摘      要：In order to solve the problem of asymmetric bidirectional flux control capability in hybrid excitation machine,a novel structure called dual consequent hybrid excitation synchronous(DCHES)machine is presented in this ***,the analysis of back-EMF for the machine with complex electromagnetic structure such as DCHES machine should utilize 3-D finite element analysis(FEA),which will require huge resources and computing *** order to avoid using 3-D FEA to analyze the back-EMF of complex structure,an analytical method of calculating back-EMF is presented in this *** electromagnetic field in 3-D space can be simplified as a 2-D field by dividing the 3-D field into several simple zones,the resultant effect equals to the summation of every single 2-D field s *** to electromagnetic theory,the analytical formula of back-EMF is obtained on the basis of Fourier *** influence of main parameters on back-EMF waveform under sine and trapezoidal flux distribution is discussed *** theoretical result shows that the trapezoidal air-gap flux distribution would generate a sine ***,the presented analytical method is verified and evaluated with experimental results.
