Drive Unit for Wind Turbines

The drive unit for wind turbines consists of a "yaw drive (yaw gear)" to change the direction of the wind generator following the direction of the wind and a "pitch drive" to control the inclination of the blades of the wind generator in response to the velocity of the wind. Nabtesco's drive units for wind turbines are based on advanced hydraulic equipment technology and they have been favorably received in the market for their higher durability, reduced weight, compactness and other features.
