For years, Nabtesco says it has been developing hydraulic equipment, engine accessory and fuel systems, and flight control systems for several Japanese Defense Agency programs. Now the company, a manufacturer of hydraulic drives and controls, is expanding into energy-efficiency and environment-friendly products. Hence, it has started a new business involving the application of hydraulic equipment for yaw drives on 1-MW wind turbines. The drive units for wind turbines consist of yaw drives for pointing a turbine into the wind, and pitch drives for controlling the inclination or pitch of turbine blades in response to wind velocity.
