The Swiss industrial landscape represents the global gold standard for mechatronic precision, reliability, and engineering discipline. Whether building medical-grade micro-actuators in Neuchâtel, high-performance pump systems in Winterthur, or advanced electric traction drives along the Lake Geneva industrial belt, Swiss plant directors require manufacturing machinery that functions with uncompromising repeatability. Generic winding machines regularly fail to meet these demands due to excessive wire stress, thermal runout in high-speed flyer assemblies, and incomplete adherence to harmonized European safety directives.
As an established stator winding line manufacturer operating under rigorous ISO 9001 certified quality management systems, our automated production lines are built specifically to bridge the gap between high-volume efficiency and precision Swiss standards. Every automated workstation, from paper wedge insertion to final intermediate forming and lacing, is constructed on rigid cast-iron or heavy stress-relieved steel beds. This mitigates micro-vibrations that cause wire insulation fatigue and ensures that Swiss manufacturers achieve motor stator quality capable of passing demanding hipot, surge, and insulation resistance tests (exceeding 2,500V breakdown thresholds) under continuous operation.
Information Gain Architecture: Unlike conventional commodity machines, our automated lines integrate closed-loop servo feedback loops on every winding spindle, dynamic active wire decoilers, and real-time wire tension recorders. Every single wound stator can be stamped with a serialized data log including winding turn tension profiles, ambient resistance, and wedge placement verification, fully ready for integration into Swiss MES and ERP ecosystems via OPC UA.
Compliance in the Swiss Confederation is governed strictly by bilateral agreements harmonized with European Directives, specifically the EU Machinery Directive 2006/42/EC (transposed into Swiss federal legislation through the Product Safety Act, PrSG, and Ordinance on Machine Safety 930.111), the Electromagnetic Compatibility Directive (2014/30/EU), and Low Voltage Directive (2014/35/EU). Our machines provide comprehensive CE Declaration of Conformity dossiers, third-party verified mechanical and electrical risk assessments under SN EN ISO 12100:2010, and electrical safety architecture aligned with EN 60204-1 safety of machinery, featuring dual-channel emergency stop circuits with Pilz/Siemens safety relays meeting Performance Level d/e (PL d/e).

How our automated stator winding systems drive advanced micro-motion, alpine heavy duty, and e-mobility excellence.
Switzerland’s global lead in medical devices, dental surgical handpieces, and orthopedic power tools requires slotless and brushless stator winding at micro-diameters (down to Ø6 mm). Our high-precision multi-axis needle winders manipulate ultra-fine enameled copper wire (0.02 mm to 0.15 mm) without tension spikes, delivering high-temperature Class H/N insulation integrity resistant to thousands of autoclave steam cycles.
Operating in rugged mountainous environments from the Bernese Oberland to the Valais requires auxiliary blowers, hydraulic pump motors, and HVAC compressors that never fail. Our automated heavy-duty stator insertion machines process medium-to-large laminations (up to frame size 280) with automatic coil shaping and slot wedge placement, ensuring high dielectric strength under extreme sub-zero thermal cycling.
With the rapid adoption of premium e-cargo bikes, municipal electric utility transporters, and electric sports crafts throughout Switzerland, our automated hairpin and outer-rotor hub winding lines provide local factories with rapid changeover fixtures, precision coil terminal welding, and automated varnish trickling cells for IP67/IP69K motor enclosures.
Pioneering advancements shaping motor production lines across Western Europe.
To achieve carbon neutrality and conform to Swiss and European circular economy mandates, e-drive developers are pivoting rapidly toward rectangular copper wire architectures. Flat wire improves thermal conductivity from the slot center to the lamination stack by up to 25%, while maximizing the active copper slot fill up to 80%. Our automated hairpin lines execute automated 3D forming, paper insertion, crown twisting, and vision-guided laser welding in single linked sequences.
Swiss manufacturing engineers demand minimal on-site disruption during line commissioning. We construct fully simulated Digital Twin models of every customized winding and insertion cell before shipment. Through virtual Factory Acceptance Testing (FAT), kinematic speeds, interlock collision hazards, and cycle-time bottlenecks are audited and resolved in software, slashing on-site Site Acceptance Testing (SAT) at customer facilities to less than five working days.
For high-reliability robotics, aerospace sensors, and biomedical blood-pump motors produced in the cantons of Solothurn and Neuchâtel, airborne particulate contamination causes catastrophic micro-shortages. Our custom cleanroom stator winding machines are enclosed with HEPA-filtered laminar flow hoods, stainless steel paneling, and oil-free magnetic levitation pneumatic cylinders to maintain spotless processing environments.

Engineering Consultation Before Quoting: Our senior R&D engineering team conducts rigorous reviews of your stator lamination blueprints, wire enamel thickness ratings, winding schematics, and target monthly output. We design custom tooling, inserting blades, and flyer guiding shoes specifically tuned to your exact slot dimensions, preventing wire crossover defects and ensuring flawless series production.
Detailed technical, regulatory, and logistical guidance addressing common concerns of Swiss technical buyers.
In Switzerland, machinery imports fall under the Federal Act on Product Safety (PrSG, SR 930.11) and the Machine Ordinance (Maschinenverordnung, 930.111), which harmonize seamlessly with the European Machinery Directive 2006/42/EC. Every machine manufactured by Nakro destined for Switzerland undergoes a comprehensive EN ISO 12100 risk assessment.
We design our electrical control cabinets to conform fully with EN 60204-1, integrating CE-certified components (Schneider, Siemens, Omron, or Beckhoff). Physical safety fencing is reinforced by category 4 / Performance Level e (PL e) optical light curtains and safety gate interlocks. All accompanying technical documentation, electrical schematics, operating manuals, and maintenance guides are provided in accurate English, with German or French versions available upon engineering sign-off.
Yes. While our standard industrial equipment is equipped with reliable high-speed PLC platforms with multilingual HMI touchscreens, we frequently customize control architectures for European and Swiss OEMs.
We can configure your stator line with Siemens S7-1500 series PLCs, Sinamics servo systems, or Beckhoff TwinCAT PC-based control running EtherCAT bus topologies. Furthermore, we provide open OPC UA servers that publish real-time telemetry (cycle times, winding tension graphs, motor runout statistics, temperature alerts) directly to your plant-wide SCADA or MES infrastructure.
To ensure zero installation risk, our protocol consists of two structured phases:
1. FAT at our facility: We request that the client ship sample lamination stacks, copper wire reels, slot insulation paper, and commutators/shafts to our assembly facility. We perform continuous trial production runs to verify cycle time (seconds per stator), winding tension repeatability, hipot breakdown, and slot wedge tightness. Swiss clients are invited to inspect in person or conduct a multi-camera live video run-off with calibrated dimensional reports.
2. SAT at your Swiss factory: Our factory-trained field service engineers handle on-site uncrating, mechanical alignment, electrical hook-up, dry-cycle verification, and full-volume production run-off alongside your local operators, concluding with signed formal acceptance.
Lead time for standalone automatic winding or inserting machines typically ranges from 45 to 65 days. Complex turnkey lines with integrated robotics and automated conveyance require approximately 90 to 120 days from drawing freeze to FAT.
Shipments to Switzerland can be delivered under CIP Zürich/Basel (Air) or DAP/DDP terms via European port hubs (such as Rotterdam or Hamburg) with subsequent rail/truck transport into Switzerland. We provide full EUR.1 / Free Trade Agreement documentation to assist Swiss importers in optimizing customs duties. Critical wear-and-tear components (winding needles, wire guides, inserting blades) are provided with backup sets upon initial machine delivery, and emergency spares can be dispatched via DHL Express within 24 to 48 hours.
High slot fill (exceeding 70-75%) is essential for modern high-efficiency motors (IE4 and IE5 classes), but it carries risks of wire overlap, lamination scraping, and jammed inserting blades. Nakro solves this through three dedicated engineering strategies:
First, our insertion tooling is CNC-machined from ultra-dense tungsten carbide or vacuum-hardened SKD11 steel, polished to a mirror Ra 0.2 surface finish to minimize friction. Second, our multi-axis servo inserters utilize programmed speed profiles, slowing momentarily as the coil enters the narrow slot opening and accelerating once the wire clears the teeth. Third, our intermediate and final multi-jaw hydraulic or servo forming units press the end-windings accurately without damaging outer enamel layers, leaving adequate clearance for rotor insertion and electrical lead connections.
