Latest Patents

Wenlong Zhu holds a patent for a "Motor Bearing Failure Diagnosis Device." This device is designed to diagnose faults in motor bearings effectively. It operates in a fault diagnosis mode, where a current signal acquisition unit captures real-time current signals from the motor. A residual signal acquisition unit then extracts harmonic signals from these current signals, removing both the fundamental and harmonic signals to obtain a residual signal. The fault feature extraction unit analyzes this residual signal in both time and frequency domains to extract a fault feature index of the bearing. Finally, a fault diagnosis model unit utilizes a trained bearing fault diagnosis model to perform pattern recognition on the fault feature index, enabling accurate diagnosis of the bearing's fault state.
