Zero-Max Wind Turbine Torque Limiters protect wind turbine gearboxes and generators against peak loads, reversing torques, and grid short events. They are suitable 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° without falling out of tolerance. Designed and engineered for application requirements ranging from 4 to 50kNm with a temperature range of -40 to 80°C, this bi-directional functioning torque limiter has no limitations.
Designed for onshore and offshore turbine drive trains with capacities up to 5MW, these Zero-Max Torque Limiters have 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 drive train applications.
