Abstract: A rotor with four axially stacked rotor cores, and a plurality of field magnets interposed between them. Each rotor core includes a rotor-side claw-shaped magnetic pole. Each rotor-side claw-shaped magnetic poles are respectively extending from and formed on each rotor core at equal angle intervals. Tip end surfaces of the first and third rotor-side claw-shaped magnetic pole abut against or are closely opposed to each other axially. Tip end surfaces of the second and fourth rotor-side claw-shaped magnetic poles abut against or are closely opposed to each other in the axial direction. The plurality of field magnets are magnetized in the axial direction such that the field magnets causes the first and third rotor-side claw-shaped magnetic poles to function as first magnetic poles, and cause the second and fourth rotor-side claw-shaped magnetic poles to function as second magnetic poles.

Abstract translation: 具有四个轴向堆叠的转子芯的转子和插在它们之间的多个磁场磁体。 每个转子芯包括转子侧爪形磁极。 每个转子侧爪形磁极分别以相等的角度间隔从每个转子铁心延伸并形成。 第一和第三转子侧爪形磁极的尖端表面轴向抵接或相互紧密地相对。 第二转子侧爪状磁极和第四转子侧爪形磁极的前端面在轴向上抵接或紧密相对。 多个场磁体沿轴向磁化，使得磁场磁体使第一和第三转子侧爪形磁极用作第一磁极，并且使第二和第四转子侧爪形磁极 用作第二磁极。
