Nakhon Ratchasima (Korat), the strategic gateway to Isan and a key anchor of Thailand’s Board of Investment (BOI) Zone 3 industrial corridor, is undergoing an unprecedented transition toward high-efficiency industrial motors, electric mobility (e-bikes, e-trikes, light EV hub drives), and agricultural pump manufacturing. At Ningbo Nakro Intelligent Equipment Co., Ltd. (operating alongside our high-precision NIDE-engineered manufacturing lines), we supply Tier-1 global motor builders with fully integrated, CE-certified stator coil and wedge insertion solutions designed to eradicate manufacturing bottlenecks, wire scratching, and low slot-fill ratios.

For plant managers and production engineers in Nakhon Ratchasima’s industrial zones—such as Suranaree Industrial Estate and Nava Nakorn Korat—the operational efficiency of motor assembly lines hinges on the mechanical reliability of the coil inserting station. In conventional semi-manual operations, stator slot insulation is susceptible to mechanical tearing during wire push cycles, leading to catastrophic inter-turn short circuits and insulation resistance failures during end-of-line surge (hipot) testing.
Our China-engineered stator coil and wedge insertion equipment solves these structural challenges through a synchronized dual-servo drive architecture. Unlike hydraulic or pneumatic pusher mechanisms that suffer from stroke inconsistency and pressure drops, our dual-axis servo configuration separates the wire-pushing blade mechanism from the wedge guide stroke. As the insertion tooling introduces the pre-formed copper coils into the stator core slots, an ultra-precise cam-action wedge magazine feeds, cuts, forms, and inserts the Nomex® or DMD slot wedges at identical velocity, completely preventing enameled copper insulation scraping.
| Performance Parameter | Standard Market Inserters | Nakro / NIDE Stator Insertion Systems | Operational Impact for Korat Plants |
|---|---|---|---|
| Drive Mechanism | Hydraulic / Pneumatic Linkage | Dual-Axis Synchronous AC Servo Control | Eliminates oil leakage, minimizes ambient heat, ±0.01mm positioning |
| Max Stator Stack Height | 160 mm – 200 mm | Up to 350 mm (Customizable to 500 mm) | Accommodates heavy-duty submersible pumps & industrial compressors |
| Enamelled Wire Scratch Rate | > 0.45% per batch | < 0.02% (Near-Zero Tolerance) | Protects warranty margins; eliminates field insulation breakdown |
| Wedge Material Flexibility | Rigid Fiberboard Only | DMD, Nomex, Polyester Film, Mylar | Complies with Class F & Class H insulation export standards |

Furthermore, the thermodynamic realities of Northeastern Thailand—characterized by high ambient humidity and elevated workshop temperatures—demand robust mechanical components. Our machines utilize imported vacuum-quenched Cr12MoV tool steel and SKD11 components with hardness ratings exceeding HRC 60-62 for all insertion push fingers and wedge guides. This ensures sustained dimensional stability across millions of production cycles without mechanical deformation.
Engineered to integrate seamlessly with the unique industrial demands, supply chain configurations, and regional market pressures of Isan's primary industrial hub.
Supplying Tier-2 sub-assembly vendors producing electric motors for automotive chassis blowers, radiator cooling fans, and wiper systems. Supports stringent automotive quality tracing with automated barcode-linked torque and insertion resistance logging.
Isan is the agricultural center of Thailand. Our high-stack-length insertion machines process three-phase deep-well submersible pump stators with heavy gauge wire bundles, guaranteeing moisture-tight slot insulation for demanding agricultural duty.
Direct adaptation for local manufacturers assembling hub motors for electric motorcycles, scooters, and utility agricultural trikes. Compatible with high-density segmented stators and concentrated windings requiring high slot-fill ratios.
Strategic macro forces reshaping shop floors across Nakhon Ratchasima and why upgrading to intelligent stator production machinery is vital.
With Thailand’s Ministry of Energy and industrial standards aligning with international high-efficiency mandates, motor manufacturers must achieve higher slot-fill percentages. Our tooling delivers slot fills up to 78%, essential for IE3 and IE4 induction motors.
Despite Korat's deep workforce, skilled winding technicians are increasingly scarce as manufacturing expands. Implementing automated coil insertion machines reduces manual labor overhead by up to 75% while boosting daily line repeatability.
Corporations upgrading production machinery in Korat can capitalize on BOI duty exemptions and corporate income tax incentives. Nakro’s machinery features integrated OPC-UA and industrial Ethernet architecture, qualifying fully for smart factory grants.
