| Abstract: | The theory that electricity is drawing the electric motor was applied to analyze the practical case, in which the electric motor for lifting of a certain crane burned up repeatedly.Some reasons that might cause the failure were listed,and the essential problem was finally found out,based on which several comprehensive solutions were presented.The proper plan for technical reform was chosen in terms of the study of feasibility. |
