Blog Article

This study aims to improve the torque performance and manufacturability of axial-flux permanent magnet (AFPM) machines.Hence, we propose a novel AFPM machine that employs a soft magnetic composite (SMC) core with tooth-tips constructed by a one-pressing process and die.In this paper, the proposed AFPM machine is compared to two conventional AFPM machines using an SMC core.One of them has open-slot structure without tooth-tips.

Another model employs an SMC core with tooth-tips pressed by a conventional pressing process that requires multiple operations and dies.As a result Pre Workout Boosters of the comparison, the proposed AFPM machine realizes a much higher torque than the two conventional machines.Additionally, the manufacturability of an SMC core with tooth-tips pressed by the proposed method is superior to the conventional one because the proposed structure can be realized by the one-pressing process and die.Furthermore, two prototypes of the proposed AFPM machine and the conventional one with an open-slot structure are fabricated, and then, they are compared by experiments.

Consequently, the proposed AFPM machine achieves a 15.7% higher torque than that of the conventional machine using an open-slot structure.Finally, this paper presents an improved design of an AFPM machine with SMC cores using the proposed pressing process.As a result, the proposed AFPM realizes a 20% larger torque than that Whips of a conventional model employing an open-slot structure.
