Title: Jisheng Dai: Innovator in Motor Bearing Diagnosis

Introduction

Jisheng Dai is a notable inventor based in Hunan, China. He has made significant contributions to the field of motor diagnostics, particularly in the area of bearing failure detection. His innovative approach has the potential to enhance the reliability and efficiency of motor systems.

Latest Patents

Jisheng Dai 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 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, diagnosing the fault state of the bearing.
