Precision-engineered automated coil insertion, CNC turning, and high-tension wire winding machines matching ISO9001 European automotive tier specifications and regional manufacturing standards.
Strasbourg and the wider Grand Est region constitute one of Western Europe's most resilient industrial manufacturing arteries. Positioned right on the Franco-German border along the upper Rhine valley, manufacturing facilities across Alsace—extending from Mulhouse through Strasbourg to Haguenau—operate under strict European technical directives (CE marking, EN 60034, ISO 9001, and IATF 16949). The current transition across European automotive, HVAC, railway traction, and industrial processing requires a comprehensive leap in stator manufacturing capabilities: moving away from conventional distributed round-wire windings to high-fill precision winding, concentrated hairpin technologies, and automated multi-axis inserting systems.
As a seasoned stator winding machine supplier for Strasbourg's tier suppliers and motor engineering plants, our systems are built specifically to solve the core mechanical vulnerabilities inherent to modern high-density motor lamination stacks. High-slot-fill motor designs dictate that insulated magnet wires undergo significant physical strain during insertion. If tension profiles, insertion foot paths, and push tooling are poorly coordinated, micro-fractures in the polyamide-imide (PAI) or polyester-imide (PEI) wire enamel will manifest. Our machines, such as the DQ-2 Stator Coil Inserting Machine and the Automatic Servo System Stator Coil & Wedge Inserting Machine, incorporate multi-axis closed-loop servo synchronisation, ensuring zero enamel abrasion even when managing delicate rectangular copper profiles.
Automated flat wire (hairpin) shaping and automated insertion allow coil density to rise significantly compared to manual or pneumatic winders, directly raising electric machine torque density and thermal dissipation across Alsace manufacturing lines.
Using ultra-hardened tool steels (Cr12MoV, tungsten-carbide polished inserts) with micro-ground push-rod clearances, wire insulation remains unharmed throughout aggressive slot-filling passes, guaranteeing long partial-discharge inception voltage (PDIV) lifetimes.
Real-time mechanical torque monitoring, displacement profiling, and automated optical detection on every cycle ensure out-of-tolerance stators are flagged prior to downstream varnish impregnation and final encapsulation stages.
The manufacturing landscape around Strasbourg features a dense network of industrial sub-suppliers serving major German, French, and Swiss original equipment manufacturers (OEMs). Industrial motor builders in the Bas-Rhin department do not operate on standardized one-size-fits-all lines; they handle high-mix batches ranging from specialized e-mobility sub-assemblies to heavy duty servomotors and water circulation pump drives.
Production of high-efficiency 48V mild hybrid starter-generators, brushless DC auxiliary steering motors, and EV compressor stators that mandate tightly controlled slot-end turn geometry and automated wedge insulation paper placement (via DFC-1 systems).
Alsace’s proximity to cross-border high-speed rail corridors drives procurement for traction motor rebuild lines. Machines like the ZXB-1 Flat Wire Winder construct high-amperage stator and rotor packages capable of resisting thermal degradation under severe cyclings.
The biomedical robotics sector in the Strasbourg Eurometropolis requires ultra-fine multi-pole brushless motor windings. Multi-servo dynamic micro-winders produce stator coils with micro-gauge wires under tightly regulated constant-gram tensioning.
The table below provides direct engineering specifications across our automated stator coil insertion, wedge insulation, and armature finishing lines, helping local technical directors evaluate throughput and cycle compatibility.

As the French government and the European Union enforce strict sustainability and energy-efficiency directives under the Ecodesign Directive (EU) 2019/1781 for electric motors (demanding IE4 and IE5 Super Premium Efficiency classes), regional manufacturing executives are compelled to overhaul aging semi-automated workshop equipment.
1. Shift to Hairpin & High-Slot-Fill Rectangular Wire: Strasbourg automotive subcontractors are rapidly migrating away from haphazard random-wound round wire toward structured flat-wire configurations. Flat wire significantly decreases copper void space, eliminates thermal hotspots, and boosts continuous current capacity. This requires specialized shaping and inserting machinery with micrometer-level mechanical indexing to prevent corner-radius pinholes.
2. Rapid Tooling Changeover for Agile Production: Small-batch, high-mix runs dominate specialized electrical machinery workshops in Haguenau, Schiltigheim, and Strasbourg. Modern stator suppliers must deliver modular tooling sets allowing conversion between 24-slot, 36-slot, 48-slot, and 72-slot lamination cores in under 30 minutes, supported by recipe recall stored directly in the HMI panel.
3. Carbon Footprint Minimization & Circular Remanufacturing: The circular economy is particularly robust in eastern France, where commercial vehicle alternators and starter motors undergo extensive remanufacturing. Re-winding machines, such as our Automatic Starter Coil Wrapping and SZC-3 CNC Lathing units, allow remanufacturers to match or exceed original OEM tolerances while minimizing raw copper waste.

Our 36-member dedicated R&D engineering division is guided by an industry pioneer honored with the National Knowledge-Worker Model award, holding 17 national invention and utility patents spanning winding, wedge insertion, and welding dynamics.
Below are clear, highly detailed answers addressing the questions French procurement managers, plant directors, and electrical engineers regularly present when sourcing automated equipment from our factory.
Yes. All machines exported to France and the European Union are constructed with industrial electrical components rated for standard 400V 3-phase, 50Hz electrical supply networks. Control circuits run on stabilized 24V DC, and our control cabinets employ CE-certified switchgear, circuit breakers, and emergency stop circuits compatible with European machinery safety norms.
We support standard Incoterms including FOB (Ningbo or Shanghai), CIF (Port of Le Havre, Antwerp, or Rotterdam), and DAP/DDP delivery directly to your facility in the Strasbourg Eurometropolis. From major European container terminals, cargo travels smoothly via inland waterway barge or direct truck freight into Alsace.
Customization is fundamental to our OEM/ODM operations. Buyers send their 2D/3D lamination CAD profiles (stator outer diameter, inner bore, slot shape, tooth shoe clearance, stack height) along with copper wire gauge and turn counts. Our engineering division fabricates custom tooling blades, guides, and push-feet matching your exact envelope.
We require raw motor lamination stacks and authentic enameled copper wire from the customer prior to factory sign-off. We perform multi-hour continuous dry and wet test runs, measure cycle time, run insulation breakdown tests, and deliver high-resolution continuous video footage for formal Factory Acceptance Testing (FAT) approval.
Each shipment includes an exhaustive mechanical and electrical schematic manual, complete PLC/HMI ladder logic documentation, and a high-wear replacement kit (including insertion blades, push fingers, wire guide needles, and air pneumatic seals). We provide remote video-assisted setup, remote diagnostic network connectivity, and on-site deployment assistance.
Machines like our DFC-1 and Automatic Servo Wedge Inserter utilize a synchronized feeding, creasing, cutting, and inserting mechanism. The insulation paper (Nomex, DMD, or composite film) is pre-formed with uniform edge cuffs and guided by precision carbide-coated tracks straight into the slot cell prior to wire entry, preventing cell ruptures or pinholes.
Send our senior engineering team your stator lamination drawings, coil specifications, and target cycle rates. We will compile a tailored manufacturing layout, custom tooling feasibility assessment, and formal project quotation within 24 hours.
