Induction heating for wind turbine manufacturing
Induction heating and wind power form a virtuous circle: clean electricity generated by wind turbines can power the induction systems that build them. ENRX is a leading supplier of induction heating solutions to the wind energy sector, delivering everything from giant turnkey plants — with up to three coils working simultaneously — to mobile, flexible equipment for field service work.
Why wind turbine manufacturers use induction heating
- Handles components at extreme scale, including slewing rings over 5 metres in diameter
- Delivers controllable, repeatable heat for safety-critical structural and drivetrain parts
- Available as fixed factory installations or portable equipment for on-site tower and foundation work
Bearing, gear and slewing ring hardening
- Hardening of bearing and slewing rings
- Hardening of gearbox shaft and bearings, and generator bearings
- Hardening of pitch bearings and gear teeth
- Hardening of raceways, ball tracks and gears at virtually any dimension
- Gear hardening of yaw drives and slewing rings
- Hardening of giant slewing rings exceeding 5 metres in diameter
Shrink-fitting
- Shrink-fitting of main shaft bearings and sleeve rings
- Stator house shrink-fitting of yaw motors and pitch motors
Brazing of electrical components
- Brazing of terminal ends on high-voltage cables
- Brazing of stator and rotor windings
- Brazing of components in high-voltage step-up transformers
Pre-heating and welding support
- Pre-heating before welding of tower baseplates and tower rings
- Portable Ventac systems for pre-heating, post-heating and shrink-fitting, including quick-wrap heating blankets for field welding jobs
Bolt heating and cable work
- Bolt heating on tower foundations
- Induction heating of wind turbine cables
