| Abstract: | In many kinds of electrical apparatus, the electromagnetic field, stress field and temperature field may exist simultaneously. Theoretically, it should be possible to unify the three kinds of field by the principles of analogy and duality. In this paper, a synthetic physical field equation is presented and expressed in terms of the generalized coordinates, speed and force. With the three dimensional eddy current electromagnetic fields of electrical machine as an example, the application of the synthetic equation with the numerical calculation by the finite element method are described in detail. The relationships between the synthetic physical field and the electromagnetic field in analogy and duality are listed with different coordinate systems. |
