PROBLEM TO BE SOLVED: To provide a linear motor which can lower a cogging force sufficiently. SOLUTION: To a first permanent-magnetic pole P1 and a ninth permanent-magnetic pole P9, plate-shaped permeable bodies 17 are attached to each whole face opposed to adjacent permanent-magnetic poles. The permeable body 17 is composed of a silicon steel plate, and plays the role of changing the flow of the magnetic flux of a permanent magnet so as to lower the cogging force of a linear motor.
