Efficiency Estimation Of Electric Machine Using Magnetic Flux Circuits
نویسندگان
چکیده
Improving efficiency of electrical machine is of paramount importance to optimization of operational and resource management. Efficiency method which do not account for iron loss could undermine the effective efficiency estimation. This paper simulates the efficiency variations of electric machine in both transient and steady state, magnetic flux linkages are used instead of the traditional current method, though also in d-q axis. Only magnetic flux linkages are used in an arbitrary reference frame while machine efficiency in various reference frames namely; rotor, stator and the synchronous reference are investigated. Results are compared with measured quantities and excellent estimations are obtained. Keyword: electrical machine efficiency, machine losses, magnetic circuit, generalized machine equation

Differential global surface impedance (DGSI) model, a rigorous approach, has been applied to the analysis of three dimensional plasmonic circuits. This model gives a global relation between the tangential electric field and the equivalent surface electric current on the boundary of an object. This approach helps one bring the unknowns to the boundary surface of an object and so avoid volumetric...
