This study examines the failure mechanisms of a three-phase AC induction electric motor with a closed body design, intended to provide IP protection, due to insufficient cooling under high-temperature conditions. Overheating at elevated temperatures adversely affects the motor's performance, leading to the deterioration of insulation materials and ultimately motor failures. The cooling performance of the motor, designed to rely on convection through its closed body design, has been evaluated in detail. During the experiments, temperature data were continuously recorded on both the inner and outer surfaces of the motor. The motor was operated at regular intervals under an 80% load, and its cyclic performance was monitored. The study also analyzed the effects of inadequate cooling on the motor’s cycle life using analytical methods. The research findings aim to provide strategic recommendations for design and operational processes to improve the reliability of electric motors, particularly those used in military and industrial applications.
