Abstract

The current feature for motor carried with natural mixed eccentricity and bearing fault is merely focused even though it is very important for motor online diagnosis. Considering both of the air-gap length change and torque vibration caused by bearing fault, the stator current expression were deduced for mixed eccentric motor. The new current characteristic frequencies for motor with bearing fault and mixed eccentricity were obtained. Finally, a series of simulation studies were conducted, the results show that the new eigenfrequencies are real and useful for online diagnosis of those motor in service.
