Coils for Wind Generators & Wind Turbines
Anstee Coil Designs And Manufactures Custom Stator And Rotor Coils For Integration Into Wind Turbine Generators
Anstee Coil Technology designs and manufactures replacement and OEM stator coils for Doubly-Fed Induction Generators (DFIG) and Permanent Magnet Generators (PMG). We specialise exclusively in high-reliability electromagnetic coil components for OEM generator production and repair—we do not manufacture complete wind turbine assemblies.
Supplying customers globally across the renewable energy sector, our wind turbine coils support applications ranging from small domestic generators up to large-scale turbines of 1 MW capacity. Engineered to mitigate thermal breakdown during continuous grid excitation, our coils ensure maximum generator uptime and reliable power output in demanding onshore and offshore environments.

Designed for Reliability in Renewable Energy Systems
Wind turbines operate continuously under mechanical stress and environmental exposure. For this reason, our coil manufacturing processes focus on repeatability, durability, and performance stability.
Our self-bonding magnet-wire process ensures each turn of the coil adheres securely to the next, delivering improved vibration resistance and extended operational life.

Frequently Asked Questions
-
Yes. We manufacture drop-in replacement stator and rotor coils built to precise original manufacturer dimensions for rewinders, service contractors, and turbine refurbishment facilities across the UK and internationally.
-
We build coils using Class H (180°C) and Class C (200°C+) insulation systems designed to withstand continuous high thermal loads, rapid cycle changes, and harsh offshore or onshore environmental conditions.
-
We work directly from OEM engineering drawings, CAD files, or reverse-engineer physical coil samples provided from damaged, legacy, or obsolete generator units.
-
Lead times depend on material requirements and batch size, but we offer fast turnaround options for emergency repair work as well as scheduled production runs for ongoing OEM assembly lines.
-
Every coil undergoes rigorous quality control at our facility, including 100% surge testing, resistance checking, and high-potential (Hi-Pot) electrical testing to ensure full compliance with ISO 9001:2015 standards.
-
Yes. We process a wide range of oxygen-free copper conductors, including custom rectangular, square, and shaped magnet wire profiles tailored to optimise slot fill in generator stators.

Did you know...
The first windmills, the predecessors of today’s wind turbines, were used in china around 2000 bc. how appropriate then, that anstee coil technology now manufactures at its factory in modern china.
