Abstract
A structure for a stator of a reciprocating motor is capable of heightening an efficiency and a reliability of a motor by maximizing the area of a magnetic path at which a flux flows without increasing the whole volume of a reciprocating motor so that the flux, which is to be increased as an overload works on the motor, flows smoothly to thereby restrain generation of a core saturation. The stator structure includes a stator having a hollow cylindrical outer core and an inner core inserted into the outer core and formed as a plurality of mutually coupled hollow cylindrical stacked bodies and a winding coil connected into the outer core and an armature having a permanent magnet attached at one side thereof and movably inserted between the outer core and the inner core.
