ELECTROMAGNETIC BRAKE

An electromagnetic brake conventionally comprises a disc (6) having opposing surfaces coated with a friction material (7), an electromagnet (8), an armature plate (9) arranged between the disc (6) and the electromagnet (8), and a plurality of compression springs pushing the armature plate (9) against the disc (6), the armature plate (9) being maintained in contact with the electromagnet (8) when it is in operation, and further comprises a sensor assembly (2) for measuring the movement of attraction of the armature plate (9) by means of an elastically deformable element placed on the brake in such a way that it has an initial deformation when the electromagnet (8) is not activated and undergoes a change in deformation as a result of said movement of attraction of the armature plate (9), sensor means configured to detect said change in deformation, and communication means transmitting the measurements made by the sensor assembly (2) to the outside of the brake.
