چکیده :

In this paper, the dual-rotor dual-stator axial field flux-switching PM (DR-DS-AFFSPM) topology is presented, designed, and analyzed to improve the cogging torque and torque ripple. The 12-pole dual-stator has been located on both sides of the 10-pole internal dual-rotor and phase-group concentrated-coil windings for the aim of increasing fault-tolerant capabilities. The 3D finite element method (3D-FEM) analysis is utilized for determining the main characteristics, such as the magnetic field distribution, the flux-linkage, back electromagnetic force, the cogging torque, the output torque, the torque ripple, and the losses in the internal dual-rotor DS-AFFSPM motor. A comparative analysis in the same condition is thoroughly made of the designed topology and related topology in literature, in order to determine the most effective structure such as traction applications based on torque density, torque ripple, cogging torque, and efficiency. The results show that, the low-cogging torque, low-torque ripple, high-torque density, and high-efficiency, of the internal dual-rotor DS-AFFSPM topology is a suitable candidate for traction applications.
