Patent ID: 6920682

Claim:
A mover assembly of a reciprocating motor having a mover reciprocally moved at a gap between an inner stator and an outer stator and a plurality of permanent magnets disposed at an outer circumferential surface of the mover, comprising: a hollow cylindrical mover body extended with a certain length between an end of a mounting unit and an end of the mover so as to prevent transformation of a permanent magnet mounting unit for mounting and supporting the permanent magnets and the mover, the hollow cylindrical mover body having a slanting end portion with a decreasing thickness; a plurality of permanent magnets mounted at the mounting unit of the mover and attached at an outer circumferential surface of the mover; and a mixed member made of a fiber and a resin to cover and fix the permanent magnets and to cover the slanting end portion, the mixed member having an end portion with an increasing thickness for covering the slanting end portion of the hollow cylindrical mover body, a total thickness of a combination of the slanting end portion of the hollow cylindrical mover body and the end portion of the mixed member being substantially uniform.
