ABSTRACT:
A mover assembly of a reciprocating motor includes: a mover body disposed at a gap between an inner stator and an outer stator; permanent magnets fixed at an outer circumferential surface of the mover body and reciprocally moved together with the mover body in a direction of an induction magnetic field between the inner stator and the outer stator; and a mixed member made of a fiber and a resin to cover and fix the permanent magnets. The permanent magnets are arranged at an outer circumferential face of the mover body, covered with the mixed member obtained by mixing a fiber and a resin, and hardened to be fixed. Therefore, the permanent magnets can be firmly and easily fixed at the mover body. In addition, by molding the mover body with a non magnetic and non-conductive material, leakage of the magnetic force of the permanent magnets can be prevented.
