Through to study the domestic and foreign paper about the fault diagnostic method of asynchronous motors, the topic has been established from research of the minor faulty analysis and its faulty equivalent model about asynchronous squirrel cage induction motor. At the same time, we design the experimentation and confirmatory measurements in the laboratory.In view of faulty characteristic of asynchronous squirrel cage induction motor, we enumerate and analyzed the faulty model about the vibration fault and the stator current fault. Moreover, we enumerate each kind of faulty reason. Base on the faulty characteristic of asynchronous motor, we discuss the faulty cause of asynchronous motor and corresponding method of fault diagnosis.Model-based fault diagnosis of asynchronous motor, we enumerate model of the well-found motor, and analyze that it become void in fault. Meanwhile, we discuss a new motor model, which is about the squirrel cage in the minor fault.In the process, we design the experimentation and confirmatory measurements in the laboratory. In order to achieve a precision experimentation, we discuss diagnostic methods which include the testing devices, the testing methods, the measuring instruments, the measuring points, the sensors and the data processing, thus we obtain the effective fault...
