or couriering an un-wound stator sample ensures exact tolerance verification.
Yes. While agricultural pump motors in Maliana predominantly utilize enamelled copper wire for maximum efficiency, many table fans and economy ceiling fan motors use aluminum or copper-clad aluminum (CCA) magnet wire.
