    • A magnetic circuit structure, such as a motor, is provided with: a rotor having rotor-side magnetic poles formed on the outer surface; and a stator having stator-side magnetic poles formed on the inner surface. The magnetic circuit structure has an air gap between the outer surface of a rotor-side magnetic pole and the inner surface of a stator-side magnetic pole in the location where the rotor-side magnetic pole and the stator-side magnetic pole face each other. At least one pair of a protrusion and a recess is created so that the outer surface of a rotor-side magnetic pole and the inner surface of a stator-side magnetic pole face each other through the air gap in the direction of the actual line of the rotation axis, and each pair of a protrusion and a recess has two or three steps in the direction of the radius around the rotation axis.
    • 诸如电动机的磁路结构设置有:转子侧磁极,形成在外表面上; 以及具有形成在内表面上的定子侧磁极的定子。 在转子侧磁极和定子侧磁极彼此相对的位置,磁路结构在转子侧磁极的外表面和定子侧磁极的内表面之间具有气隙 。 创建至少一对突起和凹部,使得转子侧磁极的外表面和定子侧磁极的内表面沿着实际行的方向通过气隙彼此面对 旋转轴和每对突起和凹部在围绕旋转轴线的半径方向上具有两个或三个台阶。
