(57) Security integrated system (100) for a motorised rolling gate, comprising the use
of a motor gear (10) and of a brake (50), that is automatically activated when the
motor gear is deactivated, characterised in that it comprises an encoder (20,21,30,31)
for detecting the current number of revolutions (10), the motor gear (10) being deactivated
when said number of revolutions exceeds a predefinable threshold. In particular, the
brake comprises a brake lining (20) which rotates with the same frequency as the motor
gear (10), characterised in that said encoder (20,21,30,31) is realised by means of
a first element (21) placed on the brake lining (20) and a second element (31) placed
on a non-rotatable support (30), in such a way that said first and second elements
(21,31) face each other at each revolution of the motor gear, thus sensing the execution
of each revolution of the same.
