The Métropole de Lyon and the surrounding Auvergne-Rhône-Alpes region stand as France’s premier manufacturing corridor for advanced mobility, industrial pumps, precision robotics, and nuclear power components. As European industrial directives accelerate the transition toward higher efficiency classes (IE4 and IE5) and heavy decarbonization of transport, motor manufacturers operating in Vénissieux, Saint-Priest, Vaulx-en-Velin, and the broader Rhône Valley require assembly infrastructure that surpasses legacy semi-manual limitations.
Modern electric motor fabrication has evolved far beyond standalone winding stations. Whether manufacturing permanent magnet synchronous motors (PMSM) for regional electric bus drivetrains, brushless DC (BLDC) motors for medical prosthetics, or three-phase asynchronous stators for industrial machinery, the margin between commercial profitability and scrap generation is governed by three deterministic engineering variables: slot-fill ratio precision, copper-wire insulation integrity, and end-of-line metrological traceability.
Ningbo Nakro Intelligent Equipment Co., Ltd. (operating alongside NIDE technological suites) bridges this operational gap. Backed by an established manufacturing base encompassing over 30,000 square meters, ISO 9001 certified quality architecture, and more than 13 years of direct machine export into 50+ countries, we deliver fully integrated, turnkey electric motor assembly lines configured directly for the European regulatory and technical landscape.
Within the CARA (European Cluster for Mobility Solutions) network based in Lyon, original equipment manufacturers are systematically redesigning electric powertrains. The historical limitations of conventional random-wound round enamelled copper wire—principally low copper slot fill factors typically plateauing between 42% and 48%—result in severe thermal dissipation bottlenecks in modern, torque-dense drivetrains.
Our turnkey hairpin stator manufacturing lines engineered for Lyon-based Tier-1 and Tier-2 suppliers resolve this thermal and volumetric barrier. By executing automated flat-wire 2D/3D bending, precision paper insulation insertion, multi-head wire grouping, insertion, twisting, and closed-loop laser hair-pin welding with real-time pyrometric inspection, our systems reliably push copper slot-fill densities up to 72% to 75%. This represents a 35% reduction in copper losses, a dramatic reduction in machine volume, and elevated vehicle efficiency across city-bus stop-start cycles typical of the Grand Lyon metropolitan transit area.
Every motor line engineered for our European clientele is modularized to prevent mechanical bottlenecks, eliminate manual handling damage, and integrate predictive maintenance capabilities.
Automated uncoiling, progressive servo stamping, precision skewing, and fiber laser welding of silicon steel laminations to prevent interlaminar eddy-current losses.
High-speed feeding, creasing, cutting, and inserting of DMD, Nomex, or polyimide composite insulation paper into stator slots without edge tearing or creasing micro-cracks.
Configurable for flyer, needle, or transfer insertion winding. Synchronized servo motors maintain strictly monitored wire tension to prevent elongation and micro-stretching.
Progressive hydraulic and servo intermediate and final forming tooling to achieve stringent envelope dimensions, followed by automated dual-end lacing and commutator hook welding.
Automated resin application utilizing vacuum impregnation or precision continuous trickling. Completely cures voids, dramatically raises Class H thermal limits, and dampens mechanical vibration.
Comprehensive automated testing matrix. Every unit is subjected to non-destructive electrical and metrological validation prior to packaging, generating full batch traceability records.

The manufacturing base in Greater Lyon is uniquely specialized. Rather than commodity consumer goods, regional industrial facilities focus on high-reliability, safety-critical, and extreme-environment electromagnetic devices. Our assembly solutions are customized to address four core regional application domains:
Centering around Vénissieux and Saint-Priest, regional heavy vehicle systems require high-torque traction motors capable of enduring sustained thermal cycling. Our hairpin winding systems and automated rotor magnet insertion machines integrate robotic potting to safeguard permanent magnets against high-shock road vibration.
The chemical corridor south of Lyon (Saint-Fons to Feyzin) demands explosion-proof (ATEX) and hermetic induction motors. Our stator production lines specialize in deep slot insertion, high-dielectric mica tape inter-phase insulation, and automated vacuum resin impregnation to ensure total absence of micro-discharge arcs.
Spanning the Lyon-Grenoble medtech corridor, micro-motor developers manufacture ultra-high-speed BLDC motors for surgical drills and laboratory centrifuges. We build high-precision needle winding machines utilizing 0.08 mm wire that guarantee dynamic rotor balancing within ISO G0.4 standards at speeds reaching 60,000 RPM.
From packaging machinery manufacturers in Villeurbanne to textile automation in Roanne, regional equipment builders need flexible batch production. Our rapid-changeover stator winding cells utilize programmable recipe switching via HMI, allowing line retooling in under 20 minutes between disparate frame sizes.
Procuring automated machinery from an international exporter requires absolute alignment with European statutory directives. Equipment imported into the European Union without rigorous adherence to Harmonized European Norms risks immediate regulatory interdiction, customs holds at ports of entry such as Marseille-Fos or Le Havre, and serious workplace liability.
Every automated motor assembly line shipped by Ningbo Nakro to France is constructed in strict adherence to Machinery Directive 2006/42/EC, the Low Voltage Directive 2014/35/EU, and the Electromagnetic Compatibility (EMC) Directive 2014/30/EU. Safety circuits are designed up to Performance Level e (PL-e) and Category 4 under EN ISO 13849-1. Standard implementations include dual-channel safety light curtains (Type 4), interlocked mechanical safety gates with solenoid locking switches, keyed emergency stop clusters, and monitored pneumatic dump valves that eliminate stored mechanical energy during line stops.
Recognizing the operational maintenance protocols of French plants, our control systems avoid proprietary or obscure architectures. Lines destined for Lyon are built with Schneider Electric, Siemens S7-1500, or Rockwell Automation ControlLogix PLCs. All electrical cabinets utilize standard European terminal blocks (Phoenix Contact / Weidmüller), safety relays (Pilz / Sick), and FESTO or SMC pneumatic valves. Human Machine Interfaces (HMI) feature full bilingual English and French language toggling, comprehensive alarm diagnostics, and integrated troubleshooting schematics.
In accordance with the France 2030 industrial revitalization framework, digital connectivity is imperative. Our production lines integrate edge computing industrial PCs supporting OPC UA and MQTT protocols. Operational data—including winding tension curves, hook fusing current profiles, slot wedge insertion depths, and individual EOL testing parameters—are logged per serialized workpiece via laser-etched 2D DataMatrix codes. This data is seamlessly pushed to the client's enterprise Manufacturing Execution System (MES), allowing full traceability, predictive bearing wear analysis, and verified component-level carbon accounting.
