| titleOfInvention | Magnetizing condition monitoring device of synchronous motor and its method |
| abstract | The present invention enables to automatically monitor the magnetic magnetization state of the synchronous motor by using the back electromotive voltage waveform and the back electromotive voltage value of the back electromotive force generated in the excitation coil of the synchronous motor. To this end, the present invention provides an operator using an oscilloscope or the like. Unlike the aforementioned conventional method of manually checking whether the magnetic substance is normally magnetized by hand, the counter electromotive force of the sine wave generated in the excitation coil wound on the excitation pole of the stator is switched and output to the outside, and the counter electromotive force waveform of the output counter electromotive force is output. Automatic determination of abnormal magnetization due to magnetic defects of magnetic material based on the analysis result of the measured waveform of counter voltage, and excitation power supply system based on waveform analysis result and counter voltage value of counter voltage Automatic identification of abnormal magnetization due to defects Can dramatically reduce the time required to test the magnetic state of the group's savings can be realized increased productivity and production cost of the product, it can also significantly increase the accuracy (objective test) for magnetizing bad test. |
