Latest Patents

Shen Zhang holds a patent titled "Method for estimating bearing fault severity for induction motors." This invention presents a system designed to estimate the severity of bearing faults in induction motors. The system utilizes a set of filters and quantitative models tailored for specific fault frequencies. Upon receiving measurements of the stator current, the system extracts the first fault current using the first filter. It then determines the first mutual inductance variation from this fault current through the first quantitative model. The severity of the first type of fault is classified using a fault severity classifier. Similarly, the system classifies a second type of fault using a second filter and quantitative model. Ultimately, the system outputs the severity of one or both types of faults in the induction motor.
