Reliability analysis of elevator brake electromagnet

Brake electromagnet is the core equipment of elevator braking system, and its reliability directly affects the safe operation of elevator and the personal safety of passengers. In this paper, the reliability of an in-service elevator brake plunger electromagnet is tested and analyzed. The results show that the minimum pull-in voltage on the sample side of the brake is too high, and the maximum release voltage and working temperature are normal. In the process of use, the plunger action at both ends is not synchronized, that is, there will be an obvious time difference when the drum on both sides releases the braking force.
