Braking is happened with the help of the pulling force provided by the magnetic field generated by the application of electrical energy. As a result of the disappearance of the magnetic field with the interruption of the electrical energy, the system is discharged again with the help of the spring mounted on the armature. The switching speeds in this system can be increased up to 10 times per second) by means of special electronic circuits. Since there are friction systems, the working gap may increase due to the wear that occurs over time. The working gap should be checked at appropriate intervals.
