利用感应电机滚动轴承轴电压进行早期齿轮故障检测

Condition-based maintenance of electric drivetrains relies on effective fault feature revelation. Instead of mounting extra sensors in the drivetrain, the motor itself can be utilized as a built-in fault detector. The shaft voltage of electric motor is essentially coupled with the drivetrain dynamics, thus, can support rotating machinery fault detection. In this work, the theoretical basis and pra...
