1. Kinematic Precision: The Mechanics of CE Certified Double-Side Lacing
In modern industrial motor production, the structural integrity of the stator winding overhang dictates the mechanical, dielectric, and operational longevity of the motor. A CE Certified automatic double side stator coil lacing machine provides exact geometric alignment and high-tensile stabilization on both front and rear coil heads concurrently. Unlike legacy manual binding or unbalanced single-side lacing, the dual-needle synchronous drive operates with closed-loop servo tension regulation, preventing asymmetrical mechanical stress across sensitive inter-turn insulation.
Operating with industrial programmable logic controllers (PLCs) paired with responsive touch human-machine interfaces (HMI), our double-side coil lacing systems support slot-by-slot lacing, interval-slot lacing, and multi-pattern perimeter binding. This high mechanical flexibility guarantees that phase-barrier insulations are tightly immobilized against harmonic oscillation, thermal expansion, and mechanical vibration, satisfying the rigorous low-voltage and electromagnetic compatibility directives mandated by CE compliance standards (EN 60204-1 safety of machinery electrical equipment).
“Simultaneous dual-head lacing cuts operational cycle times by up to 55% compared to two-pass single-side setups, while maintaining an unyielding tension threshold (±1.2 N) that eliminates harmonic resonance within electric motor stator coil packages.”

3. Industrial Localization: Powering Bien Hoa's Advanced Manufacturing Belt
Located in the heart of Dong Nai Province, Bien Hoa City represents Vietnam's foundational manufacturing engine. With dense clusters of heavy and light industries concentrated in Bien Hoa 1, Bien Hoa 2, Amata, and Long Binh Industrial Parks (LOTECO), the demand for high-efficiency electric motors has skyrocketed. Local factories are transitioning from labor-intensive manual assembly to fully automated and semi-automated production cells to comply with international energy performance ratings (IE3 and IE4 efficiency standards).
In this demanding regional ecosystem, motor production engineers in Bien Hoa require machinery designed for durability, climatic resilience, and localized maintainability. The sub-tropical humid environment demands corrosion-resistant treated guide assemblies, tropicalized electrical cabinets, and standard industrial component brands (such as Mitsubishi, Siemens, Delta, Airtac, and SMC) that are readily serviceable in Southern Vietnam without long overseas procurement lead times.
Local Production Scenarios
Specialized Applications Across Bien Hoa & Dong Nai
Precision-engineered tooling tailored specifically to the domestic manufacturing demands and export-oriented plants throughout Southern Vietnam's leading industrial corridors.
High-Volume Fan & HVAC Motors
Engineered for table, ceiling, and industrial ventilation fan makers in Bien Hoa Industrial Zone 2. Accommodates 8-slot, 16-slot, and 24-slot single-phase stators, providing tight wire bundling with synthetic polyester binding twine to handle continuous aerodynamic counter-pressures.
Agricultural & Submersible Water Pumps
Supplying the extensive agricultural heartlands surrounding Dong Nai and the Mekong Delta, water pump motors must withstand rigorous thermal cycling and moisture. Double-side lacing ensures that heavy-gauge copper coils remain vibration-free within oil-filled or sealed housings.
Industrial Compressor & Servo Drives
Custom-built for tier-1 suppliers in Amata City Bien Hoa assembling automated machinery, compressors, and high-frequency servo motors. Multi-axis servo indexing handles irregular end-turn geometries without placing abrasive strain on delicate insulation sleeves.
4. Technological Shifts: Winding & Lacing Modernization in Vietnam
The manufacturing sector in Dong Nai is moving away from standalone machines toward networked smart manufacturing cells. To satisfy international carbon neutral directives and export requirements to the European Union (EU) and United States, motor assemblers are adopting three key technological vectors:
1. Direct Digital Tension Feedback: Rather than relying on purely mechanical friction brakes, modern double-side lacers incorporate electronic load-cell sensors. This provides closed-loop tension verification during every stitch, ensuring that high-slot-fill designs do not pinch wire insulation and result in short-circuit rejects downstream during the high-pot test.
2. Rapid Modular Tooling: As product life cycles shorten, the ability to switch tooling between differing core diameters (Φ80 mm to Φ140 mm) within 20 minutes is critical. Zunqi incorporates quick-release central mandrel clamps and pre-calibrated needle holders, enabling mixed-model production runs on the same factory floor.
3. Energy Efficient Drive Topologies: Leveraging permanent magnet synchronous servo motors (PMSM) for the main crankshaft and needle kinematics cuts total power consumption by 35% compared to older constant-speed asynchronous motors paired with electromagnetic clutch brakes.

Procurement FAQ
Frequently Asked Questions & Technical Inquiries
Answers to common questions from plant managers, procurement teams, and maintenance leads ordering machinery for Vietnamese operations.
What is the minimum order quantity (MOQ) and standard delivery lead time to Bien Hoa?
Our minimum order quantity is exactly 1 set for all standalone stator lacing, winding, and inserting machines. Standard tooling manufacturing and factory acceptance testing typically require 20 to 30 days. Shipping from Shenzhen or Guangzhou ports directly to Cat Lai Port (Ho Chi Minh City) takes only 3 to 5 days, followed by rapid customs clearance into the Bien Hoa industrial parks.
Does the machine support local 380V/220V 50Hz electrical grids in Vietnam?
Yes. We build the internal electrical cabinet, power transformer, and servo drives to match your facility's exact electrical supply. We provide 380V 3-phase 50Hz, 220V 3-phase, or 220V single-phase configurations. Please specify your workshop's voltage and air pressure (standard 0.4–0.7 MPa required) during technical drawing verification.
Can one double-side lacing machine process multiple stator stack heights?
Yes. If the stators share the same bore diameter (ID) and slot configuration, stack height adjustments (e.g., from 20 mm to 90 mm) can be completed in under 10 minutes by adjusting the vertical screw elevation scale and updating the parameter preset in the touch screen HMI. If the outer/inner diameters differ, we provide modular quick-change tooling sets.
What after-sales service and replacement part support do you provide to Dong Nai plants?
Every piece of equipment is backed by an unconditional 1-year mechanical warranty. We supply an emergency wear-and-tear kit with each unit (including spare lacing needles, hooking knives, pushers, and proximity switches). Our senior engineering desk responds within 9 hours, delivering bilingual English-Chinese wiring schematics, full operational video guides, and dedicated remote online support. Onsite engineer commissioning visits can be arranged for full-line turnkey projects.
How do we confirm our custom tooling before shipment?
Prior to shipment, customers send physical wound stator samples to our Dongguan factory. Our technicians perform full-speed trial binding runs, measure knot tensile stability, and produce comprehensive high-definition running videos for your engineering team's sign-off before crating.
