Embodiment Construction
[0020] The specific embodiment of the present invention provides a non-intrusive induction motor initial failure detection method, the method is as follows:
[0021] After the signal acquisition and conditioning equipment collects the voltage / current signal of the motor, it transmits the converted standard voltage / current signal to the data acquisition card, and then transmits the signal to the computer through wireless communication. The software operating system on the computer mainly includes Real-time signal acquisition, real-time algorithm analysis, and real-time display of results. At the same time, the software platform of the detection system is released to the cloud, allowing users to perform remote detection and monitoring. The voltage and current signals in this embodiment, that is, the voltage and current signals at the input terminal of the asynchronous motor stator, can be collected using current clamps, Hall sensors, etc., so there is no need to invade the motor ho...
