WD-3500 CNC Vertical Winding Machine
The WD-3500 CNC Vertical Winding Machine is an advanced, high-precision assembly system specifically engineered for the heavy-duty winding and forming of generator rotor coils and high-voltage motor components. Equipped with a high-torque Mitsubishi servo motor system and Mitsubishi PLC control, it supports automated, continuous winding using round or flat copper wire. Featuring real-time magnetic powder tension control, precision ball screw transmission, and multi-axis synchronized feeding, the WD-3500 delivers millimeter-level alignment accuracy, uniform coil compactness, and maximum productivity for heavy industrial rotor manufacturing applications.

















Exceptional CNC Precision & Tension Control: Utilizes advanced CNC technology to achieve millimeter-level wire placement accuracy while real-time magnetic powder damper torque output prevents over-tightening or loose winding.
High-Efficiency Production Cycle: Features continuous, automated operation with intelligent sensing devices that eliminate manual positioning delays, vastly outperforming traditional manual or semi-automated winders.
Heavy-Duty & Robust Construction: Designed to handle heavy rotors up to 5,500 kg, equipped with high-strength alloy steel transmission gears, SKF bearings, and Shangyin linear guide rails for long-term reliability under continuous operation.
Intelligent Self-Diagnostics & Safety: Built-in CNC error-correction and real-time monitoring quickly diagnose and isolate system faults, minimizing machine downtime and protecting critical components.
User-Friendly Touchscreen HMI: Features a 10-inch Weinview touchscreen with intuitive graphical displays, memory storage for multiple winding recipes, and easy single-click program retrieval.
