II. Transformer Core Winding Machine

This fully automatic toroidal winding machine is specially designed for winding toroidal cores made using CRGO electrical silicon steel. All the operations are controlled by Panasonic PLC control system with fully closed-loop control, including clamping, fixing, pressing, winding, cutting, welding, releasing.

5 Servo motors are equipped to drive the operations including

  • Non-stop cutting
  • Cutting down CRGO strips with max. thickness of 0.35mm (with reducer)
  • Winding spindle (with reducer)
  • Flapping & ejecting finished cores
  • Feeding & clamping strip to pin on spindle

Main Features of Transformer Core Winding Machine

  • 1. The operations are automatically made, including feeding, winding, cutting, welding, releasing.
  • 2. PLC control and HMI panel makes the operations simple and convenient.
  • 3. Adopting laser welding causes little or no damage to CRGO strip.
  • 4. Motorized lift table can be adjustable to adapt to different toroidal core diameters.
  • 5. Separate chillers are specially designed for control cabinet, and main electronic components.
  • 6. Carbide cutting blade provides more than 3 million cuts
  • 7. CRGO strips can be automatically decoiled.
