Example Embodiment
[0024] Example 1: Please refer to Figure 1-2 , A method for fault diagnosis of asynchronous motors based on deep learning, including the following steps:
[0025] A. Build a simulation experiment platform for asynchronous motor operation; the simulation experiment platform is mainly composed of a computer, load controller, asynchronous motor, tachometer, current sensor, acceleration sensor, NI data acquisition card, etc. The faults that the plan can diagnose include rotor imbalance, stator winding fault, stator winding broken turns, bearing fault, rotor bending, and rotor broken bars. In order to ensure the diversity of experimental data, a variety of different working conditions will be simulated by changing the speed and load conditions of the asynchronous motor.
[0026] B. Collect the current signal and vibration signal of the simulated motor fault state; the input sample to be collected should contain all the characteristics of the fault signal as much as possible. Since the ...
