Bonfiglioli 700TW Series planetary gearbox

Bonfiglioli's 700TW Series is its new-generation Yaw Drive planetary gearbox designed to provide high radial/thrust load capacity and efficiency.

Featuring an integrated motor-inverter, the series is designed for performance in low duty cycles. It is also 8% lighter than its predecessor, thanks to its simplified design.

Designed to reduce the lifetime cost of a wind turbine plant, the gearbox can provide improved energy consumption. It delivers good control both as a motor and as a generator, and can also be used as a battery backup solution. The series is easily integrated with Bonfiglioli sensors to provide technicians with real-time data on the turbine system (speed, load and current) as well as maintenance indicators (ie, temperature, vibration, etc).

In addition to the 700TW, Bonfiglioli also has permanent magnet synchronous AC motors, suitable for use in Pitch and Yaw systems. The motors are available in totally enclosed or fan ventilated executions, and with a fail-safe electromechanical brake.

Through more than 30 years of collaboration with leading wind turbine OEMs, Bonfiglioli has developed dedicated wind turbine solutions. For the last five years, it has served as a member of APQP4Win.
