Mechanism operated by Brushless DC (BLDC) Motors which has:

A Rotor with Permanent Magnets and a stator with windings

A Brushes and commutator have been eliminated and the windings are connected to the control electronics, so motor is less noisy

Potentially cleaner, faster, more efficient, less noisy and more reliable

Rotor has permanent magnets vs. coils thus lighter less inertia: easier to start/stop

Linear torque/current relationship smooth acceleration or constant torque

    Ambient Temperature:

    Working temperature: from -10° C min to 50° C max

    Storage temperature: from -20° C min to 60° C max

    Maximum vertical load allowed on top track:

    115 kg, Center Opening & 115 kg x 2, Telescopic

    Self Learning & Speed Profile Parameters in brief:

    During first installation, or at the time of changes in functional parameters, drive will go for Self Learning Test to measure the span of opening. Then it will store that data in its memory, and set the operational profile.

    The speed is adjusted by programming software, we’ve calibrate that parameter as company default value; also it has some range to adjust different speed of opening/closing profile curve.

    Obstruction Sensing Value:

    110 % to 300 % of rated torque
