摘要： A non-contact sensor for sensing a rotational position of a rotating object is provided. A ring-shaped permanent magnet magnetized in the axial direction is sandwiched between two pairs of magnetic plates from above and below. Two pairs of upper and lower protruded magnetic substance portions are provided between the upper and lower magnetic plates at opposite outer ends thereof. Magnetic sensitive devices are inserted in air gaps between the two pairs of upper and lower protruded magnetic substance portions. A magnetic flux generated from the ring-shaped permanent magnet is substantially concentrated to the protruded magnetic substance portions and passes the magnetic sensitive devices. The amount of magnetic flux passing each magnetic sensitive device is substantially proportional to the rotational angle of the ring-shaped permanent magnet. The rotational position of the ring-shaped permanent magnet and hence the rotational position of a rotating shaft supporting the ring-shaped permanent magnet can be sensed in a non-contact manner as a signal output from the magnetic sensitive device. Since the magnetic flux is effectively concentrated to positions where magnetic sensitive devices are attached, a non-contact rotational position sensor having high accuracy and high sensitivity can be obtained.
摘要翻译：提供了用于感测旋转物体的旋转位置的非接触传感器。沿轴向磁化的环形永久磁铁从上下方向夹在两对磁性板之间。两对上，下突出的磁性体部分设置在上下磁性板之间的相对的外端。磁敏装置插入两对上下突出的磁性物质部分之间的气隙中。从环形永久磁铁产生的磁通量大致集中到突出的磁性体部分并通过磁敏装置。通过每个磁敏装置的磁通量的大小与环形永久磁铁的旋转角成正比。环形永磁体的旋转位置以及支撑环形永久磁铁的旋转轴的旋转位置可以以非接触的方式被感测为从感应装置输出的信号。由于磁通量有效地集中在安装了敏感元件的位置，所以可以获得具有高精度和高灵敏度的非接触式旋转位置传感器。
