Abstract
A permanent magnet is rotated about an axis extending between opposing north and south poles. The magnetic field of the rotated permanent magnet interacts with magnetic fields of permanent magnets carried by a shuttle for repelling and attracting the fixed permanent magnets, and providing a linear reciprocating movement of the shuttle responsive to the rotary motion of the rotated permanent magnet.
Claims26
An apparatus comprising:
- a rotatable permanent magnet having a north pole and an opposing south pole aligned within a plane, the rotatable permanent magnet rotatable about an axis within the plane and between the opposing poles;
- a shuttle confined to a linear reciprocating movement generally parallel to the axis;
- first and second fixed permanent magnets affixed to the shuttle, wherein the rotatable permanent magnet is carried therebetween, wherein each of the first and second fixed permanent magnets has a north pole and an opposing south pole therein with the axis extending therebetween, and wherein the permanent magnets are positioned such that rotation of the rotatable permanent magnet is coincident with a repelling and an attracting of the first and second fixed permanent magnets, alternately, and thus the linear reciprocating movement of the shuttle.
An apparatus comprising:
- a motor drive operable for rotating a first shaft about a first axis thereof;
- a plurality of second shafts, each rotatable about a second axis;
- a coupling operable between the first shaft and the plurality of second shafts for rotation thereof each about their respective second axis;
- a plurality of rotatable permanent magnets operable with the plurality of second shafts, wherein each of the plurality of rotatable permanent magnets is defined by a north pole and an opposing south pole within a plane, and wherein each of the plurality of rotatable permanent magnets is rotated by the second shaft about the second axis extending between the north and south poles;
- a shuttle slidably carried for linear movement generally parallel to the first axis;
- and
- a plurality of fixed permanent magnets affixed to the shuttle,
- wherein opposing fixed permanent magnets are positioned on the shuttle for interacting with respective opposing rotatable permanent magnets carried by each of the second shafts,
- wherein each of the fixed permanent magnets is defined by a north pole and an opposing south pole within a plane,
- wherein the rotatable permanent magnets and the fixed permanent magnets are aligned along the second axes;
- and
- wherein rotation of each of the rotatable permanent magnets about their respective second axis results in a repelling and an attracting of the fixed permanent magnets affixed to the shuttle, thus providing a linear reciprocating movement to the shuttle.

An apparatus for converting a rotary motion to a reciprocating linear motion, the apparatus comprising:
- a base;
- a motor affixed to the base, the motor operable for rotating a drive shaft operable therewith about an axis thereof;
- a bracket affixed to the base, the bracket having opposing first and second sides;
- a plurality of auxiliary shafts rotatably carried by the bracket, each of the plurality of auxiliary shafts having ends thereof extending through the first and second sides of the bracket;
- a gear assembly operable between the drive shaft and the plurality of auxiliary shafts for rotation thereof by the drive shaft;
- a plurality of rotatable permanent magnets attached to the plurality of auxiliary shafts, each of the plurality of rotatable permanent magnets carried at each of the ends of the plurality of auxiliary shafts for rotation thereby;
- a shuttle slidably carried by the base for linear movement generally parallel to the axis of the drive shaft;
- a plurality of fixed permanent magnets affixed to the shuttle, wherein one fixed permanent magnet is positioned on the shuttle for interacting with the rotatable permanent magnet carried at the end of the auxiliary shaft, and wherein rotation of the rotatable permanent magnets by the motor results in a repelling and an attracting of the fixed permanents affixed to the shuttle, thus providing a linear reciprocating movement to the shuttle;
- and
- first and second shock absorbers affixed to the base on opposing sides of the bracket, each of the first and second shock absorbers operable for receiving an impact of the shuttle during a reciprocating movement thereof and limiting movement thereof.
