Transformer Coil Winding Machine – Low-Loss Precision for Efficient Transformers
Coil quality determines transformer performance. Shandong Bolt's winder ensures uniform winding via servo tension control and multi-layer insulation.
Tension Control
Magnetic brake + servo system (1-50N, ±0.1N):
Adjusts tension 0.01N/revolution for 1.5m max diameter.
Stops in 0.1s on wire breaks.
3000rpm speed with ±0.1mm wire arrangement (≤0.05mm layer gap).
Insulation Integration
Auto-feeds 0.05-0.5mm insulation paper (≤0.5mm alignment).
Wraps 10-50mm glass tape (20-50% overlap).
Sprays epoxy for coil ends.
Stores 1000+ parameters (≤10-minute changes).
Efficiency Data
10kV dry transformers achieve 8% lower no-load loss (2.3W/kg), DC resistance within ±0.5%. Integrates with testing (cuts scrap from 3% to 0.5%).
