    • An electric motor 1 includes a first structure 4 including a magnetic pole row formed by a predetermined plurality of magnetic poles 4a arranged in a predetermined direction, a second structure 3 including an armature row disposed in a manner opposed to the magnetic pole row, for generating moving magnetic fields moving in the predetermined direction between the armature row and the magnetic pole row, and a third structure 5 including a soft magnetic material element row. The third structure disposed such that the soft magnetic material element row is positioned between the magnetic pole row and the armature row. A ratio between the number of the armature magnetic poles, the number of the magnetic poles 4a, and the number of the soft magnetic material elements 5a is set to 1:m:(1+m)/2 (m≠1.0).
    • 电动机1包括第一结构4,其包括由沿预定方向排列的预定多个磁极4a形成的磁极列,第二结构3包括以与磁极列相对的方式设置的电枢列,用于产生 在电枢列和磁极列之间沿预定方向移动的磁场以及包括软磁性体元素排的第三结构5。 第三结构被设置为使得软磁体元件排位于磁极列和电枢列之间。 电枢磁极的数量,磁极数4a与软磁体5a的数量之比设定为1:m:(1 + m)/ 2(m≠1.0)。
