High Performance Electric Actuators The DA Series of electromechanical linear With a high level of surface contact and and manufacturing process, DA actuators actuators, available in the UK through minimal backlash, the DA unit roller screws withstand temperature extremes (-40ºC INMOCO is designed around an integrated are ultra-reliable and have a long working to +100ºC), shock and vibration and are motor and roller screw, a compact life while offering excellent load capacity, available with IP66 ratings. configuration that provides excellent tolerance to shock loads, absence of performance. vibration, and output efficiency. Suitable for a wide range of applications, DA actuators are equipped with patented Sourced from Diakont in San Diego, California, DA actuators are utilized in demanding applications in automation and robotics, resistance welding, machine tool positioning, semiconductor manufacturing, packaging machines, and many other fields. They are used as alternatives to hydraulic and pneumatic cylinders, doing away with the need for power packs and compressors DA actuators incorporate integrated permanent magnet synchronous motors (PMSM) that maintain exact accuracy in highly dynamic and/or high force applications. Furthermore, efficiency is achieved because the motor's rotating output shaft is directly coupled to the actuator's drive mechanism. in-situ lubrication ports which are designed so that re-lubrication, the only actuators' only required maintenance, is carried out without having to disassemble the actuators or even remove them from their mounting. Diakont offers a broad range of standard actuators to suit most requirements. Special actuator configurations and modifications are produced when The state-of-the-art components within DA actuators can produce a continuous necessary to meet particular applications. the DA actuators contribute to industry force of up to 22300 N (5013 lbf ) and The company is represented exclusively in leading precision, power, and reliability. speed of up to 833 mm/sec (32.8 in/sec. the UK by INMOCO of Daventry, which also The advanced roller screw design, for Standard units have a nominal backlash offers a wide range of compatible motion instance, provides a high-performance of less than 0.1mm (0.004 in), and zero control components, along with bespoke method for converting rotary torque to backlash options are also available.
