Claims

[Scope of utility model registration request]

It includes a stator with magnetic pole teeth arranged in a flat plate shape at equal pitches, a mover consisting of two cores with windings and a permanent magnet part, and the two cores of the mover have magnetic pole teeth of the stator. Each has two magnetic pole tooth groups consisting of magnetic pole teeth with the same pitch, and the phase difference between the magnetic pole tooth groups in the same core is 1/2 pitch, and the phase difference between the magnetic pole tooth groups between different cores is 1/2 pitch. is 1
The four magnetic pole teeth groups of the mover are arranged in parallel along the moving direction of the mover so as to have a pitch of 74, and the four groups of magnetic pole teeth of the mover as a whole are 0 pitch, 1/4 pitch, and 1/2 pitch with respect to the stator magnetic pole teeth. , linear stepping motors arranged to have a phase difference of 3/4 pitch.
