摘要
Although torque enhancement in multiphase induction machines using harmonic current injection has been addressed in the literature, a detailed assessment of the effect of this enhancement on the design parameters of multiphase machines with different numbers of phases is needed. This paper addresses this topic by performing a detailed comparative study of harmonic injection torque enhancement on multiphase machines with different numbers of phases. Sets of identical dimension and volume rotors differing in their value of the bar skew angle were designed to operate with the various stator designs in order to facilitate the comparative evaluation. A mathematical approach is also introduced to enable the derivation of equivalent multiphase machine parameters based on an existing one. In addition to a detailed finite-element-analysis verification of the results, time domain MATLAB simulations are used to verify the mathematical modeling. The results provide a means to assess the extent to which such harmonic injection may be beneficial by quantifying torque enhancement as well as torque density for various multiphase machines.
