| Abstract: | The mechanical characteristic of electromotor and the principle of wavelet multi resolution are studied.By means of material experiment,it shows that wavelet analysis with local feature well in the time frequency domain is very effective in mechanical fault diagnosis of electromotor,which can provide a valid analysis means for other mechanical fault diagnosis. |

| Keywords: | wavelet analysis eigen frequency electromotor fault diagnosis |
