... combustion products from the cylinder. In an EC – FPE shown in fig.1, however, the working fluid is re-circulated in a closed system. Heat is added and removed to the fluid using heat exchangers. The working fluid does not contain fuel and can now be any inert gas and the source of heat is independe ...

... railway, park’s transformation is used. A symmetrical 2-pole,3-phase winding on the rotor is represented by three coils A,B,C each of N effective turns and mutually displaced by 120 o as shown in fig a. Maximum values of mmfs Fa,Fb,Fc are shown along their respective phase axes. The combined effect ...

Detection and estimation of demagnetization faults in Permanent Magnet Synchronous Motors
... This paper reports the development of a robust non-invasive and computationally inexpensive system identification technique that is built upon formal-language-theoretic formulation, based on symbolic information. A central step in the proposed system identification method is discretization of the volt ...
