MONITORING OF BRAKE

摘要

The monitoring of a brake is disclosed. The brake includes first and second braking surfaces and a magnetizing device arranged to move the braking surfaces to an open state, in which the braking surfaces are separated from each other, and to a closed state, in which the braking surfaces are connected to each other. During the monitoring of the brake, the time is measured that elapses from the change in the magnetic field caused by the magnetizing device to the shift of the braking surfaces from one state to another.
