• Auto cutting

• Auto indexing

• Continuous and discontinuous winding

• Supports 2-pole / 4-pole / 6-pole coil winding.

• Parameters set via HMI with adjustable wire tension control.

Coil Inserting Machine

• Automatically inserts coils and wedges into stator slots.

• Reduces labor and increases accuracy and consistency.

• Suitable for copper and aluminum wires.

• Compatible with polyester film wedge rolls of fixed width and thickness (as per customer specs).

Lacing Machine

• PLC-controlled with flexible lacing patterns:

• Slot-by-slot lacing

• Interval lacing

• Fancy decorative lacing

• Available models:

• Single-station lacing machine

• Double-station lacing machine

• Horizontal lacing machine

• Quick tooling change, stable operation.

Forming Machine
