Wind energy. Built for the nacelle.
Yaw, hydraulic and cooling motors with C4H anti-corrosion paint for decades at height.
Background: representative footage
The duty
Reliable at height, in all weather.
A wind turbine turns the wind into rotation through its blades, and a generator turns that into electricity. Around the generator, several smaller electric motors keep the turbine working: turning it into the wind, driving its hydraulics and cooling it.
EMPD supplies these motors for wind applications.
Applications
What the duty demands
- Corrosion protection (C4H paint) and IP66
- Brakes and anti-condensation heaters
- 690 V windings and decades of service
