The elevator rotor manufacturing unit, as a core equipment of the elevator traction machine, has extremely high requirements for processing stability, necessitating reliability analysis. After confirming the hierarchical division and fault criteria of the rotor manufacturing unit, fault analysis was conducted on ten functional subsystems, and corresponding FMECA (Failure Modes, Effects, and Criticality Analysis) results were obtained. Finally, the prominent fault issues of the rotor manufacturing unit were summarized, and appropriate improvement measures were proposed. This study provides a strong basis for the reliability management and improvement of the rotor manufacturing unit. It identifies the main sources of failure, and based on the characteristics of the failure sources and related fault results, suggestions for design, manufacturing, and maintenance are provided.
