SKF applies for a health diagnosis patent for electric vehicle motor bearings to monitor the health status of motor bearings

According to news from the financial industry on October 28, 2024, information from the State Intellectual Property Office shows that SKF has applied for a patent titled "Health Diagnosis Method and System for Motor Bearings for Electric Vehicles", with the public number CN 118817306 A. The application date is April 2023.

The patent abstract shows that the present invention provides a health diagnosis method and system for motor bearings of electric vehicles. The method may include: collecting parameter data related to the motor bearing; preprocessing the parameter data to generate preprocessed parameter data; performing feature extraction processing on the preprocessed parameter data to obtain one or more features; and inputting the obtained one or more features into an anomaly detection model, and diagnosing the health status of the motor bearing based on the output of the anomaly detection model, wherein the parameter data includes the At least one of current data associated with the motor of the electric vehicle and rotor rotation data associated with the rotor of the motor.

The health diagnosis method and system of the motor bearing of the present invention can be used to monitor the health status of the motor bearing without the need to additionally set up a specific acceleration sensor in the electric drive system, thereby avoiding an increase in cost.
