Configured specifically to meet the high duty-cycle requirements, tight copper fill factors, and rugged thermal endurance demands of Manaus manufacturing plants.
Engineered with PLC industrial controllers and servo-driven blades to insert both copper/aluminum coils and slot insulating wedges concurrently into single-phase stators, preventing enamel damage.
High-speed dual-end simultaneous coil lacing system for industrial induction motors, subfractional pump motors, and compressor stators with programmable stitch tension and index cycling.
CE-certified micro-segment copper commutators offering superior thermal dissipation, dimensional stability, and low contact resistance for professional DC power tools and fractional DC drives.
High-precision reinforced hook-type commutators (NDPJ-HXQ-640A) designed to endure high centrifugal speeds and extreme thermal swings in power tool rotors and heavy-duty industrial grinders.
Ultra-low wear electrographitic and metal graphite carbon brush assemblies (NDPJ-TS-1) designed for automotive auxiliary actuators, starter assemblies, and Manaus motorcycle electronics.
High-remanence sintered NdFeB permanent magnets optimized for PMSM and BLDC motor stators and rotors, providing peak flux density for electric motorcycles and high-efficiency compressors.
Reinforced stamping rotor-stator hook commutator (NDPJ-HXQ-183) manufactured specifically for consumer electronics and white-goods appliances, ensuring extended brush lifespan under frequent starting torque.
Flat-face planar design commutator (NDPJ-HXQ-39) built for axial space-constrained electrical assemblies, fuel pumps, and miniature precision electric drives with CE-certified quality assurance.
Deploying automated stator manufacturing machinery in the heart of Amazonas demands comprehensive adaptation to regional supply structures, tax framework advantages, and extreme climatic realities.
Under the Processo Produtivo Básico (PPB) rules, OEMs must perform automated winding, inserting, and core lacing domestically in Manaus to qualify for statutory IPI, II, and ICMS tax reductions, moving past basic knock-down assembly.
Manaus exhibits year-round ambient relative humidity above 85% and temperatures exceeding 35°C. Our machines utilize tropicalized control cabinets with integrated Peltier coolers, sealed linear guides, and oxidation-resistant tooling blades.
With river-barge transport from Santos or direct feeder shipping up the Amazon River taking up to 35 days, our equipment is built with standardized off-the-shelf industrial PLC electronics, quick-wear swappable tooling, and comprehensive spare kits.
Brazil's mandatory energy efficiency mandates require strict adherence to minimum efficiency classes (IR3/IE3). Our tight-slot automatic coil insertion ensures minimal scrap rates, uniform winding resistance, and optimized slot fill factor ratios.
Driving operational excellence across key consumer, two-wheeler, and commercial manufacturing hubs located within the Amazonas corridor.
Manaus manufactures a critical percentage of Latin America’s split air-conditioners and industrial refrigeration units. Our high-stack stator lines manage stepped laminations and heavy enamel copper wire with automated intermediate and final forming to ensure hermetic motor integrity.
As Latin America’s premier motorcycle hub, Manaus OEMs are transitioning toward hybrid and pure-electric hub drives. We deliver dedicated outer-rotor wheel motor winding machinery and BLDC needle winding platforms with automated hook and terminal fusing.
From high-volume washing machine drive stators to subfractional blender and juicer motors, our single-phase and universal motor equipment ensures seamless winding, dynamic balancing, and comprehensive end-of-line electrical hipot/surge verification.
Navigating the rapid transformation from labor-intensive manual assembly cells to smart, Industry 4.0-enabled stator production ecosystems.
Driven by e-mobility advancements, manufacturers are transitioning from conventional stranded pull-in windings to rectangular hairpin stators. Hairpin designs yield copper fill factors greater than 70%, reducing thermal bottlenecks and raw material bulk.
Modern Tier-1 suppliers in the PIM industrial district require cloud-integrated line monitoring. Nakro equipment features native OPC UA connectivity, tracking per-slot wire tension, insertion press load, and hipot test values for 100% digital batch traceability.
Replacing manual destructive sample testing with integrated high-speed stations that execute surge test, micro-ohm resistance analysis, and partial discharge inspection directly within a 12-second takt time, ensuring zero defective coils enter final potting.
Founded in 2010 in Ningbo, Zhejiang, Ningbo Nakro Intelligent Equipment Co., Ltd. has evolved into a global leader in electric motor assembly automation. Operating from our modern manufacturing facilities spanning over 30,000 m², our engineering teams design, validate, and manufacture standalone semi-automatic units and fully integrated turnkey lines exported to more than 50 countries worldwide.
What differentiates Nakro is our holistic motor production philosophy. Rather than solely delivering machinery, we analyze your exact motor laminations, winding diagrams, wire diameters, and thermal class specifications. We supply matching critical sub-components—such as N52 neodymium block magnets, planar and hook commutators, electrical carbon brushes, and insulation systems—providing single-source responsibility from tooling setup to first-part qualification.
Every system destined for Brazilian manufacturers complies rigorously with NR-10 (Electrical Safety) and NR-12 (Machinery Safety) safety standards, equipped with Category 4 safety relays, keyed interlocks, and dual-channel emergency stop circuits.
