Axial-ux-modulated motors (AFMMs) with two pole-slot combinations are presented and analyzed quanti- tatively. They all have new topology structures, and their design rules differ from those of the traditional machine. The concentrated stator windings are designed to reduce the end length and copper losses; therefore, the efficiency of the motors can be improved. Special iron segments in the air-gap are used to modulate the magnetic field. The two proposed AFMMs have 36 stator slots and 30 stator slots, respectively, and the pole-slot combinations are 6 poles for 36 slots and 4 poles for 30 slots. This paper focuses on the comparative performance analysis of the two proposed AFMMs by using the 3D time-stepping finite element method. The ux linkage, air-gap ux density, electromotive force waveforms, output torque, core losses, and efficiency of the two proposed AFMMs have been investigated.
