Technical Whitepaper: Stator Production Engineering for Šiauliai's Manufacturing Transition
Šiauliai represents Lithuania's key industrial crossroad, linking the Baltic logistic arteries with a strong heritage in mechanical engineering, precision electronics, and industrial component manufacturing. As European eco-design regulations mandate IE4 and IE5 super-premium efficiency standards across industrial drives and commercial pump systems, local engineering teams face a crucial transition: moving from labor-intensive, semi-manual winding setups to deterministic, closed-loop automated stator assembly lines.
Our stator manufacturing architecture delivers the nanosecond-level servo control required to maximize the copper fill factor (slot space factor) up to 78% in hairpin designs and over 48% in conventional random wire-wound configurations. Nakro machinery eliminates mechanical stress on magnet wire enamels during insertion, guaranteeing zero partial discharge and absolute dielectric integrity under inverter-fed PWM voltage spikes.

Frequently Asked Questions for Šiauliai Buyers
Detailed answers regarding delivery logistics, CE machinery conformity, factory run-off trials, and on-site integration in Lithuania.
Q: What is the logistics route and transit time for machinery shipping to Šiauliai?
Shipments depart from Ningbo or Shanghai port via containerized ocean freight directly to the Port of Klaipėda, Lithuania (typically 32 to 38 days maritime transit). From Klaipėda, containerized machinery or break-bulk freight is moved directly by road transport via the A1/A11 corridors to your facility in Šiauliai within 24 to 48 hours following customs clearance.
Q: Do Nakro stator production machines comply fully with EU CE Directives?
Yes. All machines exported to European Union member states are engineered and certified in strict compliance with the European Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and Electromagnetic Compatibility (EMC) Directive 2014/30/EU. Equipment is fitted with dual-circuit safety interlocks, optical light curtains, and Schneider/Siemens electrical protection components.
Q: How is Factory Acceptance Testing (FAT) handled before dispatch?
Before shipment, we conduct comprehensive dry-cycling and live winding trials using your actual stator lamination stacks, slot paper, and magnet wire shipped to our Ningbo testing facility. We provide high-definition run-off video recordings, coordinate dimensional CMM reports, and welcome Lithuanian client engineering teams or third-party inspectors (such as SGS or TÜV) to sign off on-site.
Q: What support is provided for on-site commissioning and training in Lithuania?
We provide two commissioning pathways: our senior field service engineers can deploy on-site to your Šiauliai manufacturing plant to oversee mechanical anchoring, electrical leveling, trial runs, and operator safety training; alternatively, we support rapid remote commissioning using pre-labeled terminal harnesses, English HMI systems, and remote PLC diagnostics via secure VPN gateways.
Q: Can the stator equipment handle multi-model changeovers with different stack heights?
Yes. Our machines are designed with modular quick-change tooling. Adjusting for different stack heights within the same lamination OD profile is configured entirely via the digital HMI touchscreen through high-resolution servo ball screws, requiring zero mechanical tear-down and enabling complete changeovers within 10 to 15 minutes.
Q: How do you provide long-term spare parts and consumables?
Critical wear components—such as tungsten carbide winding needles, coil insertion push blades, paper forming guides, and wire tension ceramic eyelets—are stocked for priority express courier dispatch (3-5 days delivery to Lithuania). Standard electrical and pneumatic components (SMC, Festo, Siemens, Schneider) are readily available through local Baltic distributors.
