PROBLEM TO BE SOLVED: To decrease ripple of mover thrust by finding the optimum magnetizing direction and arrangement of permanent magnets on a stator side, making the flux density distribution of a permanent magnet train into a rough sinewave, and approximating counter electromotive force induced by a mover coil to a sinewave, thus reducing cogging torque. SOLUTION: This linear synchronous motor includes a primary mover having a coil and a secondary stator in which a plurality of permanent magnets are disposed along a straight line, and moves the mover along the secondary side stator linearly by exciting the coil. A plurality of the permanent magnets are disposed adjacent to each other, and the magnetizing directions of the permanent magnets adjacent to each other are shifted by 90 deg. in each moving direction and orthogonal direction of the mover.
