| Popis: | 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. |
