Industrial use

Sectional doors and rolling doors

400 Vac | three phase

Up to 40 ㎡

Integrated device that guarantees maximum precision during the automation manoeuvring steps

Oil lubricated motors guarantee the maximum lifespan and high performances


400 Vac | three-phase

400 Vac gear motor with encoder, quick release and 1/20 reduction rates | Plastic box that makes wiring the motor easier, thanks to the position of the front clip connector and the possibility of reaching three different positions with the wiring | Equipped with absolute encoder that permits the regulation of the positions of the opening and closing limit switches on the door directly from the control unit | Quick plug-in connection for quick and easy installation | Two accessories are available for chain drives with gear speed reduction rates 1:1 (off-axis motor installation) or 1:1.8 (torque or speed multipliers) | Maximum safety guaranteed during rapid release phases, thanks to a micro-switch that cuts the power supply to the motor | Oil lubricated reductions with hardened steel screw and bronze gears guarantee high performance, maximum reliability and silent operation
