摘要： A stator core (11) is mounted to a stationary member (22) and electric wiring on the stator side is carried out, to thereby assemble a first sub-module (20), and a rotor core (12) is mounted to a rotary member (21) and electric wiring on the rotor side is carried out, to thereby assemble a second sub-module (30). Thereafter, the first and second sub-modules are assembled together, with the stator core and the rotor core opposed to each other, whereby a separable transformer is assembled. A guide member (27), having first and second reference faces defining reference positions in diametrical and axial directions of the rotation shaft (21), respectively, is provided in the rotation shaft (21) rotatably supported by the stationary member and mounted with the rotor core. Mounting positions of the cores are determined with use of the guide member, thereby precisely setting a center position between the cores and a gap length g.

摘要： A rotation sensor includes a rotor rotatable together with an automotive steering shaft, a conductive band formed on the rotor, a magnetic coil/core unit fixed near the rotor, the unit having a core body and an exciting coil, and a rotation angle detection circuit electrically connected to the coil. The width of the band gradually increases along a half-circumference of the rotor and then gradually decreases along the remaining half-circumference of the rotor, as viewed in the rotating direction of the rotor. The detection circuit applies an alternating signal to the coil. As the rotor is rotated with the alternating signal applied to the coil, the band causes the impedance of the coil to change in accordance with the rotation angle of the rotor, and based on the impedance change, the detection circuit detects the rotation angle of the rotor, that is, the steering shaft.
摘要翻译：旋转传感器包括与汽车转向轴一起旋转的转子，形成在转子上的导电带，固定在转子附近的磁性线圈/芯单元，具有芯体和励磁线圈的单元和旋转角度检测电路电连接到线圈。沿着转子的半周，带的宽度逐渐增加，然后沿转子的旋转方向观察，沿着转子的剩余半周逐渐减小。检测电路向线圈施加交替信号。当转子以施加到线圈的交变信号旋转时，该带使线圈的阻抗根据转子的旋转角度而改变，并且基于阻抗变化，检测电路检测转子的旋转角度转子，即转向轴。
