Abstract: Systems, methods and computer program products calculate the life remaining in a machine, such as an electric motor, or the life remaining in individual components within a machine. Life remaining calculations are based on information collected from multiple sources, including operator input data, historical data, and lookup tables. Using this information the remaining useful life of the machine is calculated based on quantitative data, standard design life limits and on reliability analysis such that continuous historical parameter data is not required to analyze or assess the life of the machine.

Abstract: The reliability and remaining time before failure for electric motor systems and the like is determined with an ascertained statistical confidence based on continually monitored system parameters and a database comprised of historical failure mode/cause and repair data concerning the same motor and/or similar motor systems. A computational process is followed that relies upon hierarchical failure-tree structures, Weibull probability distributions and directed causal networks and which updates the probabilities and models used to forecast the remaining time before system failure based on the monitored parameters. Motor system operational parameter data is continually monitored at the site of the motor system and up-loaded via wireless or other communications network to a remote computer system where a database is maintained and reliability analysis is performed.
