Abstract A novel two-phase doubly-salient permanent magnet motor with new windings configuration(TDSPM) is proposed in this paper. The structure of TDSPM is the same to that of well-known three-phase doubly salient permanent magnet machine(DSPM). But it is different from the latter in that two adjacent turns in a phase winding span three stator salient poles and only two phases winding is formed. The physics model of the TDSPM with 1.8kW output power is derived analytically. On basis of the finite element analysis, the feature of proposed machine is investigated, including air-gap flux distribution and flux linkage of per phase winding. Results show that there is less leakage flux around the idle stator poles for TDSPM than DSPM. Further, the bipolar and asymmetrical flux linkage for the proposed TDSPM is revealed, which has a steeper slope than that for the DSPM. Hence, it exhibits the higher flux rate, better torque density, materials and space utilization compared with the DSPM. Finally, the dynamic analysis is carried out with the derived physical model. It is shown that there is no zero torque zones, so starting is not a problem for the proposed TDSPM. There still exists the torque ripple due to the configuration with the doubly salient pole.
