Detection of AC Motor Magnetic Torque for Breakdown of Inclined Shaft Winding System |
|
|
Abstract: |
The precise method for calculating and detecting the AC motor magnetic rotor flux and torque is developed by changing the high-nonlinear to linear model via coordinate conversion. The knowledge base of pseudo expert system is proposed. Derailment fault diagnosis system is presented by using the magnetic torque on line. The site test results are given. |
