Abstract:

© 2017 IEEE. By using the powder metallurgy technology and the magnetic isotropy characteristic of the soft magnet composite (SMC) material, various kinds of permanent magnet machines can be designed and fabricated easily. However, the torque density of permanent magnet machines with SMC cores are generally lower than those with silicon steels, with the traditional machine topology, since the permeability of the SMC is much lower than that of silicon steels. To develop the potential of SMC in high-performance drive applications, we propose a novel axial flux claw pole machine (AFCPM) with SMC cores. To eliminate the unwanted axial force in the AFCPM, the two-phase configuration concept is adopted, both the configuration of the stator-rotor-stator and the rotor-stator-rotor AFCPM are designed, analyzed, and compared. Based on the 3-D finite-element method, it can be found that the AFCPM with the configuration of the stator-rotor-stator can have very low cogging torque and torque ripple; moreover, since the rotor is in between of the two stator cores, the unbalanced axial force has been decreased greatly. On the other hand, the two-phases AFCPM with the rotor-stator-rotor can have the highest torque density and efficiency.
