To manufacture a brushless DC motor that can be driven by steady magnetic fluxes.

In general, magnetic fluxes in reverse directions repel each other, and conversely, the magnetic fluxes in the same directions attract each other. Thus, a bipolar magnetic material placed in steady magnetic flux oritented in one direction is unable to move because a force is neutralized due to a force in a reverse direction acting on each pole. As shown in the figure, however, single-pole magnetic charge having only either N or S pole has the reverse combination of the directions of the magnetic fluxes on the upper and the bottom surfaces in the magnetic flux in one direction. In the figure, magnetic fluxes are oriented in the same directions on the upper surface so that an attracting force in the upward direction is generated, and contrarily the magnetic fluxes are oriented in different directions on the lower surface so that a repelling force in the upward direction is generated. Thus, this magnetic single pole receives a force in one upward direction and can move in the magnetic fluxes. When this principle is utilized, a motor can be manufactured that is enabled to move efficiently in the magnetic fluxes oriented in one direction.
