The hydraulic slide valve is an important hydraulic component in the hydraulic system, which is widely used in the aviation and rail transit fields. The hydraulic slide valve is very sensitive to oil contamination, often resulting in stuck due to increased levels of contamination, thus affecting the normal operation of the entire hydraulic system. Carrying out the reliability analysis and quantita...Show More
Electric motors act as the backbone of industrial development. Their reliable and safe operation is essential to various industries. At present, motor fault diagnosis based on current signatures has progressively gained favor thanks to their noninvasive nature. This review summarizes recent advances in motor current signature analysis (MCSA) for fault diagnosis. First, motor diagnostic background ...Show More
Motor is the pillar of industrial development, and the motor diagnosis method based on current signal analysis is gaining popularity due to its non-invasive nature. In order to solve the incipient fault diagnosis problem of induction motor based on current signal, a method based on Frequency-domain Teager Energy Operator(FTEO) and Square Envelope Spectrum(SES) is proposed. To begin, a notch filter...Show More
