Procuring assembly machinery from an overseas OEM demands adherence to strict European compliance frameworks. Our machines are designed according to Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, and Low Voltage Directive 2014/35/EU.
Industrial electric motor assembly entails violent rotational kinetics, pneumatic press-fitting of tightly matched bearings, high-temperature varnish curing, and elevated electrical insulation testing. CE certification is not an arbitrary label; it requires rigorous risk reduction architecture under EN ISO 12100:2010 safety-of-machinery standards.

Procurement directors are shifting away from standalone machinery toward integrated, cyber-physical automation platforms. Stay ahead of changing supply-chain imperatives.
Automotive traction and industrial high-torque applications are transitioning rapidly to rectangular wire hairpin stator designs, demanding assembly lines capable of 2D/3D CNC bending, precision slot twisting, and continuous laser welding.
Tier-1 manufacturers are moving away from multi-vendor fragmentation. Procurement contracts now focus on unified turnkey builders who guarantee Overall Equipment Effectiveness (>88% OEE), mean time between failures (MTBF), and single-source liability.
MES (Manufacturing Execution Systems) integration via OPC-UA/MQTT protocols has become an essential RFP requirement. Every press-force curve, torque value, and dielectric test must be serialized to individual 2D QR codes on the motor housing.
A frequent error among plant expansion buyers is authorizing shipment before achieving verifiable, repeatable trial parameters. Nakro mandates that every automated motor line undergo full validation before packing:
Share your 2D/3D motor drawings and targeted daily output. Our sales engineers deliver custom line layout simulations and CE-compliant equipment proposals within 48 business hours.
From multi-axis CNC needle winders to AI-driven optical verification, discover the emerging technologies deployed inside Nakro's high-efficiency machinery.
Traditional mechanical friction clutches cause copper wire stretching and enamel micro-fissuring. Next-gen winders utilize magnetic powder brakes paired with closed-loop servo tension controllers, maintaining ±0.5g tolerance across acceleration phases.
High-resolution industrial telecentric cameras combined with 6-axis articulated arms eliminate mechanical hard-tool changeover. Magnets, bearings, and rotor shafts are identified, oriented, and seated with positional accuracy down to ±0.015mm.
Inverter-controlled intermediate-frequency DC resistance welding delivers microsecond-level feedback on heat energy. This produces consistent bonding between copper wire and commutator tangs without thermal annealing of surrounding insulation.
For brushless DC (BLDC) and PMSM designs used in e-mobility, increasing the slot copper fill factor from 45% to over 70% is essential for heat reduction and range extension. This efficiency is achieved through segmented stator cores. Nakro designs dedicated multi-station automated lines where individual T-segments are wound simultaneously on high-speed needle machines, interlocked with micro-micron clearance, and welded into continuous rings via fiber laser welding.
Based in Ningbo, China, Ningbo Nakro Intelligent Equipment Co., Ltd. combines dedicated R&D engineering with end-to-end component manufacturing to de-risk high-volume motor production.
From uncoiling silicon steel sheets to end-of-line vibration and back-EMF analysis, we configure complete, cohesive production environments without relying on third-party design houses.
