Direct from our Dongguan automation facility to Nagoya industrial facilities: eight core machines engineered to optimize cycle times, maintain sub-millimeter copper wire tension, and maximize motor electrical efficiency.
Nagoya stands as the engineering epicenter of Japan’s Chubu Industrial Belt—a powerhouse region producing commercial fans, HVAC climate blowers, home appliances, and electric automotive sub-assemblies. Achieving the legendary Monozukuri standard demands equipment capable of micrometer precision, absolute electromagnetic symmetry, and zero-defect output.
Japanese household and commercial table fans mandate rigorous thermal endurance. Our winding machines enforce uniform tension control across wire gauges from 0.10mm to 1.20mm, completely avoiding enamel stretching and microscopic pinhole fissures that cause premature dielectric breakdown.
Purchasing directly from our factory in Qishi Town, Dongguan, circumvents Tokyo and Osaka trading house markups of 35%–55%. Plant managers in Nagoya secure heavy-duty, PLC-controlled machinery at wholesale capital expenditure while retaining custom Japanese PLC/servo compatibility.
With regular container shipping from Shenzhen/Guangzhou ports to the Port of Nagoya (Chubu gateway) spanning just 5 to 7 transit days, replacement tooling, auxiliary spare parts, and custom formers arrive with zero operational friction.
The Chubu Electric Power grid serving Nagoya operates at 60 Hz. A table fan motor calibrated for 50 Hz Eastern Japan (Tokyo/Tohoku) experiences elevated inductive reactance and flux density shifts when deployed on a 60 Hz Western grid. Our winding machine parameter controllers allow instant programmatic compensation for turn counts and slot layer packing to preserve optimal torque curves without hardware remanufacturing.
Whether manufacturing shaded-pole motors, permanent split capacitor (PSC) motors, or high-efficiency Brushless DC (BLDC) motors for low-noise circulation fans, modern winding requires seamless integration across five technological axes.
| Machine Process | Core Functionality | Applicable Motor Topologies | Critical Nagoya Quality Metric |
|---|---|---|---|
| 1. Slot Paper Insulation | Cold-folds, creases, cuts, and inserts DMD/Nomex liners into each core slot in < 0.5s per slot. | Shaded-Pole, PSC, BLDC Outrunner/Inrunner | Dielectric withstand > 1800V AC without edge tearing or flare burrs. |
| 2. Multi-Station Coil Winding | CNC dual/six flyer winding arms deliver copper/aluminum wire at speeds up to 3,500 RPM with constant tension. | 4-Pole / 6-Pole Desk Fans, Floor Circulators | Turn-to-turn insulation retention; zero wire twisting; winding resistance variation ≤ 1.2%. |
| 3. Simultaneous Wedge & Coil Insert | Transfers the wound coils and protective closure wedges directly into the stator laminations in a single vertical stroke. | High-Efficiency Table Fans, Box Fans | Zero displacement of slot liners; preserves 75%+ slot fill factor without wire shearing. |
| 4. 3D Hydraulic Coil Forming | Expands and pre-shapes both end-turns radially and axially to guarantee rotor clearance. | Compact Table Fans, Slim Air Circulators | Concentricity within 0.05mm; prevents end-turn rubbing against aluminum die-cast end shields. |
| 5. Servo-Driven Coil Lacing | Binds the end-winding bundles with high-tensile polyester cord via diamond or continuous knotting patterns. | Industrial Air Moving Units, Luxury Silent Fans | Suppression of 120Hz/240Hz mechanical vibration hum during continuous oscillation. |
| 6. Dynamic Rotor Finishing | Pneumatic diamond-lathe turning cuts rotor core stack OD to eliminate eccentricity. | Squirrel Cage Induction & IPM Rotors | Uniform electromagnetic air gap of 0.25mm ± 0.015mm, eliminating magnetic cogging. |
Our machinery is tailored to the exact requirements of Nagoya-based industrial sectors—delivering precision components for commercial, domestic, and precision cooling architectures.
Japanese consumer preferences prioritize sound levels below 28 dB(A). Our high-precision coil winding and shaping lines eliminate phase imbalance, extinguishing the harmonic hum standard in mass-market table fans.
Compact living spaces in Nagoya, Kasugai, and Okazaki necessitate high-CFM vortex air circulators. Our 6-station winding units allow heavy-gauge packing into restricted stator envelopes.
As the nerve center of Toyota City and Aichi automotive component suppliers, regional manufacturers deploy our winding equipment for 12V/24V brushless cabin ventilation and battery-cooling fans.
Heavy-duty oscillating industrial fans used throughout Chubu assembly plants require rugged SC45# motor shafts and robust 4-pole/6-pole windings that withstand thermal spikes in foundry environments.
Regulatory mandates under Japan’s revised Energy Conservation Act have intensified the shift toward high-efficiency fan motor configurations across all domestic appliance tiers.
While traditional shaded-pole desk fan motors were cheap to produce, their 30%–40% electrical efficiency is no longer viable under modern Japanese retail efficiency ratings. Nagoya factories are re-tooling for 85%+ efficient Brushless DC inner/outer stators. Our winding units are modularly configured with dual software algorithms to wind traditional AC stators and brushless multi-pole armatures on the same base machine.
High copper packing factors require high winding density without wire elongation. Machine models like the HF-LO2-6G utilize closed-loop magnetic brake damping. This prevents tension spikes during the high acceleration phases of flyer rotation, preserving the critical enamel dielectric coating demanded by Japanese electrical safety certification (PSE mark).
With seasonal fan model iterations in Japan requiring shorter production lead times, equipment must change tooling within 15 minutes. Our machine formers and inserting blades utilize CNC-machined quick-release locating pins, enabling Nagoya plants to shift from 12-slot desk fan stators to 24-slot commercial floor blower stators within a single operator shift.
Zunqi Intelligent Equipment delivers matched, fully harmonized production lines where cycle times, tooling heights, and transfer mechanisms sync seamlessly across all 8 phases.
Automatic feeding, creasing, shearing, and insertion of high-grade slot paper liners.
Dual-flyer high-speed winding of single or multi-wire strands to strict turn counts.
Servo-actuated push rods press coils and slot closure wedges into the iron core simultaneously.
Hydraulic pre-forming dies press the end-windings to clear the rotor insertion pathway.
Servo needles tie both end-turns simultaneously, providing maximum mechanical rigidity.
Final hydraulic press sizing guarantees stator end-turn height and outside diameter limits.
CNC diamond lathe tools shave the cast-aluminum rotor stack to uniform air-gap specs.
Hydraulic ram inserts the SC45# ground shaft into the heated rotor core with micron precision.
Headquartered in Qishi Town, Dongguan, Zunqi combines the speed and supply chain advantages of China’s premier manufacturing cluster with the exacting quality control demanded by global motor OEMs.
We are not a secondary broker. Our manufacturing facilities are fully verified onsite by international auditing bodies through Alibaba.com. With 17+ years of dedicated export experience, our machinery runs in premier motor plants across Europe, North America, and East Asia.
To integrate into Nagoya plant automation architectures, our electrical control cabinets can be configured with genuine Mitsubishi Electric MELSEC-Q/FX series PLCs, Omron safety relays, Panasonic servo drives, and SMC pneumatic valves for seamless maintenance.
We never ship a machine based purely on 2D drawings. Nagoya clients air-courier physical lamination stacks and copper wire samples to our factory. We custom-grind tooling, run sample trial batches, and provide 4K high-speed video acceptance data before crate dispatch.
Clear, authoritative answers addressing technical standards, lead times, electrical configurations, and after-sales support for plant engineers and sourcing managers in Japan.
Yes, absolutely. The Chubu Electric Power utility network operating throughout Nagoya operates at 200V 3-Phase at 60 Hz (with single-phase auxiliary lines at 100V 60Hz). While our standard Chinese domestic production utilizes 380V/220V 50Hz, every export machine bound for Nagoya is custom-built with transformers, variable frequency drives (VFDs), and servo motors specified for 200V/60Hz or 100V/60Hz. Voltage verification is documented in your pre-dispatch testing certificate.
Our Minimum Order Quantity (MOQ) across our entire machinery range is 1 set. For custom tooling—including tailored flyer winding arms, coil transfer magazines, and insertion push blades matched to your unique stator slot geometry—our design-and-fabrication cycle takes approximately 15 to 25 business days. We validate the tooling using your supplied stator samples in our Dongguan facility before crating.
In our Automatic Servo System Stator Coil and Wedge Inserting Machine, the inserting teeth, guide blades, and push fingers are CNC-machined from hardened high-speed tool steel (SKD11 / Cr12MoV), followed by vacuum heat treatment to HRC 58-62 and mirror micro-polishing. The push mechanism synchronizes with the wedge feed so the slot liner folds over the wire prior to final seating, preventing metal-to-metal rubbing and maintaining flawless enamel insulation integrity.
All Zunqi machines include a comprehensive 1-Year Factory Warranty covering core components (PLC, drive engine, bearings, pneumatic cylinders). In the event of an operational anomaly, our engineering desk connects via high-definition video within 9 hours. Because we utilize standardized, modular components (such as Mitsubishi, Panasonic, SMC, and Airtac), standard wear components are readily sourced within Japan, while custom-machined replacement blades ship via express air courier directly to Chubu Centrair Airport within 48 to 72 hours.
Yes. Many fan motor manufacturers transition between copper and cost-effective aluminum wire based on copper price fluctuations. Aluminum wire has lower tensile strength and a greater propensity for elongation or necking. Our winding machines feature programmable digital magnetic tensioners that allow operators to store distinct tension profiles in the PLC memory. Shifting from 0.25mm copper to 0.32mm aluminum requires simply selecting the pre-stored recipe on the touchscreen, automatically lowering initial flyer acceleration to avoid wire snap.
Every unit is treated with vapor-corrosion inhibitor (VCI) oil, vacuum-wrapped in moisture-barrier film, anchored via high-tensile steel mounting bolts to a solid timber skid, and encased in an export-grade, fumigation-free plywood crate compliant with ISPM 15 standards. Shipments depart directly from Shenzhen or Guangzhou ports to the Port of Nagoya, taking approximately 5 to 7 days of maritime transit. We provide full commercial documentation, packing lists, bill of lading, and certificates of origin for expedited Japanese customs clearance.
