STATOR ASSEMBLY FOR RECIPROCATING MOTOR, INCLUDING POLE BLOCKS ARRANGED AT INNER SURFACE OF BOBBIN SO AS TO SUPPORT BOBBIN

摘要

PURPOSE: A stator assembly is provided to prevent deformation of a bobbin by arranging pole blocks at an inner surface of the bobbin such that the pole blocks support the bobbin. CONSTITUTION: A stator assembly comprises a bobbin(111) formed into an empty loop such that a coil is inserted into the loop; a plurality of core blocks(112) formed by stacking a plurality of stator cores, and radially coupled to an outer surface of the bobbin; a plurality of pole blocks(113) inserted into both sides of the bobbin such that each of the pole blocks independently contact both ends of the core block; and a core fixing ring(114) for covering and supporting outer surfaces of the core blocks.
