ういずれか一方の当接側面に円状の窪み部を窪み
形成し、窪み部は窪み深さを１０μｍから３０μ
ｍの範囲に設けて成る交流電磁石。 A wound excitation coil, a fixed core fixedly fitted into the excitation coil, a movable core inserted into the excitation coil so as to be able to move toward and away from the fixed core, and a movable core inserted into the axial center of the fixed core. and a rod member that transmits the movement of the movable core to the outside, and a circular recess is formed on one of the contact sides to reduce the contact area between the fixed core and the movable core that contact each other. However, the depth of the depression should be between 10μm and 30μm.
An AC electromagnet installed in a range of m.
