BOBBIN STRUCTURE FOR RECIPROCATING MOTOR, PARTICULARLY CONCERNED WITH INCREASING THE STRENGTH OF BOBBIN AND THE NUMBER OF COIL TURNS

摘要

PURPOSE: A bobbin structure for a reciprocating motor is provided to prevent deformation of a bobbin body by using a reinforcement member protruded between internal ends of pole portions of a laminated structure. CONSTITUTION: A bobbin structure for a reciprocating motor includes an external stator(100), an inner stator, and a mover. The external stator includes a bobbin structure(110) sealing a coil wound therein and a laminated structure(120). The laminated structure is made by laminating a plurality of stator cores on the outer circumference of the bobbin structure in a circumferential direction. The inner stator is made by laminating plural stator cores in a cylindrical shape and inserting the result into the external stator while having an interval between cores. The mover is applied between the external and internal stators and moves in a straight line. The bobbin structure includes a reinforcement member(111) protruded between internal terminals of pole portions of the laminated structure to resist against external force.
