nT 25 Rotary actuator
A torque of 25 Nm plus various positioning times and a BLDC motor with a wide-range voltage input and controller as standard across the series make the nT 25 a reliable actuator for a multitude of applications in process plant engineering.
BLDC motors offer an unparalleled advantage with regard to endurance characteristics in the form of a long service life far in excess of that possible with brushed commutator motors.
Moreover, they do not generate particles through brush abrasion; this effectively avoids lubricant contamination and can thus prevent gear performance deteriorating over time.
The design of the housing made of die-cast aluminium in combination with permanently lubricated gearing ensures their suitability for use in a broad range of temperatures and harsh operating environments.
