<p>An inexpensive linear motor such that a magnetic small piece attracted to a permanent magnet can be easily removed and the man-hour of the assembling is reduced. The linear motor comprises field poles (3) composed of permanent magnets (2) so linearly arranged that the polarities of the poles are alternate, an armature core having teeth and slots with intervals with the field poles, and an armature winding composed of a coil and mounted in the slot of the armature core. The filed poles are parallelogram permanent magnets (2a), which can be a permanent magnet unit equivalent to multiple permanent magnets and fabricated by magnetizing a one-piece parallelogram permanent magnet blank in multipole.</p> |
