Abstract
It is an object of the present invention to provide a linear pulse motor which can increase the number of ampere conductors and attain a multi-phase configuration with a uniform magnetic circuit without increasing the length in the axial direction. The linear pulse motor includes a stator composed of two stator cores having 2.multidot.k.multidot.m salient poles disposed radially in an inner peripheral surface, a permanent magnet held between the stator cores and having a thickness such that a distance between centers of small stator teeth is (N+0.5) times of a tooth pitch and stator windings wound to bestride two salient poles of the stator cores, and a mover including a cylindrical core. Small teeth in the form of ring are disposed in the mover or the stator at equal pitch in the axial direction and small teeth disposed in the axial direction are formed of laminated stator iron plates or mover iron plates each rotated by {(360.multidot.n)/(2.multidot.k.multidot.m)} degrees. The small teeth form k sets each set including m small teeth forming tooth tip portions and m small teeth forming tooth bottom portions which are arranged in order of the description.
