A novel low-speed axial-flux-modulated motor is presented. The proposed motor breaks the traditional design rule which stipulates that the pole-pair numbers of the stator and the rotor must be the same. Special iron segments in the airgap are used to modulate the magnetic field. It has the merit of having high power density at low speed. It can be fitted into very limited space such as inside the wheel rim of electric vehicles. Compared with those of radial-flux-modulated motor, its manufacturing and assembling process are simple and easy. Its performance is compared with those of a radial-flux-modulated motor using two-dimensional and threedimensional finite-element methods.
