700T series

Yaw and Pitch Drive with Torque Limiter.

700T series, Gearmotor & gearboxes for wind turbines

For both Yaw and Pitch drive applications, Bonfiglioli has created a torque limiter which significantly reduces downtime in the case of stopping the transmission of wind turbines when peak torque has been reached and also reduces maintenance costs.

Technical data

Rated Torque range
8000 ... 120000 Nm

Peak Torque Range
5000 ... 300000 Nm

Reduction Ratios
1:600 ... 3000

Key Features of Torque Limiter
External to gearbox* for fast and easy replacement - no longer necessary to replace the entire gearbox
Limits peak of torque to avoid failure
Shuts down gearbox if torque limit is reached
Fully interchangeable with older gearboxes - can be included in replacement drives for greater long-term reliability and reduced costs

Gearbox Configuration
Flange mounted
Output shaft: with integral pinion (type: F, N, U)
Rugged design
High torque capacity
Output shafts supported by high load capacity bearings

Applicable AC motors
Compact motors and brake motors M/ME series
IEC motors and brake motors BN/BE series

Main Brake Motor Features
DC and AC brake

Main brake features
AC/DC rectifier
Double disc brake
Microswitch
Thermal sensors

(*) The torque limiter is located inside an easily removable and replaceable cartridge, which is integrated into a VF 110 worm gear.  It is only possible in a right angle solution.
