Claims

[Claims for Utility Model Registration] The device includes a driving body and a driven body that are relatively linearly movable in the direction of one moving axis, and the driving body is formed with a predetermined pitch in the direction of the moving axis so that each A magnetic pole array consisting of a plurality of magnetic poles around which an excitation coil is wound is provided, and the driven body is provided with a plurality of teeth formed at a pitch different from the magnetic poles in the direction of the moving axis, corresponding to the magnetic pole array of the driving body. In a single-axis electromagnetic drive device in which a tooth row is provided, the driving body is provided with a plurality of magnetic pole rows whose pitches in the direction of the moving axis of the magnetic poles are different from each other, and the driven body is provided with a plurality of magnetic pole rows of the driving body. Correspondingly, a single-axis electromagnetic drive device is characterized in that a plurality of tooth rows having different pitches in the direction of the tooth movement axis are provided.
