Wind Turbine Torque Limiters

Zero-Max’s torque limiters protect wind turbines against peak loads, reverse torques, and grid shorts. Shaft-mounted to the generator shaft, our wind turbine torque limiters are factory-set to slip at specific torque settings, ranging from 4,000 to 50,000Nm.

This functionality prevents the transmission of excess torque from the generator to the gearbox in the event of grid fault or disturbance and protects both the generator and the gearbox against premature failure. This allows for low voltage grid ride-through capability and helps wind turbine manufacturers meet strict grid code requirements.

Our torque limiters are engineered to function in unison with our composite disc wind turbine couplings to provide effective protection for all turbine drivetrain components. Together, Zero-Max’s wind turbine drivetrain components provide the most reliable performance solution in the wind energy industry.
