Nakro supplies versatile stator coil inserting systems alongside high-precision bearings, commutators, and carbon brush assemblies engineered to optimize industrial motor throughput.
Serving the logistical and light manufacturing core of Qormi, our automated coil inserting solutions address specialized marine, automotive rebuilding, and energy efficiency demands across the Maltese archipelago.
Qormi serves as an operational epicenter for commercial contracting, mechanical workshops, and HVAC infrastructure providers serving hotels and commercial complexes across Valletta, Sliema, and Marsa.
Proximity to the Grand Harbour and Marsamxett shipyards creates rigorous maintenance requirements for auxiliary alternator rewinding, deck hoist drives, and bilge pump stators.
With Malta’s national push toward transport decarbonization, urban delivery vans, electric scooters, and localized electric utility vehicles require dependable hub and drive motor rebuilding.
Industrial manufacturing across Southern Europe and Malta operates under stringent EU directives concerning industrial equipment energy consumption (IE3/IE4 Ecodesign Standards) and CE safety certifications (2006/42/EC). For electro-mechanical engineering facilities located in Qormi, upgrading from labor-intensive manual coil lacing to servo-driven automated coil insertion machinery represents a pivotal productivity leap. Ningbo Nakro Intelligent Equipment designs machine architectures that deliver high slot fill factors, eliminate wire surface scuffing, and ensure repeatable dielectric isolation integrity.
Ecodesign Compliance Mandate: Achieving IE3 and IE4 induction motor standards requires increasing the slot copper fill factor without damaging conductor enamel. Nakro’s multi-axis servo inserters achieve slot fill densities exceeding 80% while preserving enamel insulation breakdown resistance over 2,500V.
Traditional multi-stage rewinding involves winding insertion followed by a discrete mechanical pass for wedge indexing. Nakro’s industrial automatic insertion machines operate on a synchronized, dual-action horizontal or vertical kinematic configuration. Driven by industrial-grade Panasonic or Delta servo motors, the insertion blades and wedge pusher advance in precise micro-step ratios. The enamelled copper coils and pre-formed DMD, NMN, or Nomex insulation wedges enter the stator core slots simultaneously. This eliminates relative friction between the insulated slot liner and copper conductors, completely preventing turn-to-turn micro-abrasions and subsequent inter-phase dielectric short-circuits.
Operating machinery in an island environment such as Malta exposes manufacturing cells to ambient air characterized by high humidity and marine saline aerosols. Unprotected industrial equipment frequently experiences galvanic oxidation on sliding surfaces and guide tracks. Nakro machines designed for Mediterranean delivery feature hard-chrome plated tooling blades, nickel-treated push rods, and hermetically sealed electrical enclosures conforming to IP54/IP55 industrial protection standards. Pneumatics provided by SMC and AirTAC incorporate integrated coalescing air filtration systems to prevent moisture-induced valve lockups.
Unlike massive mega-factories in East Asia that run single stator geometries for months, workshops in Qormi routinely handle high-mix, medium-to-low volume production runs. Tooling turnaround speed is vital. Our stator coil inserting units feature rapid-change tooling fixtures allowing an experienced technician to transition between frame diameters (e.g., from IEC Frame 80 to Frame 112) in under 25 minutes. All parameters—including stator core stack height (ranging from 10mm to 350mm), slot count (8 to 72 slots), wedge length, and insertion stroke profiles—are digitally stored within the industrial touchscreen HMI, eliminating manual mechanical stops and prolonged downtime.
Backed by over 14 years of design and manufacturing excellence, Nakro pairs advanced mechanical fabrication with comprehensive supply-chain integration for global motor manufacturers.
All machinery adheres to strict quality management workflows. Machined parts, heat treatment, and precision grinding undergo coordinate measuring machine (CMM) inspection before mechanical assembly.
We execute factory trial runs using your exact stator laminations, slot insulation, and enamelled copper wire. Complete cycle videos, dimension logs, and surge/hipot test results are signed off prior to crating.
Beyond capital equipment, we supply matching structural components—including custom precision ball bearings, copper commutators, carbon brushes, and insulation paper—ensuring full-chain responsibility.
Experienced in international shipping across 50+ countries. Every machine is vacuum-sealed with anti-corrosive desiccants and encased in rugged seaworthy wooden crates for safe transit to Mediterranean ports.
Clear, direct answers regarding equipment voltage, electrical compatibility, customs clearance, and long-term after-sales support.
