  • Solution for monitoring an elevator brake
    Patent number: 10717629
    Abstract: The present invention relates to a machinery brake for an elevator. The machinery brake comprises a frame part comprising an electromagnet and an armature part, wherein the machinery brake further comprising an inductive proximity sensor mounted to one of the following: the frame part, the armature part and a target mounted to the other of the following: the frame part, armature part. The inductive proximity sensor and the target are mounted with respect to each other so that in a normal state of the machinery brake the target resides within an operational area of the inductive proximity sensor and in an abnormal state of the machinery brake the target resides at least partly outside the operational area of the inductive proximity sensor. The invention also relates to a method therein.

  • Solution for compensating an effect of temperature change in a proximity sensor in a machinery brake of an elevator
    Patent number: 10479646
    Abstract: A machinery brake of an elevator includes a frame part including an electromagnet, an armature part, an inductive proximity sensor indirectly mounted to one of the following: the frame part, the armature part, and a target mounted to another of the following: the frame part, armature part. The machinery brake further includes, for establishing the indirect mounting: a temperature change compensation device mounted between the inductive proximity sensor and one of the following: the frame part, the armature part. Some aspects relate to a method for compensating a change in switching point of an inductive proximity sensor.
