Patent ID: 8049374

Claim:
A mover assembly of a motor comprising: a hollow mover body having a circular curved wall with a particular thickness, the outer surface of the circular curved wall being treated to allow subsequent processing, the mover body having a first section to receive magnets and a second section with a plurality of elongated openings formed on and around the outer surface of the circular wall, each opening formed along a lengthwise direction of the mover body, the openings serving to reduce fluid resistance when the mover body reciprocates; a plurality of magnets at equally-spaced locations on the first section of the outer surface of the mover body with corresponding spaces formed between adjacent magnets, each magnet having an upper surface, a lower surface in contact with the first section of the mover body, and side surfaces connecting the upper surface to the lower surface, wherein a portion of each of the side surfaces protrudes from the circular curved wall of the mover body when the magnets are received in the first section of the mover body; and a pliable sheet of fiber-induced resin covering the first section having the plurality of magnets to secure the magnets onto the mover body, wherein the fiber-induced resin of the pliable sheet fills the spaces between adjacent magnets as a result of the pliable sheet being pressed onto the first section of the mover body, and wherein the mover body, the magnets, and the pliable sheet of fiber-induced resin are part of a reciprocating motor.
