Abstract

Elevator accidents occur frequently, brake function failure is one of the main factors. If the brake function fails, it will cause the elevator to run out of control. Therefore, the effectiveness of the brake function is closely related to the safety of the occupants. The electromagnet is the most critical components of elevator braking system. In this paper, combined with an electromagnetic brake iron core damping case, by taking various analytical methods, such as external assessment, chemical composition analysis, and microstructure, analysis the cause of the electromagnetic brake iron core damping. Based on the analysis results, it can be inferred that brake electromagnet brake iron core damping faults is related to iron core anomalies adhesive wear. Meanwhile, as the iron core is an abnormal ferromagnetic material (DT4), this will increase the iron core on the adsorption of ferromagnetic chips.
