Why the Industry Is Moving Toward Automatic Winding Machines
Higher Design Complexity
Modern SMPS transformers use multi-layer windings, parallel wires, and multiple insulation stages that demand high precision.
Consistent Quality Requirement
Automatic machines ensure repeatable winding quality, stable electrical parameters, and uniform insulation across batches.
Reduced Labor Dependency
Automation minimizes reliance on skilled winding operators and eliminates human fatigue and variation.
Higher Production Output
Automatic winding delivers faster cycle times and higher daily production compared to manual methods.
Lower Rejection & Rework
Digital process control significantly reduces winding defects and scrap rates.

Machine’ Operation Video
Typical Transformer Winding Cycle
-
Automatic Bobbin Loading
Empty bobbin is loaded manually or via optional auto-loader. -
First Winding Operation
Selected wire and sleeve are automatically inserted, winding is completed, and insulation tape is applied. -
Second Winding Operation
A different wire and sleeve combination is selected automatically, followed by winding and taping. -
Third & Fourth Windings (If Required)
Additional windings are completed as per the programmed recipe. -
Automatic Unloading
Finished transformer bobbin is unloaded to tray or conveyor for next process.
Step-by-Step Operational Breakdown
1. Bobbin Loading
- Manual loading or optional automatic loader
- High-precision fixture ensures stable alignment
- Supports single or multi-bobbin configurations
2. Program Selection
- Operator selects transformer model via touchscreen HMI
- Programs are pre-configured based on winding data
- No mechanical changeover required
3. Dual ARM Synchronized Winding
Both ARMs work simultaneously to complete:
- Primary winding
- Secondary winding
- Feedback winding
- Auxiliary winding
Supported winding types:
- Layer winding
- Section winding
- Interleaved winding
- Bifilar / Trifilar winding
- Tap winding
4. Multi-Axis Servo Control
