摘要：This paper presents a method of fault prognostics and reliability estimation for DC motor using time series modeling procedure based on DC motor performance degradation data. DC motor performance degradation data are treated as a time series data and stochastic process are utilized to describe the degradation process for predicting long-term trend. A degradation test is processed for DC motor until they failed and the degradation data are collected for fault prognostics and reliability estimation. Degradation path of DC motors are predicted using time series analysis based on short time period degradation data. A comparison between the predicted failure time and the real failure time of DC motors is processed and the results show that the fault prognostics and reliability estimation of DC motors using time series analysis is effective.
