The present study investigated the design, simulation, and manufacturing of a new coreless stator axial‐flux permanent‐magnet motor. In addition, to magnets with magnetisation along the motor axis, the new structure included magnets that were magnetised circumferentially and buried at the rotor surface. The electromagnetic design of the conventional axial‐flux motor and the new motor was evaluated according to nominal values and design equations. In this regard, the number of poles and coils, as well as the outer diameter of both motors were assumed to be identical. It was observed that the axial length of the new motor is shorter than the conventional axial‐flux motor. Simulations were continued through comparing the motors in terms of air‐gap flux density, torque, and back electromotive force using the transient finite element method. A comparison of the results showed that the new motor had a better performance than the conventional axial‐flux motor. Subsequently, the new motor was manufactured and tested; the experimental results proved to be close to those presented in the analytical section.

Axial flux permanent magnet (AFPM) motors are suitable options for solar powered vehicles due to their compact structure and high torque density. Furthermore, certain types of APFM machines may be configured without stator cores, which eliminates associated losses and cogging torque and simplifies the manufacturing and assembly. This paper examines two machine designs for use in the solar powered vehicle of the challenger class-a single rotor, single stator conventional AFPM machine, and a coreless AFPM machine with multiple stator and rotor disks. Response surface methodology (RSM) is utilized for the systematic comparison of the conventional and coreless topologies and to select the optimum designs among several hundreds of candidates. Designs with minimum losses and mass producing required torque with larger air-gap are favored. The performance of the selected designs have been studied via 3D finite element analysis (FEA). The FEA parametric modeling methodology is validated by measurements on three AFPM machines of the conventional and coreless type. Index Terms-Axial flux permanent magnet machines, coreless, multi-disk, solar powered electric vehicles, finite element analysis, winding factor, response surface methodology, design of experiments.
