Zero-Max Wind Turbine Torque Limiters protect against peak loads

Zero-Max Torque Limiters are proven for slip torque values ranging from 4,000 to 50,000 Nm.

Zero-Max Torque Limiters are proven for slip torque values ranging from 4,000 to 50,000 Nm.

Zero-Max Wind Turbine Torque Limiters protect wind-turbine gearboxes and generators against peak loads, reversing torques, and grid short events. They are ideal as an upgrade replacement for existing wind turbines and for OEM applications.

The Zero-Max torque limiter is engineered to mount directly to the generator shaft to avoid resonance concerns allowing for ease of installation. Once installed, the torque limiter operation occurs internally and requires no readjusting or maintenance. The automatic re-engagement capability allows for continual 20-year operation with no manual intervention to reset the limiter after slip events.

Zero-Max’s torque limiters have been proven and tested to 5,600 slip torque events of 30 degrees without falling out of tolerance. Designed and engineered for application requirements ranging from 4kNm to 50kNm with a temperature range of -40° to 80° C, this bi-directional functioning torque limiter has no limitations. Utilizing a Zero Max composite disc coupling with the Zero-Max torque limiter provides the finest solution with the highest level of overall protection for all of today’s wind turbine drivetrain requirements.

Designed for onshore and offshore turbine drivetrains with capacities up to 5 MW, these Zero-Max Torque Limiters have extreme endurance in a lightweight package. Easy to install either on the production floor or in the cramped up-tower environment, they operate equally well in new OEM turbines or existing drivetrain applications.
