Abstract
An elevator brake includes a frame part including an electromagnet; a moving armature movably supported on the frame part; at least one energy storage, such as a work spring, arranged between the frame part and the moving armature; a friction lining associated with the moving armature and fitted to engage a braking surface with a normal force originating from the at least one energy storage, to brake movement of an elevator car or to hold the elevator car standstill; and a sensor system including one or more sensors mounted into the elevator brake and adapted to sense one or more operational parameters of the elevator brake and/or to directly measure normal force of the friction lining.
