Wind Turbine yaw and rotor brakers

The FY390 has been specifically designed to meet the exacting requirements of Wind Turbine yaw and rotor braking applications, where high braking and holding torques are required over long operational periods.FY390 provides reliable long term operation over extremes of environmental conditions, and simplified in-service inspection and maintenance for the duration of the Wind Turbine’s lifetime.Main Features• Hydraulically applied brake• Large brake lining area for reduced wear and operating temperatures• Grooved and tapered linings for improved performance and lifetime• Hydraulic drain ports to prevent oil contamination on the brake disc• Small air gap (between disc and lining) for minimum brake reaction time• Few moving parts for increase lifetime and easy maintenance• Suitable for horizontal or vertical installation• -40°C to 70°C operational range SpecificationFY390Brake typeActive hydraulic, split caliperPiston quantity & diameter, mm4 x 90Operating pressure (Max), bar172Clamp force (Max), kN213.5Tangential brake force (Max), kN170 (based on μ= 0.4)Oil volume per 1mm stroke, cm325Pressure connection port4 ports, ¼” B.S.P.Drain connection port2 ports, ¼” B.S.P.Lining typeDry-type powder metallurgyBrake lining width, mm102Allowable lining wear per side (Max), mm10Lining surface area (per caliper half), cm2 225Disc thickness, mm30Disc diameter (Min), mm1000Weight (caliper and linings), kg60Operational temperature range, °C-40 to 70
