Electromechanical linear actuators designed around an integrated motor

Sourced from Diakont in San Diego, California, DA actuators are utilised 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

The components within the DA actuators contribute to industry leading precision, power, and reliability. The advanced roller screw design, for instance, provides a high-performance method for converting rotary torque to linear motion.

With a high level of surface contact and minimal backlash, the DA unit roller screws are ultra-reliable and have a long working life while offering a large load capacity, tolerance to shock loads, absence of vibration, and output efficiency.

DA actuators incorporate integrated Permanent Magnet Synchronous Motors (PMSM) that maintains 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.

DA actuators can produce a continuous force of up to 22300N (5013lbf) and speed of up to 833mm/s (32.8in/s. Standard units have a nominal backlash of less than 0.1mm (0.004in), and zero backlash options are also available. The lead accuracy is 0.025/300mm (0.001in/ft). Constructed from a robust design and manufacturing process, DA actuators withstand temperature extremes (-40 to +100ºC), shock and vibration and are available with IP66 ratings.

Suitable for a wide range of applications, DA actuators are equipped with patented 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 necessary to meet particular applications. The company is represented exclusively in the UK by INMOCO of Daventry, which also offers a wide range of compatible motion control components, along with bespoke engineering capabilities, applications expertise, test and calibration.
