Abstract: Disclosed herein is a linear reciprocating flux reversal Permanent Magnetic (PM) machine in which stators are provided with air gap sections and interpole sections and magnets are inserted into a mover. The linear reciprocating flux reversal PM machine, comprises a pair of stators arranged to be opposite to each other, the stators each having two coils wound in opposite directions, and air gap sections and interpole sections alternately arranged on inside portions of the stator in a crosswise direction of the stator with the air gap sections of a first stator opposite to interpole sections of a second stator; a mover disposed between the stators to be reciprocated therebetween, the mover having one or more bar-shaped magnets longitudinally and vertically embedded therein; and a spring for returning the mover to an initial position thereof, the returning spring being connected to one or both ends of the mover.
