Study on Static Magnetic Characteristics of a Switched Reluctance Motor with 12/10 Poles under Different Operation Modes

This paper mainly presents the static inductance and flux linkage characteristics of a switched reluctance motor (SRM) with 12/10 poles when it respectively works as a six-phase motor and a three-phase motor. Two excitation types, single phase excitation (SPE) and double phase excitation (DPE), are separately applied to the two operation modes. The comparison between self and mutual inductances under different excitation types show that the proportion of the mutual inductance between two adjacent phases in its self inductance is much larger than that of non-adjacent phases for six-phase mode, and it is also larger than that of three-phase mode. Finally, the simulations are experimentally proved by using an indirect flux linkage measurement method. A good consistency between the simulated and measured results is shown.
