GWAT-80HM Fully Automatic Three-Phase Common Mode Transformer Hook Winding Machine Now Available

 

[Tianjin, China] - [July 15th,2026] - [Tianjin Grewin Group] today announced the launch of the GWAT-80HM, a fully automatic three-phase common mode transformer hook winding machine engineered to improve production speed, winding precision, and consistency for manufacturers of common mode transformers, chokes, and EMI filter coils.

 

What Is the GWAT-80HM?

The GWAT-80HM is an automatic hook winding machine designed specifically for three-phase common mode transformers. It automates the wire feeding, hook winding, and coil-forming process, replacing manual or semi-automatic winding methods that are slower and more prone to inconsistency.

 

Common mode transformers are widely used in EMI/RFI filters, power supplies, motor drives, and industrial electronics to suppress electromagnetic interference. As demand for these components grows across the electronics manufacturing industry, equipment like the GWAT-80HM addresses the need for higher throughput without sacrificing winding accuracy.

 

Key Features of the GWAT-80HM

  • Fully automatic operation - from wire feeding to hook winding, minimizing manual intervention and labor cost
  • Three-phase common mode transformer compatibility - purpose-built for three-phase coil configurations
  • High-speed hook winding technology - increases output per shift compared to manual winding
  • Precise tension control - ensures uniform coil winding and reduces defect rates
  • Repeatable, stable production quality - supports consistent electrical performance across production batches
  • Reduced labor dependency - helps manufacturers manage rising labor costs and skilled-labor shortages

Why Automatic Winding Matters for Common Mode Transformer Production

Manual winding of three-phase common mode transformers is labor-intensive and can introduce variability in turn count, tension, and coil placement - all of which affect the transformer's inductance and EMI suppression performance. The GWAT-80HM's automated hook winding process is designed to reduce this variability, helping manufacturers meet tighter quality tolerances while increasing production capacity.

Typical Applications

  • The GWAT-80HM is suited for manufacturers producing:
  • Common mode chokes and transformers
  • EMI/RFI filter coils
  • Power supply and inverter filter components
  • Industrial and automotive electromagnetic compatibility (EMC) components

Frequently Asked Questions

What is a common-mode transformer winding machine? A common mode transformer winding machine is industrial equipment used to wind wire around a transformer core to form common mode chokes or transformers, which are used to suppress electromagnetic interference in electrical circuits.

What does "hook winding" mean? Hook winding is a winding method in which a hook-style mechanism guides and wraps the wire around the transformer core, commonly used for toroidal or ring-shaped common mode transformer cores that require precise, consistent wire placement.

Is the GWAT-80HM suitable for three-phase transformers specifically? Yes. The GWAT-80HM is engineered specifically for three-phase common-mode transformer winding, distinguishing it from single-phase winding machines.

Who uses this type of machine? Manufacturers of EMI filters, common mode chokes, power electronics components, and companies producing electromagnetic compatibility (EMC) solutions for industrial, automotive, and consumer electronics use automatic hook winding machines like the GWAT-80HM.
