Explore our factory-direct, CE-compliant stator winding, coil inserting, spot welding, and wedge paper inserting automation platforms designed for high-density slot architectures.
Modern electrical motor engineering demands an optimal balance between copper slot fill factor (ηcu), insulation film stress, and thermal dissipation. In high-efficiency industrial motors (IE3/IE4 standard) and traction drivetrains, stator wire winding is no longer a rudimentary mechanical winding procedure; it is a critical electromechanical calibration process. Automating stator wire winding eliminates manual lacing variability, micro-abrasions in the polyimide or polyamide-imide enamel layer, and uneven magnetic flux distributions.
When selecting automatic stator wire winding machinery in precision mechatronics ecosystems such as Domagnano, San Marino, engineering teams must evaluate three dominant technological typologies: Flyer Winding, Needle (Wander) Winding, and Transfer Needle Inserting systems. Flyer systems excel in external slot BLDC topologies and small armature cores with uninhibited flyer sweep paths. In contrast, dual-needle internal slot winding platforms navigate tight internal clearances, delivering dense conductor pack structures with wire turn position precision governed within ±0.05 mm.
Rilvo Automation integrates digital hysteresis magnetic tensioning and multi-axis closed-loop servo feedback across its stator winding line. This maintains constant gram-force tension throughout high-speed indexing (up to 3,000 RPM spindle velocity), mitigating dielectric breakdown hazards and corona discharge in high-voltage variable-frequency inverter operations.
Closed-loop servo active line feeding prevents tensile stress spikes on super-enameled round and rectangular wire, eliminating insulation thinning.
Modular stator guide fixtures and slot needles permit tooling changeovers in under 18 minutes, accommodating varying lamination stack heights.
Simultaneous coil insertion and slot wedge cuffing/sliding avoids manual handling, shielding ground wall insulation from shear fractures.
Equipped with dual optoelectronic safety light grids, enclosed polycarbonate hoods, and integrated emergency circuit diagnostic controllers.
Strategically situated in the high-precision manufacturing corridor of the Republic of San Marino, bordered by Italy's Emilia-Romagna motor valley, Domagnano hosts specialized production units requiring advanced automated coil winding machinery.
High-torque starter motors, compact alternators, and auxiliary cooling pump motors manufactured in the San Marino corridor demand heavy copper section windings with robust hot-stake commutator fusing capable of withstanding extreme vibration and thermal cycles.
Domagnano precision automation builders integrate multi-pole brushless DC motors into robotic articulation joints and CNC milling spindles. Our needle winding machinery deposits concentrated windings directly onto segmented or slotted stator laminations with near-zero air gap drift.
Industrial hermetic fluid handling equipment, residential circulation pumps, and heat exchange compressors utilize three-phase induction stators. Automatic coil embedding machines insert main and auxiliary coils simultaneously with phase barrier papers, guaranteeing insulation barrier integrity.

Under the European Union Ecodesign Directive (EU 2019/1781) and international standards adopted by San Marino, medium and large low-voltage AC induction motors face stringent minimum energy performance requirements (IE3 Premium and IE4 Super Premium Efficiency classes). Motors operating below these energy benchmarks cannot be integrated into exported machinery or industrial plants.
Meeting IE4 and emerging IE5 efficiency standards directly relies on increasing the copper volume in the stator core slots without altering external frame dimensions. Rilvo Automation's automatic winding and inserting machines maximize the electromagnetic conductor density, minimizing end-turn copper overhang lengths. Shorter end turns substantially lower stator phase resistance, cutting thermal losses while economizing on expensive magnet wire.
Furthermore, Domagnano manufacturers transitioning toward light electric vehicles (e-bikes, urban cargo movers, and agricultural robots) increasingly mandate wave-shape coils and flat wire shaping equipment capable of handling CCA (copper-clad aluminum) or square section enamel wire with zero edge de-lamination.

Yes. Our in-house R&D engineering division (comprising 36 specialists) configures custom insertion tooling, needle arrays, wedge formers, and clamping mandrels directly from your 2D/3D part drawings (.STEP, .DWG). We customize tooth width clearances, skew angles, stack heights, and slot opening tolerances to eliminate scratch defects on sensitive insulation paper.
Machinery shipments originate from our factory via the international deepwater port of Ningbo or Shanghai, routing to Italian entry ports (such as Genoa, Ravenna, or Ancona) before onward overland transit to Domagnano, San Marino. We deliver under FOB, CFR, CIF, or DDU/DAP terms, issuing comprehensive Commercial Invoices, Packing Lists, Certificates of Origin, and Phytosanitary Crating Documentation for frictionless customs clearance.
We do not dispatch equipment based solely on dry simulation runs. Clients supply samples of their actual stator core laminations, slot insulation paper, and enameled magnet wire. Our quality team runs continuous 50-unit winding and insertion tests, recording cycle times, dielectric breakdown resistance, slot fill consistency, and dimensional tolerances, verified via HD video FAT audit.
High-wear consumables—including winding nozzles, tungsten carbide guides, push rods, and wire cutoff blades—are manufactured to standardized tolerances. A comprehensive 2-year maintenance spare parts kit accompanies each machine. Replacement tooling or expedited components are shipped via DHL/FedEx courier with typical delivery windows of 3 to 5 business days to San Marino.
Yes. For applications sensitive to material costs or component weight (such as e-bike hub drives or low-voltage auxiliary armatures), models such as our SDZ-130GS feature specialized micro-inverter fusing algorithms designed for CCA conductors. Precise energy pulsing prevents vaporization of the thin outer copper layer while delivering homogeneous core bond strength.
