From the Daedeok Innopolis R&D Special Zone to Yuseong-gu automation laboratories, our automated BLDC winding machinery powers next-generation mechatronics.
Collaborative robots, haptic surgical arms, and lower-limb exoskeletons developed in Daejeon require frameless BLDC torque motors with ultra-thin laminations and maximum copper slot fill factors. Our multi-axis needle winding rigs ensure slot fills exceeding 78% with zero wire crossover.
Partnering with Tier-1 defense contractors and aerospace research bodies in Central South Korea, our winding systems support precision BLDC reaction wheel motors, gimbal stabilizers, and missile fin positioning servos demanding zero cogging torque and aerospace-grade phase balance.
Daejeon’s logistics innovation hubs rely on in-wheel direct-drive hub motors. Our automated wheel motor winding machines wrap concentrated coils directly onto segmented or solid outer stators, accommodating heavy magnet wire without compromising enamel dielectric strength.
South Korea’s Ministry of Trade, Industry and Energy (MOTIE) has intensified national energy efficiency mandates, steering industrial motor developers toward IE4 Super Premium and IE5 Ultra Premium efficiency benchmarks. In Daejeon's mechatronics ecosystem, conventional induction motors are being systematically replaced by interior permanent magnet synchronous motors (IPMSM) and high-density BLDC drives.
Our intelligent winding machinery tackles the two primary barriers to achieving high efficiency: coil end-turn overhang losses and insulation degradation under high-frequency silicon-carbide (SiC) inverters. By utilizing multi-axis CNC needle trajectories and programmatic tension dampening, our equipment achieves tight slot packing with reduced copper weight, directly curbing harmonic losses and localized eddy current hotspots.
Combining 14+ years of specialized motor manufacturing machinery expertise with complete end-to-end component sourcing capability.
From stator lamination stacking, slot paper insertion, and high-speed CNC needle winding to commutator welding, dynamic rotor balancing, and final automated testing—we build cohesive lines that slash operational cycle times.
Unlike standard machine builders, Nakro supplies both high-precision production hardware and certified motor components: hook commutators, N52 NdFeB magnets, ferrite arcs, end shields, and shafts, ensuring perfect mechanical fitment right from trial runs.
Every piece of equipment is subjected to trial runs using the customer’s precise lamination stacks and enamelled copper wire. Detailed cycle-time documentation, high-speed video verification, and optical dimension checks are delivered prior to shipping.
