Earlier Period Fault Intelligent Diagnosis For Induce Motor Based On Model

The induce motor is the most common used device in driving many kinds of machinery and the industrial equipments. As power motor of industry and enterprise on a large-scale, the induce motor has usually been broken down in the mechanical and the electrical aspects owing to its heavy working loads as well as the bad working conditions, for example, the fault of stator core, insulation fault of winding, nose wire fault of stator, body fault of rotor, winding fault of rotor, electrical unbalanced fault, bearing fault and so on. Once the equipment doesn't run because of faults, not only can expensive motor itself be damaged, but security and the production of enterprise are under threat. That will bring about huge economic loss. Although the existing relay protection functions are perfect, protection systems will function up to or more than monitoring value. After the relay protection system function, motor is shut off suddenly. This will still result in the significant economic loss caused by the motor 's breakdown.In order to make the loss as low as possible, people are eager for...
