| Abstract |
The present study aims to increase the amount of surface flux by changing the magnetic
directions of a spherical magnet (NdFeB) consisting of four poles. For this purpose, the magnetic
directions of quartile spherical slices constituting the spherical magnet are manipulated and their threedimensional
analyses are carried out by using finite-element method via Maxwell environment. The
analysis of the magnetic quartile spheres with four different magnetic directions are compared to the
each other, and then the quartile sphere with the best surface flux distribution is suggested for rotor
structure. It is clear emphasized that the induced torque of the spherical motor, in which such a rotor is
used, will be improved as well. |
