Claims

[Claims for Utility Model Registration] A stator having a plurality of magnetic pole teeth; a movable element having a plurality of magnetic pole teeth facing the magnetic pole teeth of the stator and movably supported by the stator; , a permanent magnet that is provided in the stator and forms a closed loop of bias magnetic flux through the magnetic pole teeth of the stator and the magnetic pole teeth of the mover that face each other; a plurality of drive coils that are sequentially excited to generate a magnetic flux having the same polarity as the closed loop of the bias magnetic flux when moving; and an elastic body that has both ends locked to the moving element near the poles of the permanent magnet. a magnetic body supported by a permanent magnet, which bypasses a portion of the bias magnetic flux when the drive coil is not excited and is attracted to the permanent magnet, and when the drive coil is excited, a closed loop of this exciting magnetic flux. A flat linear pulse motor, comprising: a locking member formed in parallel with the permanent magnet so that the attraction is released and the locking member is reset by the elastic body.
