This text carried on introduction and analysis for ten kinds of structures and operate priniple that familiarly spread a feeling machine and was juxtaposed to enumerate some related datas as references and familiarly spread a feeling machine to carry on fault diagnosis and analysis to the fraction, and introduced some examination methods. Pass vs these structures that spread a feeling machine and work the analysis of priniple and fault, tally up these spread a feeling machine in the working hours whether needs to apply electr
