Engineered by Zhejiang Rilvo Automation Equipment Co., Ltd. for extreme duty cycles, tight slot tolerances, and zero enamel scratching across induction, starter, and BLDC motor lines.
Understanding the micro-mechanics of simultaneous coil pushing, wedge feeding, and slot containment to eliminate interlaminar insulation damage and maximize copper slot fill factors.
Traditional pneumatic or mechanical cam coil embedding stations suffer from phase mismatch between the wire pushing blades and slot insulation wedge insertion magazines. Our 5 DQ-1 Model Stator Wire Embedding series utilizes closed-loop AC servo drives to synchronize the pushing rods and wedge pushers within ±0.01 mm of axial tolerance, preventing wedge buckle or wire shear.
Enamel coating micro-fractures lead to inter-turn short circuits and premature motor burnout under tropical Mekong Delta operating conditions. Rilvo guide blades and transfer tooling undergo specialized cryogenic treatment and mirror polishing (surface roughness Ra ≤ 0.05 μm) using high-grade imported tungsten-alloy tool steel to guarantee zero enamel degradation during high-speed insertion.
To comply with emerging industrial energy efficiency classes (IEC IE3 and IE4), stators demand maximum copper density inside core slots. By leveraging precision variable-pitch winding and uniform tooling expansion arrays, our equipment achieves tight slot compactness without wire crossover jams, reducing stator core end-turn bulking by up to 14%.
From agricultural water control equipment in Tra Noc Industrial Zone to high-duty shrimp pond aerators across the Mekong river basin, precision motor manufacturing is pivotal to South Vietnam's industrial output.
Intensive shrimp and catfish farming across Can Tho, Soc Trang, and Ca Mau depends on round-the-clock surface aerators. These continuous-duty 1.5 kW – 3.7 kW motors require absolute hermetic integrity and high starting torque. Our coil insertion stations ensure uniform coil symmetry, minimizing phase imbalance and preventing localized hotspots.
Seasonal delta flooding and low-lift rice paddy pumping demand submersible stators capable of sustaining prolonged thermal stress. Integrating our 5 DQ-1 Wire Embedding Machine with slot-cell wedge inserters provides resilient insulation barriers that survive moisture condensation and high operating currents without partial discharge.
Can Tho is the Mekong Delta's primary hub for aquatic processing (Pangasius and brackish shrimp). Processing facility compressor motors and conveyor blowers require high volumetric efficiency. Rilvo's precision flat-wire winding and coil insertion machinery maximize thermal dissipation inside washdown-duty motor enclosures.
With Vietnam's national roadmap accelerating two-wheeler electrification, OEM suppliers in southern industrial parks are transitioning to Brushless DC (BLDC) and Permanent Magnet Synchronous Motors (PMSM). Our specialized magnet inserters, fusing machinery, and rotor winders deliver the automation speed needed for scalable electric scooter hub motors.
How regulatory pressure under Vietnam's VNEEP-3 directive and rising labor expenses in Can Tho are redefining motor manufacturing equipment criteria.
The Vietnamese Ministry of Industry and Trade (MOIT) has accelerated enforcement of National Technical Regulations for Minimum Energy Performance Standards (MEPS). Motor manufacturers supplying commercial pumps, industrial ventilation, and textile equipment into Can Tho and Ho Chi Minh City face stringent phase-outs of inefficient IE1 motors.
Transitioning from standard IE2 to IE3/IE4 super-premium efficiency requires tighter slot geometric filling, shorter end-coil overhangs to reduce copper resistance (I²R thermal loss), and ultra-precise stator iron stacking alignment. Our CNC coil inserting and flat-wire shaping machines give factory engineers in Tra Noc Industrial Zone I & II the capability to manufacture high-efficiency motors with repeatable slot factor density.
Deploying Rilvo automated inserting lines delivers measurable operational savings over legacy manual inserting tables:
| Technical Parameter | Rilvo 5 DQ-1 Inserting Machine | Manual / Semi-Mechanical Jigs | Direct Benefit to Can Tho Plants |
|---|---|---|---|
| Cycle Time (Stator Core) | 16 – 32 sec/unit (Adjustable) | 10 – 20 min/unit | Over 20x output increase per workstation |
| Slot Fill Rate Capability | Up to 85% (High Copper Mass) | Max 65% - 70% before jamming | Direct compliance with MEPS IE3 & IE4 motor designs |
| Wire Scratch Defect Rate | < 0.05% (Cryogenic Guide Blades) | 3% – 7% (Manual tool damage) | Eliminates catastrophic field burnouts in humid delta ponds |
| Applicable Stator O.D. | Φ40 mm – Φ260 mm (Custom Tooling) | Limited by human grip strength | Handles micro-motor stators up to heavy pump frames |
| Stack Height Capacity | 20 mm – 250 mm | High variance in manual alignment | Consistent magnetic flux without core lamination warping |
Direct factory production, in-house component machining, and direct maritime supply routes to Vietnam ensure uncompromised machinery quality and immediate technical back-up.
Located in the Shatianyang Development Zone of Sanmen, Taizhou, Zhejiang, our campus features over 20,000 m² of operational CNC machining bays, casting facilities, and clean assembly halls, with a 30,000 m² expansion phase underway. We do not re-badge subcontractor frames; we machine guide rails, cams, and spindles in-house.
Accredited with national High and New Technology Enterprise credentials and China Compulsory Certification (3C), Rilvo holds 17 national invention and utility patents. Every stator coil inserting and rotor winding machine is subjected to our proprietary 72-hour full-load pre-shipment trial run using your provided stator laminations.
Sanmen is located within 2 hours of Ningbo Port, the world's premier shipping gateway. We provide flexible incoterms (FOB, CFR, CIF Cat Lai or Cai Cui Port, EXW) with rapid customs manifests, standard fumigated maritime crating, comprehensive circuit diagrams, and bilingual English-Vietnamese programming manuals.
Transparent engineering and logistical details for sourcing motor manufacturing equipment directly from our Zhejiang production base into Vietnam.
All machines exported to Vietnam are configured with heavy-duty 3-phase 380V ± 10%, 50Hz power supplies. We integrate Schneider and Mitsubishi electrical components with dedicated surge arrestors, line reactors, and thermal circuit isolation to absorb coastal grid dips common in peripheral industrial clusters.
Yes. Tooling kits (including pushing heads, guide blade baskets, and wedge pushers) feature precision dowel pins and quick-release mechanisms. Standard changeover between motor stack heights takes under 15 minutes, while an entire stator bore diameter alteration takes 30–45 minutes with basic hex tooling.
Maritime container freight from Ningbo to Ho Chi Minh City (Cat Lai) takes roughly 5 to 8 days port-to-port. Transit and road feeder clearance into Can Tho Industrial Zones (such as Tra Noc or Thot Not) typically takes an additional 2 to 4 days, ensuring fast equipment delivery.
Machine base frames receive multi-layer industrial polyurethane anti-corrosion enamel. All sliding surfaces, lead screws, and linear ways utilize high-grade chrome plating and automated centralized lubrication pumps that keep an active oil barrier over ground steel surfaces, resisting corrosion from coastal atmospheric humidity.
Absolutely. Our servo inserting force profiles can be programmed via the touchscreen HMI. For aluminum wire — which has lower tensile yield and higher ductility — the machine applies progressive speed ramps and gentle insertion curves to prevent wire elongation or necking.
Machines can be equipped with IoT remote diagnostic modules allowing our software engineers in Zhejiang to inspect PLC registers, diagnose sensor status, and update firmware online. We also provide full HD video commissioning tutorials and step-by-step guidance, along with on-site technician dispatch for turnkey multi-machine lines.
