Torsional Actuator Series ATA The torsional actuators ATA series are used to apply torques to standard samples, structures, components or finished goods. These torque-generating, high-performance cylinders are designed for applications with precise servo control requirement. - The hydrostatically supported, balanced double-vane rotor design ensure zero actuator backlash during revers testing and is well suited for high speeds and therefore particular suitable for dynamic materials and component testing. The hydrostatic bearing guarantees a hysteresis-free operation in the rated load range. Additional plastic coatings provides additionally emergency running properties when exceeding the maximum side loads and protect the damaging of the drive. The system pressure is 280 bars, the static rated torques are reached at 250 bars. The torsional actuators are in standard equipped with a high resolution, digital angle transducer (ADT) for angle measurement and closed-loop control. The servovalve ports will be made suitable for your required dynamic performance. Further mounting and fixtures are available including reaction brackets and fixturing. The standard torque range goes up to 80 kNm (80000 Nm) with 100° rotational angle. Solutions for higher torques and rotational angles can be provided as custom solutions.
