1. What Is GW-7008L Large Magnetic Core Winding Machine?

new energy magnetic core coil winder

GW-7008L magnetic core winding machine independently developed by GREWIN INDUSTRIAL GROUP, specially designed for mass production of large-size toroidal magnetic core coils. Unlike , this equipment supports finished toroidal cores with an outer diameter up to 100mm, solving the winding difficulty of big ferrite magnetic cores that traditional small winders cannot process.

adopts a PLC human-machine interface control system, servo main motor drive, and hybrid stepping wire feeding motor, realizing full-process automatic winding from wire feeding to coil forming. It widely replaces manual winding and semi-automatic winding equipment, greatly improving production efficiency and coil consistency for electronics manufacturers.

3. Core Features of

Intelligent PLC HMI Control & Multi-recipe Storage: This fully automatic toroidal coil winding machine equips a touch screen PLC system, which can store dozens of different winding modes. Manufacturers can quickly switch production between multiple coil products without repeated parameter setting. Dual pulse identification technology is applied to wire storage and the winding process with a real-time detection function to avoid wire breakage or missing turns.

Modular Quick-Change Fixture Design: Users can independently replace the magazine and guide wheel according to different toroidal core specifications. The machine body adopts a compact road-mounted aluminum profile structure; all transmission components use well-known international brand standard parts, ensuring smooth operation, high precision, and long service life.

Customizable Multi-Type Winding Process: We support customized winding methods for special product demands, including counter winding, secondary wire storage, layered dense winding, and other special winding crafts to meet the production requirements of power transformers, automotive inductors, and communication chokes.

toroidal transformer manufacturing equipment

will automatically stop running and display specific alarm information on the touch screen, effectively reducing defective coil rate and protecting machine components from damage.

Low Operation Skill Requirement: The control logic is simple and humanized. New operators can master basic operation within 1–2 hours without professional electrical knowledge, helping factories reduce labor training cost and rely less on skilled winding workers.

4. Working Principle & Operation Showcase

GW-7008L large toroidal core winding machine

1. Manually load the toroidal magnetic core to the fixture station;

2. The machine automatically feeds enameled wire via a stepping motor wire storage structure;

3. Servo motor drives the winding head to rotate at adjustable speed, laying wire with programmable line spacing;

4. Real-time detection monitors wire tension and winding turns;

5. Finish winding and stand by for next core loading.
