【Abstract】 A new method of extracting rotor bar breaking fault features is introduced.It can be applied in the conditions of low signal to noise ratio which often happens at the beginning of fault so that the fault can be discovered earlier and a new and effective method for diagnosing the rotor bar breaking fault can be offered.Results of numerical simulation show that the approach has a good prospect in project appliance.更多还原
