摘要

Abstract

This study focuses on the "Goodrich 44316-1-1 hoist" as the research subject

systematically analyzing four major fault modes in its motor system: Burnout of power resistors on the filter board

Fragmentation of rotor magnets in the motor

Fracture of connecting pins on the bridge arm capacitor board and Damage to operational amplifiers

Through in-depth analysis of the failure mechanisms

corresponding technical solutions and preventive measures are proposed.
