Low maintenance electromechanical actuator range improved

Complementing the existing Diakont range, INMOCO has introduced the new Diakont DA78 series electromechanical actuator. The DA78 uses the same roller screw technology as the DA67, DA99 and DA140 actuators and offers size and performance levels between the DA67 and DA99 units. All DA actuators have an integrated motor and roller screw to provide superior performance in a compact space envelope.

The roller screw design provides a large contact surface for converting rotary torque to linear motion with minimal backlash. This makes the DA actuators best in class in terms of reliability, lifetime, load capacity, tolerance to shock loads, absence of vibrations and output efficiency.

The permanent magnet synchronous motors used in the Das are designed to provide precision accuracy in highly dynamic force and motion applications, while also delivering exceptional reliability. Patented lubrication ports mean the actuators can be re-lubricated without having to be disassembled or removed from their host machines.

The DA series provides performance in the ranges of: continuous force (stall rating) up to 22,300N (5,013lbf); nominal backlash 0.1mm (0.004”); lead accuracy 0.025mm/300mm (0.001”/ft) and speeds up to 833mm/s (32.8”/sec).

The DA78 is available in three formats, the DA78-22, DA78-25 and DA78-35. These provide peak forces of 9000N to 13,000N; dynamic load rating from 20,700N to 33,500N; stall ratings of 3,500N to 6,250N; maximum speeds of 150mm/se or 300mm/sec; a thread lead of 2.5mm or 5mm and minimum strokes of 75mm or 150mm.

All Diakont DA Series actuators are constructed from ruggedised components designed to operate reliably in harsh conditions. Aside from operating in temperature extremes, Diakont units are also built to withstand the shock and vibration associated with the most demanding applications. Units rated at IP66 protection levels are also available.
