Abstract: The objective of this paper is to investigate the load characteristics of a novel tangential PM Doubly Salient Hybrid Excitation Machine (DSHEM). The tangential PM DSHEM has potential advantages to offer excellent performance which abandon the axial magnetic circuit and additional air gap of DSHEM. The structure features of the tangential PM DSHEM were discussed first. Then 2-D finite element analysis software was developed and the air-gap flux densities with load were researched. After that, a prototype motor was presented and the external characteristic varied with excitation currents and rotational speeds were obtained.
