Abstract
High permeability material plates used to construct the stators and the rotor of a motor are formed of the same material, thus reducing the number of fabrication processes and material cost. Also, the rotor containing permanent magnets is cylindrical and two stators are arranged around the inner circumference and the outer circumference of the permanent magnets, respectively, thereby increasing efficiency.
