MOVER OF RECIPROCATING MOTOR

摘要

PURPOSE: A mover of reciprocating motor is provided to achieve improved efficiency of the motor by minimizing eddy current loss, while increasing reliability by minimizing distortion and damage and reducing air gap. CONSTITUTION: A mover(500) of reciprocating motor, comprises a cylindrical magnet holder(510) inserted between an outer core and an inner core constituting a stator; and a plurality of permanent magnets(520) coupled to a permanent magnet coupling region(F) of the magnet holder. The permanent magnet coupling region has a plurality of through holes(511) each of which has a lengthwise axial length same with the circumferential axial length. Through holes are radially arranged centering from the axis of moving direction of the mover.
