<p><P>PROBLEM TO BE SOLVED: To provide an axial gap type motor in which a reluctance torque is increased without remarkably decreasing a magnet torque, and problems due to magnetic saturation of a back yoke hardly occurs even when the back yoke is provided. <P>SOLUTION: The axial gap type motor 1a is provided with: a rotor 20a as a field magnet rotating in a circumferential direction centered at a rotary shaft 91a; and a stator 30a as an armature opposite to the rotor 20a with a distance in the direction of the rotary shaft 91a. The rotor 20a is provided with: a permanent magnet 22a having a magnetic pole face 225a exhibiting a magnetic pole alternately changing along the circumferential direction; and reluctance cores 23a guiding a magnetic flux generating the reluctance torque. In the axial gap type motor 1a, in the rotor 20a, the reluctance cores 23a are unevenly provided in a diameter direction while using the permanent magnet 22a as a reference, so that an area of the reluctance cores 23a or a center angle is expanded. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
