Abstract

A reciprocating power generating module is disclosed, which comprises: a guide having a hollow space along the center axis thereof; an integrated magnet composed of a plurality of magnetic elements which are aligned one next to another in a manner such that poles of each of the magnetic elements are orientated to repel poles of its neighboring magnetic elements; and a coil composed of a plurality of at-least-two-phase windings which are wound around the guide and integrated one winding next to another; wherein the integrated magnet and the coil are arranged in a manner such that the coil is received in the hollow space inside the guide, and the shape of the inner surface of the guide directs the motion path of the integrated magnet.

Claims

1. A reciprocating power generating module comprising:

a guide having a hollow space along the center axis thereof;

an integrated magnet composed of a plurality of magnetic elements which are aligned one next to another in a manner such that poles of each of the magnetic elements are orientated to repel poles of its neighboring magnetic elements; and

a coil composed of a plurality of at-least-two-phase windings which are wound around the guide and integrated one winding next to another;

wherein the integrated magnet and the coil are arranged in a manner such that the coil is received in the hollow space inside the guide, and the shape of the inner surface of the guide directs the motion path of the integrated magnet.

2. A reciprocating power generating module of claim 1, wherein a plurality of microgrooves are formed on the inner surface of the guide.

3. A reciprocating power generating module of claim 1, wherein the guide comprises two end caps respectively at the ends of the guide.

4. A reciprocating power generating module of claim 3, wherein a spring is disposed between the integrated magnet and one of the end caps.

5. A reciprocating power generating module of claim 3, wherein a rope of high strength is strained between both end caps.

6. A reciprocating power generating module of claim 3, wherein a first magnet is bonded to the inner side surface of the end cap.

7. A reciprocating power generating module of claim 6, wherein a second magnet is floating between the integrated magnet and the first magnet.

8. A reciprocating power generating module of claim 1, wherein a fastening structure is formed on each side surface of each magnetic element so as to lock the neighboring magnetic elements firmly.

9. A reciprocating power generating module of claim 1, wherein a ferromagnetic part is interposed between any two neighboring magnetic elements.

10. A reciprocating power generating module of claim 9, wherein the ferromagnetic part is larger than the magnetic elements in radius.

11. A reciprocating power generating module of claim 1, wherein a soft-magnetic part interposed between any two neighboring windings so as to enhance the effect of magnetic flux variation upon the coil.

12. A reciprocating power generating module comprising:

a coil composed of a plurality of at-least-two-phase windings which are assembled one next to another around a soft-magnetic shaft; and

an integrated magnet composed of a plurality of magnetic elements which are aligned one next to another in a manner such that poles of each of the magnetic elements are orientated to repel poles of its neighboring magnetic elements, wherein each magnetic element has a hollow space at the center thereof;

wherein the integrated magnet and the coil are arranged in a manner such that the integrated magnet receives the coil, and the shape of the hollow space inside the integrated magnet directs the motion path of the coil or the integrated magnet.

13. A reciprocating power generating module of claim 12, wherein a fastening structure is formed on each side surface of each magnetic element so as to integrate the neighboring magnetic elements firmly.

14. A reciprocating power generating module of claim 13, wherein a ferromagnetic interposer is disposed between any two neighboring magnetic elements.

15. A reciprocating power generating module of claim 12, wherein a soft-magnetic part is interposed between any two neighboring windings so as to enhance the effect of magnetic flux variation upon the coil.
