From single-phase industrial pump stators to high-torque hairpin EV windings and core electrical components, our certified systems empower Songkhla and Southern Thailand electrical OEMs with maximum operational uptime.
Manufacturing three-phase induction and BLDC motors in Hat Yai presents unique thermodynamic and environmental challenges. Ningbo Nakro re-engineers coil insertion tooling specifically for Songkhla's tropical manufacturing parameters.
Hat Yai experiences ambient relative humidity regularly surpassing 85%, causing hygroscopic expansion and friction fluctuations in Nomex, DMD, and polyester insulation paper. Our servo-driven pushers adjust wedge feeding forces adaptively to eliminate wedge jams and delamination tearing entirely.
The core economy of Songkhla demands heavy-duty electric motors driving latex centrifuges, sheet rubber calenders, and palm oil processing pumps. Our stator inserting systems support copper wire slot fills up to 82%, accommodating thick multi-strand coils without scratching exterior enamel.
Positioned strategically within the Indonesia-Malaysia-Thailand Growth Triangle (IMT-GT), Hat Yai manufacturing hubs require rapid changeover between domestic Thai 380V/50Hz grid setups and export market configurations. Our PLC recipe management stores up to 250 stator stack variations.

How modernization policies, Southern Economic Corridor (SEC) initiatives, and cross-border clean logistics are reshaping capital equipment investments across regional plants.
With Thailand's Department of Alternative Energy Development and Efficiency (DEDE) enforcing tighter MEPs (Minimum Energy Performance Standards), motor rewinding and OEM plants in Hat Yai must eliminate manual coil beating and irregular slot fills. Automated inserting machines ensure geometric uniformity, reducing stray load losses by up to 28%.
Hat Yai functions as the pivotal overland distribution gateway between Bangkok, Penang, and Kuala Lumpur. The electrification of light commercial delivery fleets, three-wheeled passenger tuk-tuks, and port cargo handling tractors in Songkhla Port demands local supply chains for outer-rotor BLDC wheel hubs and permanent magnet stators.
Experienced motor rewinding master technicians across Southern Thailand are aging, while manual insertion of heavy-gauge wires leads to high operator fatigue and fluctuating quality. Nakro's turnkey inserting machinery replaces tedious manual wire wedging with a single push-button cycle, operable by semi-skilled line operators.
Over 14 years of dedicated electromechanical innovation, exporting heavy-duty winding and inserting lines to over 50 countries from our 30,000+ m² ISO 9001-certified industrial campus.
Founded in 2010, Nakro has developed deep domain expertise in single-phase, three-phase, BLDC, and hairpin motor production lines, offering proven equipment reliability across international export markets.
We supply more than stand-alone inserters. We supply comprehensive automated cells: insulation paper shooting, automated coil winding, wedge insertion, intermediate forming, lacing, and end-of-line electrical testing.
Nakro is your single-source supplier. Access matching commutators, 608ZZ precision bearings, carbon brushes, N52 neodymium magnets, and insulation paper designed precisely for machine tooling tolerances.
No machine ships unverified. Every stator inserting unit undergoes a strict 100% factory acceptance test using your actual lamination stacks, wire gauge, and slot insulation papers, documented via comprehensive run-off video.
Critical engineering, logistical, and commercial inquiries answered for plant directors and procurement teams in Songkhla and nationwide across Thailand.
Our stator coil inserting machines utilize a synchronous dual-push mechanism engineered specifically to safeguard wire insulation. The copper coils and the slot wedges are pushed simultaneously from opposite or synchronized axes through precision-ground guiding blades made of hardened chromium alloy steel (HRC 60-62).
The insertion blade guides maintain slot paper opening widths without scoring the enameled coating. Additionally, our servo insertion control monitors real-time thrust pressure; if an unexpected resistance peak is sensed (such as cross-wire crowding), the machine stops automatically in milliseconds to prevent wire stretching or dielectric breakdown.
Yes. Our machines are designed with modular tooling systems. Changing between different stack heights (for example, from 45 mm to 110 mm) within the same stator outer diameter takes less than 15 minutes via quick-release spacer rings and programmable servo stroke adjustments on the HMI touchscreen.
For stators with different slot configurations (e.g., transitioning from a 24-slot pump stator to a 36-slot induction motor), our complete quick-change insertion tooling module (including push blades, wedge guide magazines, and stator fixtures) can be fully swapped and calibrated within 25 to 35 minutes, eliminating lengthy production downtimes.
Our standard export machinery for Thailand is built natively for 3-Phase 380V ±10% at 50Hz, compatible with the Provincial Electricity Authority (PEA) industrial power distribution network across Hat Yai and Songkhla. Control circuits operate safely on regulated 24V DC.
The pneumatic requirements entail clean, dry compressed air at 0.5 to 0.7 MPa. We include high-performance air filtration and moisture water-separators with every machine to protect pneumatic solenoid valves against Southern Thailand's high ambient humidity levels.
Standard machines are built and factory-tested within 30 to 45 business days upon drawing approval. Custom-tooled turnkey lines require approximately 60 to 75 days. Shipping directly from Ningbo Port to Bangkok (Laem Chabang) typically takes 7 to 10 days by sea freight, followed by 1 to 2 days overland transit directly to Hat Yai.
Alternatively, feeder connections directly to Songkhla Port can be scheduled for heavy turnkey project shipments. We handle complete export documentation, including FORM E preferential tariff certificates under the ASEAN-China Free Trade Area, allowing Thai buyers to enjoy zero or reduced import customs duties.
We provide both on-site engineering dispatch and instant remote digital support. For on-site commissioning, our field service engineers travel to your Hat Yai facility to oversee mechanical anchoring, electrical wiring, program calibration, and hands-on operator maintenance training.
Additionally, every machine's PLC can be equipped with an industrial IoT gateway for secure remote diagnostics. If your electrical technicians ever require parameter troubleshooting or program updates, our Ningbo R&D engineering team can connect directly to your equipment via encrypted internet link within 2 hours.
Absolutely. We encourage all clients to courier their actual stator core stampings, enameled magnet wire spools, and slot insulation papers to our Ningbo factory prior to shipment. Our technicians complete comprehensive trial runs under production conditions.
We record high-definition multi-angle operational videos, provide high-voltage surge and hipot dielectric test reports of the inserted samples, and deliver precision dimension reports of coil head overhangs. Machines only ship once you review and formally approve the sample parts.
Whether you are automating a manual induction motor winding workshop, upgrading rubber processing machinery drives, or launching high-efficiency EV stator lines, Ningbo Nakro engineers are ready to configure your tooling.
