Engineered for high slot fill factors, minimal wire tension deviation, and rapid changeovers. Fully adapted to European 400V/50Hz industrial grids and CE machinery directives for assembly plants across Bucharest, Ploiești, and Pitești.
For electric motor manufacturers operating in the industrial corridors around Bucharest, dynamic balance and winding symmetry determine whether an armature achieves its target lifetime. Universal motors, starter motor armatures, and brushless permanent magnet rotors operate under severe thermal cycling and centrifugal mechanical forces often exceeding 18,000 RPM in modern power tools and automotive sub-assemblies.
Our automated rotor winding systems integrate closed-loop multi-axis CNC servo tensioning. Unlike conventional friction tension brakes that exhibit stick-slip behavior at sudden flyer acceleration, our digital electronic actuators actively modulate magnet wire deceleration during the hook connection cycle. This eliminates micro-scratches on wire enamel, prevents wire thinning, and secures consistent coil resistance balance between adjacent commutator segments.
Romania has positioned itself as Eastern Europe's engineering workshop, driven by extensive automotive tier-1 supply networks, HVAC assembly, and smart electric appliance production. Rilvo delivers customized production units engineered to integrate directly into domestic manufacturing ecosystems.
Direct supply to factories fabricating engine cooling fans, starter motor armatures, window lifter drives, and electric power steering (EPS) motors. Our automated machines fulfill stringent VDA 6.3 and IATF 16949 audit requirements, providing complete lot traceability for winding tension and commutator hot-staking weld depth.
Integration of heavy-duty stator embedding and coil wrapping systems (5 DQ-1 and XB-1GZ series) for centrifugal water pumps, agricultural irrigation systems, and commercial ventilation units. Designed to process thermal class H and F enamels with high slot-fill ratios for premium energy efficiency (IE3 and IE4 ratings).
High-speed commutator winding machines tailored for 12V–36V DC armatures and brushless outer-rotor hub winding. These automated cells deliver compact packaging, high mechanical tolerance control, and clean hook welds without spatter, catering to the growing domestic demand for e-mobility and robotic actuators.
The manufacturing corridor connecting Bucharest, Ilfov, and neighboring industrial hubs is undergoing a structural transition fueled by EU decarbonization directives and nearshoring trends. As automotive OEM lines adapt from traditional internal combustion components to mild-hybrid (MHEV), battery electric (BEV), and high-efficiency auxiliary drives, rotor and stator winding lines must accommodate increasingly complex geometries:
Flat copper magnet wire winding is rapidly supplanting round wire in automotive auxiliary motors. The rectangular cross-section achieves slot fill factors greater than 70%, reducing copper losses and motor weight while facilitating superior heat dissipation in compact engine bays.
European OEMs are shifting sub-tier component manufacturing back to Romania to compress supply chains and protect against intercontinental disruptions. This demands highly automated winding equipment with fast changeover tooling (under 20 minutes) to manage diversified product batches.
With industrial motors mandated to comply with strict IE3/IE4 minimum efficiency standards, winding equipment must ensure uniform coil loop tension and intact enamel insulation, eliminating inter-turn micro-discharges and partial discharge risks under high-frequency VFD inverters.
Headquartered in Zhejiang's high-tech manufacturing zone since 1998, Zhejiang Rilvo Automation Equipment Co., Ltd. combines nearly three decades of precision machine-tool building with end-to-end export support for Romanian and European facilities.
With 20,000 m² of completed workshop space and over 150 dedicated machine-tooling units, all structural castings, ground spindle guides, flyer heads, and wire-shaping dies are fabricated internally. We do not depend on external job-shops, ensuring complete control over metallurgical tolerances and metallurgical hardening.
Our automation cells adhere strictly to ISO9001 quality management procedures and hold 17 national invention and utility patents. Equipment designated for European delivery is built with genuine CE safety guards, interlocked safety doors, dual-channel E-stop circuits, and optical light curtains.
Exporting across Eastern Europe, Asia, and the Americas, our dedicated trade engineers coordinate turnkey logistics under FOB Ningbo, CFR, CIF Constanța/Bucharest, and EXW terms. We provide English-language HMI interfaces, dual-language electrical schematics, and complete spare parts packages.
