Fully Automated Cobot-Assisted OBC Coil Winding System

Winding Equipment We Trust — Tested in Our Own Production

This machine is capable of performing a comprehensive sequence of operations for OBC coils, including multi-winding interlacing, wire taping, interspersing, and post-winding insulation wrapping. The entire winding process is executed fully automatically by the equipment. By resolving issues inherent in manual winding—such as wire stacking, uneven wire alignment, and damage to the insulating film—the system significantly enhances the level of automation and operational efficiency, reduces labor costs, and creates substantial value for the enterprise.

❖ The motion controller is integrated with a specialized closed-loop intelligent fine-tuning winding control technology. Its patented closed-loop wire-guiding sensor utilizes digital sampling technology, offering robust anti-interference capabilities, precise control, and superior wire-laying performance.

❖ Closed-Loop Tension Control: Ensures uninterrupted operation and high equipment utilization rates, while maintaining stable impedance values and high overall reliability. The precision-aligned winding arrangement reduces material waste, facilitates rapid adjustments, and minimizes maintenance costs.

WHY WISRSUN?

❖ The motion controller is paired with a specialized closed-loop intelligent fine-tuning dense-winding control technology. Its patented closed-loop wire-laying sensor utilizes digital sampling technology, offering robust anti-interference capabilities, precise control, and superior wire-laying performance.

❖ Closed-Loop Tension Control: The controller is capable of programming and monitoring every dual-motor active servo tensioner within the system, and monitors and uploads the tension status of the entire production process in the form of data.

Our standard MOQ is 500 pcs for most coil types. For first-time customers or prototype evaluation, we accept small trial orders of 10-50 pcs. MOQ may vary by product complexity. Contact us for a specific quote.

Yes. Samples are available within 5-7 business days after engineering confirmation. A nominal sample fee applies, which is credited toward your first mass production order.

You can email drawings such as PDF, DWG, or STEP files, or fill out our inquiry form. If you do not have drawings, a written description or physical sample is also acceptable.

We can wind wire as fine as 0.01mm using Zongheng CNC precision winding machines with automated tension control.

Yes. Our special-shaped coil series handles non-circular and irregular geometries. Submit your drawings and our engineering team will assess feasibility.

Standard options include bare copper wire, enameled copper wire, and Litz wire. Custom alloy or coated wire options are available on request.

Yes. Provide your target inductance, frequency, and DC resistance requirements, and we will calculate and wind to specification.

WIRESUN is ISO 9001 certified. Products can ship with test reports and COA. Third-party inspection can be arranged upon request.

All coils are wound on CNC machines with precision control. Each production batch undergoes electrical testing, including inductance, DCR, and impedance checks.

Standard documentation includes packing list, commercial invoice, Certificate of Analysis, and electrical test report. RoHS/REACH documents are available upon request.

We ship worldwide. Regular destinations include Southeast Asia, Europe, the Americas, the Middle East, and Russia. Express and sea freight options are available.

Standard terms are 30% T/T deposit upon order confirmation and 70% balance before shipment. L/C is accepted for larger orders, and Western Union is available for sample fees.

Standard products usually take 15-20 business days. Complex custom coils generally take 20-30 business days. Final lead time is confirmed at quotation stage.
