摘要： Plurality of air gaps are formed in a torus-shaped stator body of the resolver. If a straight line were drawn from a center point of the stator body toward the outside in the radial direction of the stator body and the straight line were rotated 360 degrees about the center point, the straight line would intersect with at least one of an inside air gap and an outside air gap. Therefore, magnetic flux (i.e., noise caused by magnetism) that has penetrated from the outer peripheral surface side of the stator body will always pass through a portion of the stator body that is to the outside in the radial direction of the air gaps, such that a large portion of the magnetic flux is eliminated by the air gaps.
摘要翻译：在旋转变压器的环形定子体中形成多个气隙。如果从定子体的中心点沿着定子体的径向向外侧引出直线，并且直线绕中心点旋转360度，则直线将与内部的至少一个相交气隙和外部气隙。因此，从定子体的外周面渗透的磁通量（即由磁性引起的噪声）将总是通过定子体的沿气隙径向的外部的一部分，例如通过气隙消除大部分磁通量。
