This paper presents a comparative analysis of a transfer field machine (TFM) and a poly-phase induction machine (IM) with central focus on the inductance matrix of both machines . The two machines belong to two different classes of machine and quite different in physical configuration. In this analysis , the self inductance matrix of the two machines are derived and both shown to be independent of the rotor angular position. However , the mutual coupling inductance in both cases are dependent on rotor angular position which varies with time. For the transfer field machine , in addition to rotor angle dependence, it also depends on the difference between the direct - and quadrature- axes reactances. In both machines, when state variables namely voltage and flux linkage equations, are transformed to arbitrary qdo reference frame, a new set of voltage and flux linkage equations are obtained with inductance values , no longer dependent on the rotor angular position that varies with time ; and this of course is of great advantage in the analysis of both machines.
