Abstract: The full-pitch winding multiphase double salient permanent magnet (FMDSPM) machine appears to have several performance advantages of high space utility, high power density, lower cost and low torque fluctuation. With the distributed winding structure, the equivalent magnetomotive force of the phase winding of FMDSPM machine is quite different from that of the concentrated winding. A FMDSPM machine with 6/4 structure was taken as the example, the magnetic equivalent circuit (MEC) model with dividing the air gap into five sections was present and permeances for each sections are formulated. The solution was carried out to get some static characteristics such as flux linkage, back electromotive force as well as the cogging torque. The validity of the model was verified by comparing to the results of finite element analysis.
