The invention discloses a module-complementary-type flux-switching permanent magnet linear motor which comprises a primary part and a secondary part. The primary part and the secondary part are of convex electrode structures. An air gap is reserved between the primary part and the secondary part. The primary part comprises primary iron cores, permanent magnets, non-magnetic blocks and armature windings. Magnetic teeth are formed by the primary iron cores. A T-type unit is formed by each permanent magnet and the magnetic teeth on the two sides of the permanent magnet. The primary part comprises N*m T-type units, wherein the N is the number of coils in the windings of each phase, and the m is the number of the phases of the motor. A module is formed by i T-type units. The module-complementary-type flux-switching permanent magnet linear motor has the symmetrical complementarity, the manufacturing difficulty is lowered, waveforms of flux linkages and waveforms of counter electromotive force of the motor are symme
