A linear motor achieves both a decrease in pulsation and an increase in propulsion with a 6n teeth structure provided with: a first mover for holding permanent magnets arranged longitudinally; a first stator having 6n teeth that are arranged so as to oppose the first mover and 6n windings that are wound on the respective teeth; a second mover holding permanent magnets longitudinally; a second stator having 6n teeth that are arranged in the longitudinal direction so as to oppose the second mover and 6n windings that are wound on the respective teeth The permanent magnets opposing each other in the first mover and the second mover are disposed with a phase difference of π/2 in the moving direction of the two movers, and electrical currents with a phase difference of (1+6m)π/3 or (2+6m)π/3 are supplied to the windings opposing each other in the first stator and the second stator.
