    • An adhesion structure of a motor that adheres a rotor having a first linear expansion coefficient and a magnet having a second linear expansion coefficient, which differs from the first linear expansion coefficient, with an adhesive agent. The adhesion structure includes a thickness determining groove extending parallel to the axis of the rotor and arranged on the rotor in order to determine the thickness of an adhesive agent layer, which is formed from the adhesive agent. The thickness determining groove absorbs shearing stress produced by the difference between the first and second linear expansion coefficients at a surface adhered to the magnet. This effectively suppresses exfoliation of the adhesive agent layer.
    • 使用粘合剂将电动机的粘附结构粘附在具有第一线性膨胀系数的转子和具有第二线性膨胀系数的磁体上,该磁体与第一线性膨胀系数不同。 粘合结构包括平行于转子的轴线延伸并布置在转子上的厚度确定槽,以确定由粘合剂形成的粘合剂层的厚度。 厚度确定槽吸收由粘附到磁体的表面处的第一和第二线膨胀系数之间的差产生的剪切应力。 这有效地抑制粘合剂层的剥离。

    • A position detecting apparatus for an actuator includes a linear movement mechanism in which a magnet is provided; a coil which is provided so as to face the magnet such that a magnetic field is formed between the coil and the magnet; and a drive shaft which is connected to the linear movement mechanism through a ball screw, and which is linearly moved in response to rotational movement of the rotor, the rotational movement being caused by energizing the coil; and a magnetic flux detection sensor which detects a change in magnetic flux of the magnet, the change being caused by the rotational movement of the rotor, and which obtains an amount of linear movement of the drive shaft based on the detected change in the magnetic flux.
