ABSTRACT:
A reciprocating motor includes: an outer stator (4) in a support frame (2); an inner stator (6) disposed at the inner circumferential surface of the outer stator (4) with a certain air gap and mounted at the outer circumferential surface of a cylinder (16); a magnet (10) disposed to be linearly movable between the outer stator (4) and the inner stator (6) driven by the winding coil (8) due to move the piston (18); and the locking unit (30, 32), installed at the lateral face of the inner stator (6) for preventing the inner stator (6) from moving in an axial direction. Therefore, the reciprocating motor can improve reliability of a motor by preventing an inner stator (6) from moving in an axial direction by vibration caused by linear movement of the magnet (10).
