Founded in 2010 in Ningbo, Zhejiang Province, Ningbo Nakro Intelligent Equipment Co., Ltd. has established itself as an innovative high-tech engineering enterprise committed to advancing electric motor production technology worldwide. We specialize in the R&D, manufacturing, assembly, and turnkey commissioning of smart motor manufacturing equipment.
Our solutions encompass fully automatic coil winding machines, stator coil inserting lines, needle winders, armature hook welding systems, outer-rotor wheel hub motor assembly cells, and complete BLDC/PMSM manufacturing lines. Backed by an experienced team of electrical, mechanical, and automation engineers, we partner with electric motor manufacturers across over 50 countries to achieve higher winding accuracy, stable slot fill factors, minimal cycle times, and robust quality consistency.
A transparent look into our 30,000+ m² facility where high-precision motor tooling, assembly stations, and complete lines undergo rigorous Factory Acceptance Testing (FAT).
Where mechanical structures, high-torque servo drives, linear modules, and customized winding tooling come together under stringent engineering tolerances. Every stator fixture, needle nozzle, and inserting blade is machined and ground to micrometric precision to protect magnet wire insulation during ultra-high-speed operations.
Every single machine and turnkey line undergoes continuous dry runs and live material tests using the client's supplied laminations, wire gauges, and insulation wedges. Electrical safety (hipot, surge, DC resistance) and dimensional repeatability are fully recorded and confirmed on video prior to ocean-worthy export packing.
Designed to deliver long-term equipment reliability, minimal operator intervention, and rapid ROI for global motor plants.
Our in-house mechanical engineers create bespoke winding heads, coil pushers, and indexing tables mapped strictly to your rotor/stator slot geometry, lamination stack height, and conductor diameter.
Standardized on world-class industrial control architectures (PLC, intuitive touch HMI, precision closed-loop servos, and electronic tensioners) ensure repeatable turns count, clean slot filling, and recipe storage.
Adhering to strict ISO 9001 practices: incoming component grading, coordinate measuring machine (CMM) inspections on key parts, electrical cabinet safety stress tests, and recorded test-runs prior to release.
Over 13 years of machinery export experience. We support overseas customers with comprehensive video run-off signoffs, detailed English manuals, remote diagnostic access, and on-site engineering installation.
From single stand-alone precision work cells to turnkey automated assembly lines.
Integrated solutions for DC, universal, power tool, and starter motors. Covers shaft insertion, commutator press-fit, slot insulation inserting, flyer winding, commutator hot-stacking/fusing, and rotor dynamic balancing.
High-efficiency automated lines for 1-phase and 3-phase induction motors, deep-well pump motors, and compressor stators. Simultaneous coil and wedge insertion prevents wire enamel damage and ensures clean slot fill.
Dedicated multi-axis CNC needle winding systems for brushless motors utilized in consumer appliances, drones, power tools, and HVAC blowers. Delivers neat, non-crossing layer winding with programmable wire routing.
High-torque outer-rotor stator winding and final assembly lines engineered for e-bikes, electric scooters, e-rickshaws, and NEVs. Incorporates automatic magnet gluing, axle press-fit, and rotor-stator motor closing.
Specialized equipment for automobile alternator stators and starters, addressing demanding vibration-resistance and high thermal-grade insulation requirements for Tier 1 automotive motor subcontractors.
Complementary supply-chain support for global clients: precision commutators, deep-groove ball bearings, motor shafts, carbon brushes, slot insulating papers, end covers, and custom spare tooling.
Whether you require a single high-speed coil winding machine or a fully automated turnkey manufacturing line, Ningbo Nakro Intelligent Equipment Co., Ltd. will review your rotor/stator CAD drawings and deliver a customized technical proposal.
