<p>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.</p> |
