Abstract (en)
[origin: EP1457643A2] The electronic safety system to avoid an overspeed in the event of a shaft breakage has a longitudinally extending measuring optic light guide (13) rotating with the shaft, with a light source (18) provided on the input side, and an optic sensor (19) on the output side. An interruption of the optic light guide effected by a shaft breakage and the receiving of altered light signals at the optic sensor via an electronic computing and control unit (20,21) detects the shaft breakage and interrupts the energy supply to the driving side of the shaft.
