頼性の高い操作を行うことができる利点を有する。As explained above, the present invention consists of a columnar rod and an annular body into which the rod is fitted loosely, both of which are made of magnetic material, and the outer surface of the rod is provided with teeth at a constant pitch in the axial direction. Further, teeth of the same pitch are formed on the inner surface of the annular portion into which the rod of the annular body is loosely fitted, and either the rod or the annular body, that is,
Excitation that divides the teeth that will become electromagnets into at least three groups, and makes the intervals between the groups different from the above-mentioned pitch, and also makes the intervals different from each other, and further enables on/off control for each group to make it an electromagnet. Since the means is provided, the rod or annular body can be responsively moved according to the command value from the control button of the excitation means, and the overall structure can be made extremely compact. Therefore, it has the advantage of being able to perform highly reliable operations when used in aircraft flap control and the like.
