High-precision winding, inserting, forming, and spot welding machines calibrated for copper slot-fill optimization, low cycle times, and Industry 4.0 production environments.
The Autonomous Community of Aragon, centered around the metropolitan industrial corridors of Zaragoza, stands as an indispensable juggernaut in the European automotive landscape. Generating over 30% of the regional GDP through mobility and manufacturing, the region is underpinned by the massive Stellantis production complex in Figueruelas and a sophisticated matrix of more than 300 Tier-1, Tier-2, and Tier-3 component suppliers associated with the Clúster de Automoción y Movilidad de Aragón (CAAR). With the aggressive transition from internal combustion engines (ICE) toward battery electric vehicles (BEVs) and 48V mild hybrids, the demand for localized, high-speed, flexible EV motor production line factories in the Zaragoza market has surged dramatically.
Backed by Spanish national PERTE VEC (Strategic Project for the Recovery and Economic Transformation of the Electric and Connected Vehicle) initiatives and EU NextGeneration funding, Zaragoza has solidified its standing as a multimodal logistical and engineering nexus. The Plataforma Logística de Zaragoza (PLAZA)—one of Europe’s largest logistics hubs—provides instantaneous access to Madrid, Barcelona, Valencia, and the French border via high-capacity rail and motorway corridors. However, local automotive suppliers face severe competitive pressures: they must modernize aging winding and assembly equipment to meet stringent OEM cycle times (often below 45 seconds per finished stator), improve slot-fill ratios for improved thermal efficiency, and guarantee zero-defect production through complete telemetry integration.
Direct integration with production architectures for small and compact e-CMP/STLA platforms. Machine lines must guarantee rapid changeovers, strict traceable torque/crimping metrics, and high uptime.
Unmatched intermodal access enables JIT (Just-In-Time) and JIS (Just-In-Sequence) stator, rotor, and sub-assembly delivery to assembly halls across the Iberian Peninsula and southern France.
Capital machinery acquisitions qualify under circular economy and energy-efficiency grants when integrated with intelligent energy recovery, low pneumatic loss, and full SCADA logging.
Building an electric drive manufacturing line requires a cohesive, uninterrupted sequence from bare lamination stacking to end-of-line electrical testing. In legacy manufacturing setups, disparate machines create bottlenecks, increase scrap rates through manual handling, and present communication incompatibilities. Zhejiang Rilvo Automation Equipment Co., Ltd. solves these inefficiencies by engineering integrated, cell-based, and continuous automated production lines that link stator insulation, coil winding, wire insertion, forming, welding, impregnation, and dynamic balancing under a unified PLC control architecture.

In high-performance traction motors and auxiliary brushless DC (BLDC) drives, the choice between traditional round-wire distributed windings and rectangular-wire (hairpin) configurations determines the thermal ceiling and torque density of the drive unit. For high-volume automotive suppliers in Zaragoza targeting Tier-1 supply chains, Rilvo equips flat wire lines with precision CNC stripping, CNC bar forming, and automated crown-twisting modules that prevent enamel stress fractures. By preventing microscopic insulation micro-cracks during the bending and twisting phase, partial discharge resistance is preserved across the entire 800V operating envelope of modern EV platforms.
Factory automation investments in the Zaragoza region address a diverse range of electrification programs. Rather than focusing exclusively on large passenger car main traction units, the industrial landscape demands versatile lines capable of producing auxiliary, micro-mobility, and industrial e-drive configurations:
Automated lines for high-efficiency electric power steering (EPS), active suspension actuators, electronic braking systems (EBS), and thermal management coolant pumps manufactured in Zaragoza's Tier-1 industrial parks.
Belt-driven Starter Generators (BSG) requiring heavy round or flat wire wave windings. Our 4-BL-1 and ZB-302 series deliver robust coils capable of handling rapid recuperation current cycles without degradation.
With Zaragoza’s leadership in urban mobility testbeds (Mobility City), regional contract assemblers leverage Rilvo outer-rotor and hub motor winding tooling for electric cargo tricycles, mopeds, and lightweight delivery vans.
As Aragon accelerates toward its goal of becoming an electrified, carbon-neutral manufacturing leader, the technical specifications for capital equipment have evolved dramatically. Production engineering directors are seeking specific operational capabilities:
1. Shift to Hairpin and Continuous Continuous Pin Winding: While traditional distributed winding retains a strong foothold in auxiliary motors, main traction lines demand flat-wire hairpin winding. Rectangular conductors drastically reduce copper overhang at the coil heads, cutting electrical resistance losses by up to 25% while optimizing thermal dissipation directly through the stator housing jacket.
2. Full Digital Traceability and MES Integration: In accordance with European OEM audit protocols (VDA 6.3, IATF 16949), every single motor coming off a line in Zaragoza must carry an immutable serial ID linking it to its winding tension profile, welding current/voltage graph, varnish cure curve, and electrical insulation test metrics. Rilvo automation systems integrate native OPC UA and Profinet interfaces to stream real-time operational data directly to factory MES systems.
3. Energy Recovery and Low-Emissions Operation: With European energy pricing remaining volatile, our equipment integrates kinetic energy recovery systems (KERS) on high-inertia spindle drives and energy-storing pulse magnetizers (DZ4-2000), drastically lowering peak kilowatt-hour draw during mass production shifts.
