PURPOSE: A permanent magnet motor is provided to use in a reciprocation required mechanism or device without any separate converting mechanism. CONSTITUTION: A permanent magnet motor comprises a stator(10), a rotor(20) inside the stator(10), and a rotating shaft(30) inside the rotor(20). The stator(10) includes a stator core(12), a pair of stator teeth(15), and coils(16) wound at the stator teeth(15). The stator teeth(15) are formed at a front and a rear reciprocative rotation areas(14,14') except for non-rotating area(13,13') at both of inner sides of the stator core(12). The coils(16) magnetizes the stator teeth(15). The rotor(20) includes a rotor core(22), and rotor teeth(23) protruded at the front and the rear positions of the rotor core(22). The rotor teeth(23) performs reciprocative rotation between the reciprocative rotation areas(14,14') depending on alternative magnetization of the stator teeth(15).
